Optical tube lengths of 2" Clicklock and BBHS mirror diagonals
Recently we received the following questions on our 2" Clicklock Diagonal Mirror and wanted to answer including the below illustrations for other customers: Please note: all of the below information is also valid for our 2" BBHS mirror and prism diagonals (with slight differences in the specifiations such as optical tube lengths – please compare with specs on the product pages). According to image below is the optical path mentioned in technical data (112mm for #2956100 and 109mm for #2956100Z) measured along optical axis from point A to B or point A to C? what is the dimension from point B to C? Can 2” barrel (at point A) be removed from #2956100 and exchanged with another accessory (is it available?) to change the diagonal to #2956100Z (M68x1 thread)? Please note below our answer and adjusted graphic: The optical path of 112mm is measured A to C. The lightway from A to B would be ~71,5mm. Please note that the final endpoint of B is 3,5mm outside of the prism body (as illustrated in the below graphic), it looks just like point A in your drawing The Dimension from B to C (height of the SC-ClickLock) is 44mm. It is overlapping the...

The Baader Astro T-2 System™
For over 30 years we have focused on the Astro T-2 thread system (M 42 x 0.75 mm); virtually every telescope manufacturer must offer this thread far ahead of the focal point of his instrument, such a universal T-ring (for DSLR cameras) can be connected. The only exceptions are (still) Russian equipment, there the thread diameter is the same, but the pitch is still 1mm per revolution - rather than 0.75mm! Therefore, we offer among other things a "Russians adapter". At only 7mm additional optical length it can allow so many Russian lenses or telescopes to be compatible with an international Astro T-2 (M 42 x 0.75mm) connector! For the sake of better recognition mostly are marked. See marking small 'a' or small 'i' in the respective indication! "a"; identifies an external thread (male); or, if Ø sign which a diameter, "i"; - a female is always (female) or - Ø character - an inner diameter. The Optical Length The optical length describes the extension of the optical path caused by an adapter or accessory when inserted into the beam path of the telescope. The values listed in the system table rounded to 1/2 mm. For pure threaded adapters...
