Notes: This is a Ha-LLRGB image which shows the red H-alpha regions surrounding M31. Lots of processing on this image as integrating Ha data with LLRGB is more complicated than I thought. Just for fun, I've also included a widescreen version for those with widescreen monitors.

Techno Stuff: 9/10/07 Camera: ATK-16hr, Imaging Scope: Megrez 80mm APO at F/6, mounted on LX90 8" SCT, IR 65 min total with 5 min subs, no binning, Red 25 min with 5 min subs, Blue 30 min with 6 min subs, Binning 2X2, Synthetic Green channel, Autoguided with Q-Guide and PHDGuide from LX90, No Darks, Processed with CCDStack, Photoshop CS2 and PixInsight

Notes: This is an LLRGB image using a synthetic green channel. It was taken under murky conditions with high altitude clouds forcing me to keep the exposure time down. The RGB color required a heavy saturation boost plus LLRGB layering in order to realize much color at all.
