If I use this with a Canon EOS 5D Mark IV will it work with my telescope's field flattener which has 55 mm of back focus without any other T-2 system parts?

Is it possible to replace the 42mm thread with the 48mm spacer # 2458405, so I could use this correctly with the MPCC? All your recommandations are about using the protective Canon ring but I have no real need for it since I don't use much filters. There is a question similar to mine but as an answer you refer to a graph of the MPCC which doesn't give me the answer I need... Thanks for your help!

I own a Canon RP and I was wondering if I can use this T-Ring with the Canon adaptor EF-RF on my 127mm Maksutov telescope. Will it work or should I buy the T-Ring for Canon R cameras?

Does the Baader T-Ring for Canon EF (EOS) cameras allow the camera body to rotate relative to the telescope ? By the picture it appears this product is designed for that purpose but just want to confirm.

T-Ringe für Canon EOS eventuell problematisch
Der Celestron-820831/Baader-2408319 Ring soll für Refraktoren problemlos einsetzbar sein. Bei Newton passiert es durch Fertigungstoleranzen des Teleskops, welche 1 - 4 mm ausmachen können, dass der Ring den gewünschten Zweck nicht erfüllt. Es gibt aber eine Short-Version des Rings mit der Baader-Bestellnummer 2408318.
  • Die Short-Version ist für mein Teleskop okay!
  • leider nicht verwendbar für mich
Wie Sie schon richtig angemerkt haben, wurde genaus aus solchen Gründen der Canon EOS Ultrashort Adapter (#2408318) von uns entwickelt.
