Brian,

They are all quite good. Also, check out Televue's Nebustar which is on sale right now. I also like Thousand Oaks UHC in my 16" Starmaster.

An observing buddy and I have compared the Lumicon with the Orion in two different C-8s. We both agreed that the Lumicon offered the best views. We looked at a variety of objects, including the Veil, the North American, the Pelican, the Crab, the Orion Nebula, etc.

FWIW, we also compared these with the O-III and a couple of other light pollution filters, including the Orion. The Lumicon UHC was the clear winner. You could see a lot more detail with this one.

I would be interested in other observers' views, particularly those with larger scopes. A friend in our club has an 18" Obsession, and he can put in an O-III and get an amazingly bright view of things that are pretty dim in a C-8. The O-III blocks out a lot more light than the UHC, at least in the views I have seen.
