{"title":"Barlow lenses and focal extenders for telescopes and astrophotography","description":"\u003cp\u003eBarlow lenses and focal extenders for telescopes used in astrophotography are essential accessories for increasing your telescope’s focal length, thereby enhancing the magnification and precision of your observations. By using a Barlow lens or focal extender with your telescope, you can achieve higher magnification levels without changing eyepieces, which is particularly useful for observing planets, the Moon, or deep-sky objects.\u003c\/p\u003e\n\u003cp\u003eAvailable in various magnification factors (1.5x, 2x, 3x, etc.), Barlow lenses and focal extenders are compatible with different types of telescopes and eyepieces. In astrophotography, astrophotography Barlows allow you to capture detailed images while maintaining good optical quality and a proper field of view, offering more flexibility for framing celestial objects and optimizing your shots.\u003c\/p\u003e\n\u003cp\u003eBarlow lenses and focal extenders can be used in conjunction with \u003ca href=\"https:\/\/istronomyplus.com\/collections\/eyepieces\" target=\"_self\"\u003eeyepieces\u003c\/a\u003e, \u003ca href=\"https:\/\/istronomyplus.com\/collections\/diagonals\" target=\"_self\" title=\"\"\u003eprism adapters\u003c\/a\u003e, and \u003ca href=\"https:\/\/istronomyplus.com\/collections\/focusers\" target=\"_self\" title=\"\"\u003efocusers\u003c\/a\u003e, and are among the essential \u003ca href=\"https:\/\/istronomyplus.com\/collections\/optical-accessories\" target=\"_self\" title=\"\"\u003etelescope accessories\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eAt Astronomy Plus, we offer reliable, precise, and easy-to-install Barlows lenses and focal extenders, suitable for both amateur astronomers and experienced astrophotographers.

Barlows amplify the power of a telescope. They can be considered “focal reducers” for eyepieces, or “focal extenders” for objectives. Terence Dickenson, in his Barlow test report in\u003cspan\u003e \u003c\/span\u003e\u003ci\u003eSky and Telescope\u003c\/i\u003e, July 1997, says: “Technology has erased the old objections. A modern Barlow will not degrade your telescope’s optics. Anyone telling you otherwise is using outdated information. Moreover, the highly regarded Nagler eyepieces and their clones have built-in Barlows, ample evidence that the lens is not some detrimental intruder.” Thanks, Terence, for laying the myth of the degrading Barlow to rest.\u003c\/p\u003e\n\u003cp\u003eA high quality Barlow must be properly designed and manufactured in order to avoid compromising a telescope’s color and spherical aberration corrections. The “invisibility” of Tele Vue’s 2-element Barlows has been noted in test reports in the astronomy magazines. However, by the nature of its negative power lens, a Barlow will do more than just increase magnification, regardless of the number of elements.\u003c\/p\u003e\n\u003cp\u003eThe diverging rays leaving the Barlow result in moving the exit pupil further out, thereby extending the eye relief. In short to medium focal length eyepieces the change is not noticeable. However, in the case of long focal length eyepieces, the increase can be significant and not without performance consequences.\u003c\/p\u003e\n\u003cp\u003eVignetting can occur due to the altered ray path, when the eyepiece’s lenses are not large enough in diameter to allow all the rays to make it through. Shorter Barlows, or ones with too much magnification, only exacerbate the problem because the ray path entering the eyepiece is steeper.\u003c\/p\u003e\n\u003cp\u003eWe had to go beyond the Barlow concept to achieve the goal of a compact, high power, fully corrected image amplifier. The Powermate™ consists of a negative doublet plus a positive “pupil-correcting” doublet. This 4-element system provides the magnifying function of a Barlow without its limitations by restoring the field rays back to their original direction, as if the Powermate™ were not there.

Barlows amplify the power of a telescope. They can be considered “focal reducers” for eyepieces, or “focal extenders” for objectives. Terence Dickenson, in his Barlow test report in\u003cspan\u003e \u003c\/span\u003e\u003ci\u003eSky and Telescope\u003c\/i\u003e, July 1997, says: “Technology has erased the old objections. A modern Barlow will not degrade your telescope’s optics. Anyone telling you otherwise is using outdated information. Moreover, the highly regarded Nagler eyepieces and their clones have built-in Barlows, ample evidence that the lens is not some detrimental intruder.” Thanks, Terence, for laying the myth of the degrading Barlow to rest.\u003c\/p\u003e\n\u003cp\u003eA high quality Barlow must be properly designed and manufactured in order to avoid compromising a telescope’s color and spherical aberration corrections. The “invisibility” of Tele Vue’s 2-element Barlows has been noted in test reports in the astronomy magazines. However, by the nature of its negative power lens, a Barlow will do more than just increase magnification, regardless of the number of elements.\u003c\/p\u003e\n\u003cp\u003eThe diverging rays leaving the Barlow result in moving the exit pupil further out, thereby extending the eye relief. In short to medium focal length eyepieces the change is not noticeable. However, in the case of long focal length eyepieces, the increase can be significant and not without performance consequences.\u003c\/p\u003e\n\u003cp\u003eVignetting can occur due to the altered ray path, when the eyepiece’s lenses are not large enough in diameter to allow all the rays to make it through. Shorter Barlows, or ones with too much magnification, only exacerbate the problem because the ray path entering the eyepiece is steeper.\u003c\/p\u003e\n\u003cp\u003eWe had to go beyond the Barlow concept to achieve the goal of a compact, high power, fully corrected image amplifier. The Powermate™ consists of a negative doublet plus a positive “pupil-correcting” doublet. This 4-element system provides the magnifying function of a Barlow without its limitations by restoring the field rays back to their original direction, as if the Powermate™ were not there. The result is a pure magnification increase.\u003c\/p\u003e\n\u003ch4 class=\"pageSectionTitle\"\u003eUnique Benefits and Applications for Powermates™\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eVignetting, edge field aberrations and pupil movement – all introduced when using Barlows with long focal length eyepieces, are minimized.\u003c\/li\u003e\n\u003cli\u003eTelecentric operation (field rays leave parallel to optical axis, unlike Barlow lenses which diverge rays).

Once the thumbscrew has been secured in place, the brass ring keeps your eyepiece in the Barlow instead of relying on the tip of the thumbscrew itself, offering a better grip and protecting the barrel from scratches.\u003cbr\u003e\u003cbr\u003eThe barrel of the Celestron X-Cel LX 2x Barlow is threaded to accept 1.25” filters, allowing you to change eyepieces without removing and re-attaching the filter from each eyepiece barrel.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv class=\"tab-content js-accordion-content rte\"\u003e\n\u003cp\u003e\u003cstrong\u003eAdditional Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQuality X-Cel LX 2x Barlow doubles the magnification of any 1.25” eyepiece\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003e3-element apochromatic, fully multi-coated optics offer up bright, sharp images\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eA rubber grip helps to avoid accidental drops\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eBarrel is threaded to accept standard 1.25” filters\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/li\u003e\n\u003cli\u003eA brass compression ring holds the eyepiece firmly in place\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"box-sizing: inherit; border-collapse: collapse; border-spacing: 0px; text-align: left; width: 1200px; color: #333e48; font-family: 'Open Sans', Arial, Helvetica, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\" id=\"product-specs-list\" class=\"table-open\"\u003e\n\u003ctbody style=\"box-sizing: inherit;\" id=\"spec-block-1\"\u003e\n\u003ctr style=\"box-sizing: inherit; border-bottom: 1px solid #e4e8ea;\"\u003e\n\u003ctd style=\"box-sizing: inherit; padding: 13px; font-size: 14px; height: 43px; width: 300px; font-weight: bold;\"\u003eMagnification:\u003c\/td\u003e\n\u003ctd style=\"box-sizing: inherit; padding: 13px; font-size: 14px; height: 43px;\"\u003e2x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"box-sizing: inherit; border-bottom: 0px;\"\u003e\n\u003ctd style=\"box-sizing: inherit; padding: 13px; font-size: 14px; height: 43px; width: 300px; font-weight: bold;\"\u003eOptical Coatings:\u003c\/td\u003e\n\u003ctd style=\"box-sizing: inherit; padding: 13px; font-size: 14px; height: 43px;\"\u003eFully Multi-Coated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eIn the Box\u003c\/h3\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eCelestron X-CEL LX 1.25\" 2x Barlow Lens\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eCelestron 2-Year Warranty\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":43125764620517,"sku":"CEL-93529","price":174.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/celestron-x-cel-lx-1-25-2x-barlow-lens-93529-astronomy-plus-1.webp?v=1690484937"},{"product_id":"celestron-omni-1-25-2x-barlow-lens-93326","title":"Celestron Omni 1.25\" 2x Barlow Lens (93326)","description":"\u003ch2\u003eCelestron Omni 1.25\" 2x Barlow Lens\u003c\/h2\u003e\n\u003cp\u003eA Barlow lens is the astronomy accessory that keeps on giving! Insert it between your eyepiece and your telescope to get double the magnification instantly. Let’s say you have two eyepieces in your accessory case, a 10mm and a 25mm. Add a Celestron Omni 2X Barlow Lens to the mix, and now you have four magnifications to choose from. Combining this lens with the 25mm provides double the magnification, or the equivalent of a 12.5mm eyepiece, while the 10mm gives you the power of a 5mm eyepiece. \u003cbr\u003e\u003cbr\u003eEye relief is the distance your eye has to be from the first lens in the eyepiece in order to see the full field of view. When you use a Barlow lens with an eyepiece, you get double the magnification, but the eye relief is not affected. This is a good thing, because normally the shorter the focal length of the eyepiece, the less eye relief you have. In other words, a standard 10mm eyepiece, as a general rule, will have better eye relief than a 5mm eyepiece. Bonus! \u003cbr\u003e\u003cbr\u003eThe Celestron Omni 2x Barlow comes in a sleek, silver package. The two-element optics are fully multi-coated, and the edges of the lenses are blackened to cut down on internal reflections. The 1.25” barrel will fit in standard 1.25” focusers and diagonals, and the Barlow will accept 1.25” eyepieces.

When used with the included T-2 adapter and a DSLR (with T-ring, such as the new Baader Protective DSLR T-rings), the projection ratio is approx 2.2X.\u003c\/div\u003e\n\u003cdiv style=\"box-sizing: inherit;

This means that the off axis beam arrives at the image plane with the same angular geometry as the axial rays. All field elements look as if they where on axis, across the image plane and - unlike to a barlow lens - the edge field rays are not tipped bundles.\u003c\/p\u003e\n\u003cp\u003eBecause all the principal rays across the image plane are perpendicular to the image plane, the rays at the edge of the field will pass through an etalon just in front of the focal plane with exactly the same geometry as the rays on axis. So in an f\/30 telecentric optical arrangement, the etalon sees the exact same geometry clear across the field, and the spectral bandpass does not shift in wavelength across the entire field of view.\u003c\/p\u003e\n\u003cp\u003eStarting from an aperture ratio of ~f\/15 (+2x Telecentric), ~f\/10 (+3x Telecentric) or ~f\/7.5 (+4x Telecentric), the Baader TZ-systems will create a parallel beam with ~f\/30 aperture ratio. In the case of largely deviating telescope focal lengths, the clear objective aperture of the telescope should be reduced in diameter to the point that the final resulting f\/ratio is close to f\/30 again (we offer a suitable iris-diaphragm for this purpose, or the user can construct their own aperture stop).\u003c\/p\u003e\n\u003cp\u003eTZ-system working distances – when measured from their rear lens – range from 200mm for the TZ-2 to 230 mm for the TZ-4 - to 250 mm for the TZ-3. This provides enough room for the H-alpha filter housing and most any accessories, e.g. a Baader 2\" star diagonal, Binoviewer, or any conceivable camera device. The generous room of the TZ-3 will also accommodate a binocular viewer when it is mounted onto the SolarSpectrum body by means of a Baader BBHS T-2 star diagonal. All TZ-coatings are matched to the different lens glass-substrates and optimized for maximum throughput at 656 nm. Still the TZ-3 especially also works for CaK at 396 nm. The TZ-3 Strehl-ratio is well above 80% at 396 nm\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"data-table\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"first odd\"\u003e\n\u003cth class=\"label\"\u003eMANUFACTURER\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eBaader Planetarium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eSKU (#)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e2459257\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eEAN CODE\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e4047825008695\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eWEIGHT (KG)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e0.37\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eFOCAL LENGTH EXTENSION\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e3x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eUSAGE\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003efor H-alpha observation with SolarSpectrum filters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eINNER CONNECTION (LENS SIDED)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eThread, T-2 (M42 x 0,75), 2\" (50,8mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eOUTER CONNECTION (LENS SIDED)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eThread, 2\" (50,8mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"last odd\"\u003e\n\u003cth class=\"label\"\u003eOUTER CONNECTION (EYEPIECE\/-CAMERA-SIDED)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eThread, T-2 (M42 x 0,75), 2\" (50,8mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003eBaader Research Grade TZ-3 Telecentric System (3x focal length)\u003c\/p\u003e\n\u003ch3\u003eWarranty\u003c\/h3\u003e\n\u003cp\u003e\u003ca rel=\"noopener\" href=\"https:\/\/istronomyplus.com\/pages\/baader-warranty\" target=\"_blank\"\u003eBaader 2-Year Warranty\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0267\/1172\/0013\/files\/baader_telecentric_systems_tzs_for_h_solar_filters.pdf?v=1590568855\" target=\"_blank\"\u003eBaader Telecentric Systems (TZS) for H-α solar filters\u003c\/a\u003e\u003c\/p\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":46510561886437,"sku":"BAA-TZ-3 (Baader #2459257)","price":648.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/6_18efffa8-81d3-40f4-980f-2dc92bce25bb.webp?v=1739042195"},{"product_id":"baader-sundancer-ii-telecentric-system-tz-3s","title":"Baader SunDancer II Telecentric System","description":"\u003ch1\u003eBaader SunDancer II Telecentric System\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eAchromatic 3x telecentric system\u003c\/li\u003e\n\u003cli\u003eFour-lens optical design, BBAR (Broad-Band Anti-Reflection) coating\u003c\/li\u003e\n\u003cli\u003eAnti-reflective thread and blackened lens edges against reflections and for maximum contrast\u003c\/li\u003e\n\u003cli\u003eImage circle 35mm in 65 mm distance to T-2 threaded base\u003c\/li\u003e\n\u003cli\u003e1¼\" and 2\" nosepiece with 1¼\" filter thread, T-2 thread on camera side\u003c\/li\u003e\n\u003cli\u003eThe optical design places the telescope's focal point 28 mm behind the end of the 1¼\" nosepiece\u003c\/li\u003e\n\u003cli\u003e5-year warranty if handled properly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease note: when using as a telecentric for H-alpha or CaK solar observation, it is mandatory to include a suitable D-ERF filter in front of the telescope aperture to prevent damage to the lens groups in the telecentric due to overheating.

Due to the parallel beam of light, it is very good-natured with regard to the working distance: While the magnification factor of a Barlow lens changes with the distance to eyepiece or camera (zoom eyepieces are also based on this principle), the magnification factor and image quality of the TZ-3 do not change, even if the new focal point deviates very significantly from the working distance of the optical design (65 mm).\u003cbr\u003e\u003cbr\u003eThe achromatic SunDancer II TZ-3S illuminates an image circle of 35mm at a distance of 65mm from the base body, ideal for the small sensors of modern, fast planetary cameras that require high magnifications for photographing the moon and planets. The contrast is better than with simple barlows or the eyepiece projection often used for high magnifications. With the 3x telecentric system, the high magnifications which are necessary for visual observations can also be achieved with long focal length orthoscopic eyepieces. The interpupillary distance of the eyepieces used does not change either.\u003cbr\u003e\u003cbr\u003eThe connection on the telescope side is made via a dual 1.25\"\/2\" nosepiece with safety kerfs (these prevent tilting due to an incorrectly positioned safety groove and at the same time provide a secure hold). On the camera side, the T-2 thread provides a tilt-proof, fixed connection even to heavy cameras or to T-2 eyepiece clamps. For the T-2 thread, adapter rings are available for almost all common connection systems (e.g. M48 \/ 2\"\/ M68).\u003c\/p\u003e\n\u003ch2\u003eComparing telecentric systems with Barlow lenses\u003c\/h2\u003e\n\u003cp\u003eA telecentric system extends the focal length similar to a Barlow lens, but with parallel rays of light. This means that the working distance is almost the same, and the quality and image scale remain the same. At the same time, the TZ-3S delivers a high-contrast image. For the following comparison shot, a church steeple was photographed with an APS-C DSLR with the same camera settings; once with a Baader Q-Barlow, which was brought to a triple magnification factor with spacer sleeves, and once with the TZ-3S. On cameras with less than 35mm image circle, edge shading is no longer a problem and you benefit from higher contrast of the telecentric.\u003c\/p\u003e\n\u003ch2\u003eComparison of Baader SunDancer II H-alpha-Filter and Baader SunDancer II TZ-3S\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eThe telecentric system of the Baader SunDancer II H-alpha Filter (#1363056, € 3345,-) is the same as the Baader SunDancer II 3x telecentrics TZ-3S, but additionally contains a 2nm (FWHM) blocking filter. It shimmers golden when you look into the SunDancer from the telescope side. This blocking filter is absolutely necessary to protect the actual H-alpha filter from solar radiation. The 3x telecentric system is available as Baader SunDancer II 3x Telecentric TZ-3S without block filter, e.g. for use with other H-alpha filters. The blocking filter, however, is not available separately.\u003cbr\u003e\u003cbr\u003eThe blocking filter reflects the sunlight just before the etalon and the telecentric system. This protects the etalon from excessive heat. In addition, an etalon also transmits wavelengths that are a multiple of the desired transmission line; these are also blocked by the blocking filter, too.\u003c\/p\u003e\n\u003cp\u003eTZ-optical systems are essential for undeteriorated performance of heated SolarSpectrum filters:\u003c\/p\u003e\n\u003cp\u003ePlease note that for H-alpha observations below 1 Ang halfbandwidth (FWHM) a telecentric lens system is absolutely mandatory, in order to achieve the recommended focal ratio of f\/30 to (preferably) f\/40! Because only with a telecentric approach you can create a perfectly parallel optical path which is essential for the unrestricted function of such a complicated etalon.\u003cbr\u003e\u003cbr\u003eA TZ-lens-system is an ESSENTIAL prerequisite. One could also optically - or by means of a Barlow lens - bring a telescope to a focal ratio of f\/30, but this does not mean at all that a parallel optical path is created. And mind you, a still slightly conical optical path with f\/30 sent into an etalon with 0.5 Ang FWHM would only provide the contrast as if the filter had a FWHM of 0.7 Ang or much worse.\u003cbr\u003e\u003cbr\u003eIt doesn't have to be a TZ-4. The 2\" Research Grade TZ-3 Telecentric System (3x focal length) (#2459257) with 46mm clear aperture is much better in terms of optical calculation than the 20 year older TZ-4. So it makes sense for the user to start with a TZ-3 RG and rather stop down the telescope aperture to get to f\/30. This will bring out the real contrast of the chosen SolarSpectrum-filter much better than with a poorly matched system where, for example, the older TZ-4 has a smaller clear aperture than the Solar Spectrum-Etalon would require. In the long run, a newly calculated, large RG TZ-4 is in preparation - it is worth to wait for it and to get familiar with H-alpha observation with the TZ-3 first. In the end one will certainly need both systems (RG-TZ-3 and RG-TZ-4) and adjust the telescope aperture individually - as the system would require to enable an f\/ratio of f\/30 at minimum or f\/40 as optimum.\u003cbr\u003e\u003cbr\u003eOnly AFTER the H-alpha etalon you can extend the field size by reducing the f-ratio with adding the new ResearchGrade telecompressor 0.4 into the optical train.\u003cbr\u003e\u003cbr\u003eBasically - a Barlow lens has no place in an H-alpha system!\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable id=\"product-attribute-specs-table\" class=\"data-table\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"first odd\"\u003e\n\u003cth class=\"label\"\u003eMANUFACTURER\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eBaader Planetarium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eSKU (#)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e1363070\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eEAN CODE\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e4047825042903\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eFOCAL LENGTH EXTENSION\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003e3x\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"odd\"\u003e\n\u003cth class=\"label\"\u003eUSAGE\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003efor H-alpha observation with SolarSpectrum filters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"even\"\u003e\n\u003cth class=\"label\"\u003eOUTER CONNECTION (LENS SIDED)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eBarrel, 1¼\", 2\" (50,8mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"last odd\"\u003e\n\u003cth class=\"label\"\u003eOUTER CONNECTION (EYEPIECE\/-CAMERA-SIDED)\u003c\/th\u003e\n\u003ctd class=\"data last\"\u003eThread, T-2 (M42 x 0,75), 1,4\"(35mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003eBaader SunDancer II Telecentric System\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eWarranty \u0026amp; Manuals\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/istronomyplus.com\/pages\/baader-warranty\" rel=\"noopener\" target=\"_blank\"\u003eBaader 2-Year Warranty\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0267\/1172\/0013\/files\/baader_sundancer_ii_h_alpha_filter_manual_and_applications_tipps.pdf?v=1631973767\" target=\"_blank\"\u003eBaader SunDancer II H-alpha Filter – Manual and Applications Tipps\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0267\/1172\/0013\/files\/baader_sundancer_ii_quickstart.pdf?v=1631973766\" target=\"_blank\"\u003eBaader SunDancer II - Quickstart\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0267\/1172\/0013\/files\/solarspectrum_h_alpha_filter_baader_planetarium_telecentric_systems_346e0461-a02c-49c7-bbef-768fd3c3e48c.pdf?v=1700410227\" target=\"_blank\"\u003eSolar Spectrum H-alpha-filter and Telecentric Systems - Application and Tips \u003c\/a\u003e\u003c\/p\u003e","brand":"Baader Planetarium","offers":[{"title":"TZ-3S","offer_id":49098869440741,"sku":"BAA-TZ-3S (Baader #1363070)-1","price":532.0,"currency_code":"CAD","in_stock":true},{"title":"TZ-4S","offer_id":49098869473509,"sku":"BAA-TZ-4S (Baader #1363080)","price":561.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/5_31d5080c-d52b-4ae9-b420-4d6ed76e2ff5.webp?v=1739046285"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/collections\/barlows-and-focal-extenders-astronomy-plus_579cbb85-b543-4cac-a1d2-2d48f13b867d.jpg?v=1715807862","url":"https:\/\/istronomyplus.com\/collections\/barlows-focal-extenders.oembed","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
