Newby Question. I have an Esprit 100ED, Question that where would you place a 2" filter in the image train? Would it go in front of the flattener going into the focuser or on the back end of the flattener? I have an ASI 294MC coming soon. I have a 2" L-Pro filter that i've been using on my WO Redcat 51 & Nikon D850, but want to use is with my 100ED when the new camera arrives.
Any and all advice is alway welcome.
Thanks.
