I've heard the "Mars 2003" filter from sirius optic in Brissy is pretty good. they cost AUD$115.00 and I'm about to order one over the next few weeks, maybe lol. I have heard they work better than the standard colour filters but kinda combine what the seperate colour filters do.

Houghy, I'm with you on 2" filters I have a 1.25" UHC filter that I wish I could throw on the 30mm SV, I think from now on it's be 2" filters as most things you want to look at are in the WFOV low power format. But being an Astronomiks fan it wont be cheap
