What"s a good filter (imaging only)to help with light pollution and to get just a little more contrast from Nebulas. Especially the emission type.I don"t expect a "one size fits all", and i"ve been thinking about the Huetech IDAS. A new telescope store opened up just 10 miles from home, not sure that"s a good thing, and the owner suggested a Baader O111, and i thought there were for visual only. I will be using a 4" achro refractor, Canon 450D unmodded,in mag 4.5 skies at best, and will be guiding. Any ideas?

Thank You, Vic

Hutech IDAS LPS v2 or v3, or the Astronomik CLS-CCD are pretty hard to beat imho..
I prefer the IDAS..but have owned both and they give similar performance(REALLY good)..

Good luck
