hmm good thread Geoff..
So astronomiks is the best but at almost double the price.. Orion Ultrablock is in 2nd place, not quite as good, but still good and much cheaper..
Tough call now..
Orion blocking all the h-beta line, and astronomiks letting a little through.. what will that help me to see? If it's only on a handful of objects is it worth the extra?
or.. as others have said before, buy best quality now and cry just once
