Does anyone know of another source? Otherwise I could buy a 2" uv/ir cut filter for my ed80 or 8"sct. Would I need another filter for astrophotography with regular camera lenses? Also is there a budget canon lens around 200mm that is acceptable for astro?

Call or email them - they get new shipments in quite regularly. You won't need any other filter, save for perhaps a light pollution suppression filter if you're shooting from suburbia. Cheap lenses generally give cheap results - coma, chromatic abberation, the list goes on and on... -------------------- Celestron CGE / C-11 (CGE-1100) Megrez 90 FD APO / 0.8x FR/FF vIII QHY8, 350D, DSI Pro, SPC900NC KWIQ Guider (QHY5) ETX-125AT 12" Lightbridge My Astrophoto Gallery Astronomical Society of Kansas City Post Extras:       Steve L newbie Reged: 04/26/07 Posts: 2 Loc: Bagley, MN Re: baader uv/ir cut filter [Re: Steve L]       #2101429 - 01/06/08 05:31 PM Edit   Reply   Quote Quick Reply   I guess I'll keep trying to reach them. I was thinking my chances of getting the filter were getting slim. If by some chance I cannot get the sensor filter from Alpine Astro and choose to make a clear filter from Edmund glass,and buy a 2"uv/ir filter for prime focus. Would I need some kind of uv/ir filter for canon lenses?

You will need a UV/IR filter if you replace the OE one with clear glass. -------------------- John Moore Corydon Ridge Observatory My CN Gallery Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 8 registered and 3 anonymous users are browsing this forum.
