If this is attached to the T-2 1C prism diagonal, will the nosepiece of a 1.25" eyepiece touch the prism surface? I'm concerned because the measured nosepiece length is 26mm, while the stated length of this clamp is only 20mm.

Ultrashort-1¼ review
I used it with 32 mm Soviet TAL 1 telescope oculars. I redesigned the ultrashort-1¼ to 32 mm. I want to use it with Soviet lens MC MTO-11CA 10/1000. I would like to get some advice about this clamp, if I can use it with this product : Baader 21mm Hyperion 68° Modular Eyepiece. Probably I will need extension tube 0,75 mm - 42 mm, is there a possibility to buy extension tubes separately or do I have to buy them all together. I saw it on your website.
  • Very satisfied with the product, now i can use details from Soviet times, made it compatible.
  • Nothing to complain about

Thanks for your review. Yes, you can buy the extension tubes seperately. We offer the following lengths:
Baader T-2 / 7.5 mm Extension Tube #1508155
Baader T-2 / 15 mm Extension Tube #1508154
Baader T-2 / 40 mm Extension Tube #1508153
as well as a T-2 Fine-Adjustment ring 1mm (gold) - Aluminium #2457913
and the variable adapters
Baader VariLock 29, lockable T-2 ExtensionTube 20-29mm with spanner tool # 2956929
Baader VariLock 46, lockable T-2 ExtensionTube 29-46mm with spanner tool # 2956946

Also, the Ultrashort-Clamp works fine with the Hyperion eyepieces. It is still long enough, and the locking screws are slim enough, so that the wider eyepieces have got no problem.
