Product QuestionsQuestion by: Alexander Arnott on Dec 31, 2016 11:19:00 AMThe only way to add a 2" filter inline (and only with a Canon DSLR) would be with the Baader Protective T ring for Canon: https://www.optcorp.com/baader-protective-wide-t-ring-for-eos-w-2-nosepiece.html. The included 2" nosepiece can be removed, a 2" filter can be threaded inside, and an included stepdown adapter to T-thread can then allow attachment to this T-adapter.
There are currently no options to use 2" filters with other DSLR brands and this adapter at the moment, unfortunately.Answer by: Chris Hendren (Admin) on Jan 2, 2017 11:10:00 AMIs this 2" adapter of 1.25"? if it's the latter then what would you recommend as i need 2" adapter to be used for astro cameras like QHY 183c or a full frame DSLR cameraDo I need this T-adapter if I buy the .7 focal reducer?

For the 9.25" Edge, you would be better off with the CE-93646 which fits the larger 3.29" thread. For a 9.25" standard SCT, the CE-93633-A is a better match - especially if you use an f/6.3 reducer.Answer by: Chris Hendren (Admin) on Apr 15, 2015 11:06:00 AM
