Hi everyone, I have a noob question about my optical serup. I have a Celestron C8 with the follwing setup (from the scope bottom to back) : focale reduce 0.63 --> t-adapter SC --> T-ring for Canon DSLR. With all those pieces connected I can achieve the backfocus of 105mm. The problem is that I don't know where to put my 2" L-pro filter...do I have to buy also a filter housing? Thanks to everyone
