Toucam SP900NC which filter to get?
Hi All.
Well I just ordered my SPC900NC from JPL and a Mogg Adapter for it. Now I need to source a Filter.
Which one do I get?
From what I can gather there are two types
1. IR block filter.
2. UV/IR block filter.
If I have read this correctly a IR block filter byitself is all that is needed is you have a color free telescope (APO). Mine is a SCT and I am guessing mostly color free hence will IR block filter be sufficient. Or is this incorrect and I need the UV/IR.
Which brand is better?
And there are a few brands, Lumicon, Badder and Astronomik etc.
Are these filters useful for DSO imaging?
