I purchased the Hyperion Zoom and the MPCC Mark III. Can you tell me how to adapt the eyepiece to the coma corrector?
I also want to use other eyepieces. How do I know the right distance between fieldstop position and the MPCC?

Baader Universal Filter Changer (UFC): The UFC camera-side adaptors (Part 4)
The UFC Camera Adaptors: In this latest blog on the Baader UFC System, we will look at the UFC camera-side adaptors. At present there are nine (9) different adaptors that will allow cameras to be attached to the (camera-side) of the UFC Base unit. These are shown in the image below. The image shows the type of fitment to the camera (e.g. T-2, FLI etc), the product code and also the optical path length (thickness) of the adaptor (which is important when using the UFC system with e.g. focal reducer where the camera sensor needs to be positioned at a particular distance from the reducer - we will cover this in a later post). All of the nine adaptors have the following common features: made of aluminium anodised matt-black have countersunk holes are attached to the UFC-base unit using 8 hex screws supplied with the adaptor for secure fitment (screws are flush fitting when fully tightened) The image below shows the camera side of the UFC Base on which all the UFC camera-side adaptors are fitted. Below is an image of a UFC camera adaptor showing the 8 countersunk holes in which the hex screws are inserted for...

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...

Perfect coma correction with Baader-MPCC – but how to adapt eyepieces?
We received the following question and found it important to write an extensive answer for other customers. QUESTION: I purchased the Hyperion Zoom and the MPCC Mark III. Can you tell me how to adapt the eyepiece to the coma corrector? I also want to use other eyepieces. How do I know the right distance between fieldstop position and the MPCC? ANSWER: It is easy to produce an adjustable 1¼" eyepiece adapter for the Baader-MPCC coma corrector, offering a variable optical length from 49 to 64 mm, by using the following two parts: Baader focusing eyepiece clamp 1¼"/T-2 (item no. 2458125 / # 8a) Baader VariLock 20-29 mm T-2/T-2 adapter (item no. 2956929 / # 25Y) Combining these parts on top of the MPCC T-2-thread and rotating both adapters into the shortest optical length will provide an optical distance of 49 mm for an fully inserted eyepiece with 1¼" barrel. The MPCC is designer for a distance of 55mm to camera sensor or fieldstop. That means, the fieldstop inside an eyepiece could be placed up to 6 mm above the (upper) end of the 1¼" eyepiece barrel, in order to adjust for the 55 mm optical distance of the MPCC, which...
