Recognizing that I'm severely limited by the equipment I'm using (saving for an APO, CCD, better mount, etc), I've been trying to extend my exposure times. Up to this point, I've been limited to about 3-4 min exposures due to skyglow. This was my first attempt to use an Optolong UHC filter to try and reduce light pollution. I'm currently using an unmodified DSLR, so I was interested in seeing how much (if any) red hydrogen I could sneak past IR filter. All the light subs were 420 seconds.
