Re: Which H-alpha filter?

Interesting. What filter is on your Hutech 30d? Clear or astronomic ir cut? I ask because I noticed much more in the way of star halo effect with my self modded 350d "no filter replacement" than my new 1000dh with the mild ir cut, when using the ha filter. My 80ed also seemed to cause more bloat and halo than my meade sn6 reflector or a quality camera lens would.
