Processing: CCDAutoPilot3 used to collect data over multiple nights. Maxim DL/CCD for image acquisition, CCDStack on a x64 Vista machine for Image calibration, Astrodon LRGB filters (15 flats each L,R,G,B, Bias subtracted and Sigma Clip combined, 25 bias frames Sigma Clip combined, 25-600s darks Sigma Clip combined), alignment, normalization, FITS master files creation, and RGB raw TIFF creation.

Conditions: Good to Excellent, Mag 6-7 Skies
Scope: FSQ-106N
Camera: Apogee U16M, -20°
Comments: South mount (Sierra-Remote Observatories - ). This was Steve Mandel's OTA, camera, and mount (Paramount ME, FSQ-106N, Apogee U16M, Astrodon LRGBHaSIIOII filters and a Takometer Rotator, FS-60C guidescope, and SBIG 402 guide camera). This was taken over multiple nights. CCDAutoPilot3 put the scope right back on the target every night and all I had to do was setup the exposures. I have some Ha data I plan to add later.
