I think I'm correct in saying that shots taken through my SD81S doublet, with my ASI2600MC camera, would benefit from the addition of an IR/UV cut filter. I have a couple of queries, however:-
1. Is there any benefit to using one with my R200SS Newtonian (used with a coma corrector)?
2. If I was shooting with my IDAS NBZ filter, would any IR/UV filter be rendered redundant (but could stay in place) or would it still give benefit?
I ask because where they'd be located, on the internal side of the flattener or coma corrector, I'd prefer to get one for each scope and just leave them attached permanently.
