Of course, also the BBHS®-mirrors make very short adaptations possible and provide threads for direct connections to a telescope or a Baader focuser, as well as adaptation to a wide range of threads for torsion-free use with heavy or long accessories, such as binoviewers. Even a 2\" filter can be inserted permanently into the eyepiece-side of the 2\" nose-piece, e.g. as dust protection, so that you can still use the 2\" filter thread on the telescope side as usual.\u003c\/p\u003e\n\u003cp\u003eSilver is the first choice for mirror materials, but it must be protected against corrosion – otherwise simple silver mirrors will tarnish over the years. Popular dielectric mirrors are more robust, but usually reflect only visible light between about 400 and 700 nm. For a viewing experience comparable to looking through the telescope without a mirror, Baader’s BBHS® mirrors use an additional\u0026amp;nbsp;BBHS® First Surface Silver layer, elaborately sealed against corrosion. This is responsible for the outstanding brilliance and richer colours compared to simpler prisms. BBHS® is an abbreviation for Broad Band Hard Silver; the silver layer is stabilized long-term by a hard protective coating. Its weather resistance is comparable to an AlSiO₂ coating on a Newtonian telescope mirror.\u003c\/p\u003e\n\u003cdiv class=\"columnGroup-root-fOH pagebuilder-column-group\"\u003e\n\u003cdiv style=\"display: flex;\" class=\"columnGroup-root-fOH pagebuilder-column-line\"\u003e\n\u003cdiv style=\"align-self: stretch; display: flex; flex-direction: column; justify-content: flex-start; width: 58.3333%;\" class=\"column-root-7Tj pagebuilder-column\"\u003e\n\u003cdiv class=\"text-root-0Rs\" role=\"presentation\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"align-self: stretch; display: flex; flex-direction: column; justify-content: flex-start; width: 41.6667%;\" class=\"column-root-7Tj pagebuilder-column\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"text-root-0Rs\" role=\"presentation\"\u003e\n\u003cp\u003eCompared to purely dielectric coatings, BBHS\u003csup\u003e®\u003c\/sup\u003e provides a much broader spectral range with \u003cstrong\u003e98–99% reflection from just above 390 nm to 2000 nm,\u003c\/strong\u003e and it maintains high reflectivity even with varying viewing angles – the silver layer produces no stray light whatsoever. A trained eye will especially see a greater colour range when using short focal length APO refractors. Particularly in planetary observation at the highest magnifications, a noticeable increase in colour intensity can be easily observed compared to all previous coatings. Additionally, a clear increase in contrast is noticeable due to the absence of any stray light. Only \u003cstrong\u003eglass-ceramic\u003c\/strong\u003e is used as the substrate for the BBHS\u003csup\u003e®\u003c\/sup\u003e coating, ensuring extremely fast temperature adaptation and image stability in combination with the \u003cstrong\u003eCNC-milled aluminium housings\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIt has been proven that \u003cstrong\u003esilver, in combination with temperature-resistant glass-ceramic\u003c\/strong\u003e, offers the absolute best viewing experience with a complete absence of stray light. Try it – the difference is impressive. Afterwards, you will want to observe planets only straight-through or with these hard-silver–coated Sitall mirrors. As a guideline, prisms are recommended for telescopes with a focal ratio of about f\/6 to f\/7 or slower, and for faster optics, the\u003cstrong\u003e BBHS\u003csup\u003e® \u003c\/sup\u003emirros are preferable\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIn addition to the sealed BBHS\u003csup\u003e®\u003c\/sup\u003erear-surface coating, the prisms feature the proven Phantom Coating\u003csup\u003e®\u003c\/sup\u003e Group anti-reflection treatment.\u003c\/p\u003e\n\u003cp\u003eThe precisely fitting  \u003cstrong\u003e2\" ClickLock\u003csup\u003e®\u003c\/sup\u003e eyepiece clamp \u003c\/strong\u003esecurely holds even heavy accessories with a simple 20° twist. By cleverly using leverage, the clamping force is multiplied many times. The inserted accessory is held on three sides, similar to a quick-release chuck, preventing any tilting movement. Every eyepiece or measuring device is automatically aligned parallel to the optical axis – even in the case of diameter tolerances.\u003c\/p\u003e\n\u003cp\u003eThe BBHS\u003csup\u003e®\u003c\/sup\u003e mirror is mounted in a \u003cstrong\u003eCNC-machined aluminium housing \u003c\/strong\u003eand rests stress-free on an adjustable cradle. Just like a high-quality refractor objective, the mirror can also be collimated. This allows the realisation of fully adjustable systems, for example for the construction of binocular telescopes. As with a premium refractor, you will not need to change the collimation during normal use: the 3-point alignment is set at our factory so that the image shows no noticeable rotation around its centre when the star diagonal is rotated by 180° in a correctly aligned eyepiece clamp. Optical and mechanical axes are perfectly matched on our optical test benches. Therefore, make sure to rule out all other potential sources of error – such as a tilted focuser – before adjusting the collimation.\u003c\/p\u003e\n\u003cp\u003eWhen a BBHS\u003csup\u003e®\u003c\/sup\u003e mirror leaves our factory, the optical and mechanical axes are aligned rotationally symmetrically with each other on the optical bench. Please note that once the collimation is changed, the warranty on the factory collimation of the BBHS\u003csup\u003e®\u003c\/sup\u003e star diagonal becomes void. All other warranty coverage remains unaffected. Should you notice immediately after purchase that the optical axis is not correct, please contact the dealer from whom you bought the device without
