It slips into your focuser, just like a Barlow. To minimize focuser in-travel, due to additional length, a mild 15% Barlow effect was designed into Paracorr to effectively push the focus out. Paracorr is recommended for use with all Tele Vue eyepieces because our Plössls, Radians, Panoptics, Naglers, Ethos and Delos eyepieces achieve higher levels of aberration correction than competitive models.

It slips into your focuser, just like a Barlow. To minimize focuser in-travel, due to additional length, a mild 15% Barlow effect was designed into Paracorr to effectively push the focus out. Paracorr is recommended for use with all Tele Vue eyepieces because our Plössls, Radians, Panoptics, Naglers, Ethos and Delos eyepieces achieve higher levels of aberration correction than competitive models. However, Paracorr is also compatible with other eyepiece makes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eParacorr Eats Coma\u003c\/strong\u003e\u003cbr\u003eParacorr can be used with both 2″ and 1¼” eyepieces.

The reducer reduces the focal length by a quarter and corrects the image field. Use it to transform your telescope into a fast astrograph!

We can also offer an adjustment flange for precise adjustment if the reducer \/ flattener is tilted.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe back focus is adjusted depending on the telescope used.

The SCA T-Adapter center loads your camera in the drawtube\/visual back with a simple threading of a compression ring forcing the built-in rubber rings outward radially, thereby centering the camera in the drawtube\/visual back for optimal installation.\u003c\/p\u003e\n\u003ch4\u003eSCA Eliminates Drawtube\/Visual Back Slop\u003c\/h4\u003e\n\u003cp\u003eAll drawtube\/visual back have manufacturing tolerances. And it requires larger diameter to accept various eyepieces and adapters. When the camera adapter is inserted, the gap between the drawtube\/visual back and the inserting device became a slop problem. The rubber rings in the SCA expand radially according to users own adjustment to fill the gaps. This makes your camera seats firmly in your drawtube\/visual back becoming part of your telescope for a secure and repeatable installation.\u003c\/p\u003e\n\u003ch4\u003eSCA Eliminates unstable locking from thumbscrew or unified compression ring\u003c\/h4\u003e\n\u003cp\u003eThe optical axis is shifted when the inserting device is locked in by thumbscrew. In some cases, some poorly made unified compression ring can cause unstable tilt when locking in the drawtube due to loose tolerances between the compression ring, inner groove, and the uneven tip of the locking thumbscrew in a drawtube. The SCA T-Adapter adapts your camera without using the thumbscrew or the unified compression ring.\u003c\/p\u003e\n\u003ch4\u003eSCA Accepts the Imperfection of a Drawtube\/Visual Back\u003c\/h4\u003e\n\u003cp\u003eSmall imperfection inside the drawtube like dents and scratches, the rubber rings fill the gaps and faithfully centers your camera in the tube.

The resulting focal length is 380 mm (F\/3.6) and the corrected image circle is 60 mm in diameter. The off-axis illumination has been improved. The amount of light at the periphery of the field is more than 70%. The amount of light over the 44mm covering the diagonal of a full-format sensor is more than 90%, which is about 50% more than the QE0.73X reducer. Vignetting is almost imperceptible on the cooled CCD and DSLR cameras available on the market today. Finally, the stars are punctual up to the edge of the field.\u003c\/p\u003e\n\u003cp\u003eThe QE0.73X reducer showed a slight violet chromatic aberration at wavelengths around 420 nm; this has been almost completely corrected. The diffraction spot was reduced to about 2\/3 of the spot size at an image circle diameter of about 44 mm. To increase light transmission, the lenses are coated with a broad-spectrum multilayer coating, which reduces reflections to less than half that of a conventional multilayer coating centred on wavelengths close to 500 nm. This reduces ghost images and increases transmission over the entire visible light range.\u003c\/p\u003e\n\u003cp\u003eThe mounting of the reducer unit on the telescope is special. Indeed, unlike other accessories, it is not screwed to the focus. The main body of the reducer is screwed directly to the rear end of the G4 lens, inside the optical tube of the FSQ-106EDX4, in order to reduce the load on the eyepiece holder; the set of adaptor rings on the camera body or camera therefore includes the reducer, which remains fixed.

A f\/10 focal ratio now achieves a f\/6.3, while an f\/11 focal ratio now achieves a f\/7. For visual use, this means you get lower power with the same eyepiece and a wider field of view.

It bend to light to a slightly steeper angle. This refraction effect makes the object appear higher in the sky than if the atmosphere wasn’t there. The degree of refraction depends to a small degree on various things. Like temperature, humidity, observers and height above sea level. It does increases strongly with decreasing altitude of the object. For example, the image of the sun at sunset can actually be elevated by over 0.5°, which is slightly more than one solar diameter.\u003c\/p\u003e\n\u003cp\u003eLike most optical media the refractive (bending) power of the atmosphere is actually dependent on the wavelength of light. This is called optical dispersion. Atmospheric dispersion corrector means that actually the degree of ‘lift’ that the refraction causes depends not only on the angle of the light, but also the colour of that light. Atmospheric dispersion spreads the light from any point source into a vertical spectrum of colours whose length increases the lower the object is in the sky.\u003c\/p\u003e\n\u003cp\u003eThe schematic below illustrates this dispersion effect as light enters the atmosphere and also the lifted elevation of the image. The lift is wavelength dependent and hence the image is separated into different colours.
