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).
Customer question: According to image below
- is the optical path mentioned in technical data (112mm for 2" ClickLock® Mirror Diagonal (#2956100 , € 296,- ) and 109mm for M68 ClickLock® Mirror Diagonal (#2956100Z , € 309,- ) 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)?
- 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 3,5mm outer part of B
- Yes, the 2" Barrel can be removed without problems, revealing a 2" inner thread. This thread however is also an adapter M55/2" (not available as single item) and can only be removed from the Clicklock mirror body with the help of our
Adjustable pin type face wrench ø 2mm

.
After this adapter has been removed, you can change the diagonal to our M68 ClickLock® Mirror Diagonal (#2956100Z , € 309,- ) Zeiss Clicklock with the help of the Adapter M55a to M68a – for 2" diagonals (#2956110 , € 52,- ) . This adapter is already included in the M68 Clicklock diagonal mirror version (2956100Z). The M68 version offers the largest telescope sided opening aperture on the market - with 51mm
Please also note that by removing the Clicklock clamp on the eyepiece side (revealing the M55/2" Ring just like on side A), you can attach our Adapter 2"/SCTa to T-2a – with 2" filter thread (#1508035 , € 41,- ) which allows for example mounting of our 1¼" Eyepiece Clamp to T-2i – with rotational focusing (#2458125 , € 46,- ) .
Alternatively you can add our Inverter ring 2"/SCTa (female to male) – with 2" filter thread (#1508020 , € 31,- ) to directly attach for example our Hyperion Zoom eyepiece as shown on the left on the example of our former Hyperion Zoom MK III. The picture to the right shows the same usage with our current Hyperion Universal Zoom MK IV eyepiece.
