For context, I use DSLR with a Canon T-Ring that fits into 1.25” telescope lenses. Recently I purchased a Canon 5D Mark iii because of its Intervalometer attachment ports.
The mirror is much larger than my previous camera. When I look inside the 1.25” hole through the mounted T-ring, the corners of the mirror are blocked by the T adapter.
I do not own any 2” eye piece telescopes. Do I need to switch entirely? Or will it not affect photos too much to keep using a 1.25” T adapter for my photos.
(I have not tested this yet because I still need to buy a new star tracker mount that can support the weight of the new camera)
This is the last M42 photo of the year as Orion starts to dip down below the horizon at night! This was my first nebula ever captured like most people and over 2 years of capturing it, this is easily my best one.
