Description

Finally got my hands on an ASIAIR Plus and electronic focuser and gave my first crack at it last night.  Weather was clearish, but seeing was poor.  Pair that with an almost full moon and being past most popular nebulae, I decided to go for a bright object.  NGC 2174 was high enough and far enough from the moon to offer a test the hardware out.

10 frames of Ha, OIII, and SII each, 300s, ISO 139, bin 1x1
10 dark frames, same settings
20 flat frames
20 dark flat frames
30 bias frames

I ended up losing 4 of my OIII frames to clouds, and the seeing went south for the SII so they didn't come through well, but it still gave me proof of concept.

Stacked separately in DSS, adjusted in Photoshop, removed stars with StarXterminator, curves and levels made independently.  Converted to RGB, Ha for green, OIII for blue, SII with slight Ha overlay for red.  Sharpened with Topaz DeNoise AI.  Added stars back in.  Color corrected for Hubble-ish palette.

The moon was very bright and I rushed my flat frames, so I got a pretty bad gradient going on.  Again, I just wanted to make sure everything works.  And now I know why they call it the Monkey Head!
