I recently purchased a 12 nm oxygen OIII CCD filter, so now I can fully do bicolor (h-alpha + OIII) shooting. The first object for such capturing was Eskimo, a bright planetary nebula in Gemini.
Equipment:
-telescope Meade LX85 8″ f/5
-Baader MPCC
-filter Optolong H-alpha 12 nm (358 х 5с)
-filter OIII CCD 12 nm (588 х 2 с)
-camera QHY5III178m
Software: PIPP (calibration), Autostakkert (stacking).
Location: Russia, Anapa, backyard.
Scale 50%.

I have tried to improve telescopes and practiced continually to see with them. These instruments have play’d me so many tricks that I have at last found them out in many of their humours.
