I've been doing some astrophotography with my Canon 90D and am looking to step up from just using standard lenses. I'd like to attach my body to an old Meade 2120/LX3. I know I need a t adapter and t-ring.
I see that Meade makes a T adapter (07352), but I'm not sure if it will work on the old scope. They also no longer seem to make t-rings.
Meanwhile, I see that Celestron makes both a T adapter (93633-a) and T-ring for Canon cameras (93419).
So the questions are:
1) will either of these T adapters work with my old Meade 2120/LX3?
2) will the Meade T adapter work with the Celestron T-ring?
Thanks for any help/advice.
