Seeing Ant. III
LMag. 4.5
Filter: This takes a bit of explanation. A UHC-S is a high pass filter for essentially reddish, blue-greenish, and greenish light. So I took a gamble that as reflection nebulae scatter blue light most effectively, that I might get some contrast improvement using the UHC-S. For my eyes, the UHC-S did improve contrast. Equally this could be due to suppression of other stray (sodium glow et. al.) light.
