anyone have an ICS filter?

Dave i believe you. Every scope of every size has its own issues.

I still cant wait til the day i get a go on your (or anyone elses) 20" scope.

That will be my nirvana.

Hm... I bet his eyesight is not as sharp & crystal clear as ours, PJ! That makes even Twisted Evil he he he.
(that makes us feel comfortable, right?)
Sory Dave, I am just being a bad boy!

LMAO................Vagelis you are evil,LMAO.

Lads,
Anyone here ever used/heard of ICS O3 or h-beta filters.
I'm finding it tough to find info about them on the web.

Well if your german is good try the home web site:
www.intercon-spacetec.de/

Not too much info really and, just having a quick look, seems they do only OIII and UHC.

Yea, I'd found that but was really looking for bandpass graphs and some reviews.
