I want to replace an existing straight T2 to 1.25 helical focusser on a TS 60 mm guidescope. I measured the distance from the T2 thread to the focal plain (flange of the eyepiece) as 78 mm when in focus. Will this diagonal/focusser combination work (if I take off the nose piece)?
I have a photo with a ruler if that would help. I just wanted to check I interpreted the optical distances in your diagonals overview correctly.

I wonder if Baader Zenith Prism Diagonal T-2/90 ° with 32mm Prism (T-2 part #14) be the best choice for Meade Infinity 80, 400 mm for terrestrial viewing or there is something other?
And is it good to combine this diagonal with Baader 36mm Hyperion Aspheric 2" Eyepiece and Hyperion Zoom 2.25x Barlow lens, again only for terrestrial viewing?

I have Baader Zenith Prism Diagonal T-2/90 ° with 32mm Prism (T-2 part #14) # 2456005K. I bought a 1.25" Baader ClickLock Eyepiece Clamp. I cannot attach it to this diagonal because the ClickLock and the diagonal are both female threads. How do I attach it?

I am interested in your 1.25 star diagonals. I would like to upgrade from my stock 90 degree on my MAK-CASS. What is the preferred diagonal for this scope mirror or prism. Thanks for your time and consideration. Kind regards.

Overview and Recommended Use: Baader Star Diagonals

Baader Planetarium's star diagonals not only offer the highest mechanical and optical quality, but also have the additional advantage of being part of a large, modular system. They enable very short adaptations as well as 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. Decades of customer feedback led Baader Planetarium to create a seemingly overwhelming amount of adapters. But each adapter has its purpose. This is the reason why you can always find the optical length of each part in the product description, so that you can find the best solution for your needs. To get the most out of them, we recommend that you spend a few minutes reading this brochure. On the following pages you will find a guide on how to choose coating and star diagonal type an overview of the different...
