Date: Aug 2nd through Aug 5th, 2012
Location: Goodyear, Arizona
Sky Quality Suburban Light Pollution - ZLM 5.2
Telescope: Explore Scientific ED127CF Refractor - 127mm f/7.5 Carbon Fiber Triplet
Mount: Astro-Physics AP900GTO CP3
Camera: SBIG ST-8300m and SBIG FW8-8300 filter wheel

Calibration & Processing: PixInsight 1.7

This was the first light image for this camera/filters/OAG setup. Image was shot as a bi-color narrowband by mapping H-Alpha to the Red Channel, OIII to the blue channel and then H-Alpha and OIII were blended at a ratio of 25%/75% to generate a synthetic green channel. Processed entirely in PixInsight. A larger image can be seen at Astrobin.

Sorry for the slow response....I was out imaging in northern Arizona for new moon and just getting caught up after my return. How about NGC 7293 for October? (aka The Helix Nebula). It's well placed early in the evening right about now through the end of October.
