If my average mag skies are 4.3 (Zeta Lyrae) or perhaps a little
better, might I benefit from a UHC filter? I'm thinking about getting
one of these-an Astronomiks, but have read ultimately they work best
at dark sky sites-not hard to believe.


Hi Kerry,

My UHC filter is also an Astronomiks. I don't really use it too much but =

once i a while on planetaries and things like the Veil it's quite =
helpful.
My backyard skies are around a Bortle class 6...

I only tried the UHC the other night just to see what kind of difference
it would make. I generally perfer the few without the filter.=20
