  • unique and extremely versatile telecompressor system that delivers the finest wide flat fields your SCT is capable of
  • The result is a sharp, wide, flat field, at a fast focal ratio of f/5.9, optical length <50mm
  • Please Note: The close coupling required for the telecompressor to reach focus with binoviewers limits it's use to only the Baader/Zeiss and Celestron binoviewers.

Does the Alan Gee come with the spacer tubes described in the manual or are those purchased separately?

Thank you.

I have an older Meade LX200 7" Maksutov telescope. Can I use the Alan Gee telecompressor with it, both visually and photographically? What additional tubes or accessories would I need?

I have purchased the Alan Gee MkII and need to adapt it to my 2” Moonlite focuser which is mounted to my GSO RC8. It looks like I will need items 16 and 26 to do this. Where is the best place to order these from to be shipped to the states? I have various spacer rings to use with my Altair Astro 183C PROTEC camera that had 17.5 mm flange distance. The AG was purchased from Agena AstroProducts. Thanks, Tim

I see has a special edition Alan Gee Tele for SCT focuser. So can i make one with a regular Alan Gee and a regular 2"-T2 adapter.It seems the SE AG tele has a short threaded tube over AG tele compressor then the 2"-T2 over those tubes...Also if i buy SE AG from Teleskopexpress are the 2 rubber rings and metal ring sold alone if I wanted to use inside my Celestron C5 it would seem there is a middle tube missing from SE AG?Any one else sell SE AG?I just got a Baader 31mm,,very nice glass.Thanks for your time

Can I use the Alan Gee on a C14 (non EdgeHD, it's an old C14 Fastar) for visual use (not CCD)? How much will the focal reduction be (C14 is a f/11 telescope, not f/10)?

Thanks a lot

I would like to use the Alan Gee Telecompressor Mark II with my Celestron 9.25" SCT regular XLT Coatings version (not Edge version). I also have a Baader Planetarium 2 inch Clicklock Mirror Diagonal. Can I use this configuration for visual use? What kind of adapters do I need?

Also, If I want to use the Alan Gee telecompressor for Prime photography using Barlows / Eyepiece Projection, do I need to get additional adapters?

I'm considering getting a Alan Gee Telecompressor for visual & photographic use with a non-Edge Celestron C9.25. What adapters would I need to connect a CCD camera with a 1.25" filter wheel (and possibly an OAG)? For visual use, I have an Astro-Physics Maxbright 2" diagonal.

Thank you.
