Skies were below average transparency and straight at Atlanta, GA light dome so LP was high. The noise per sub-frame exposure was 45-50 ADU RMS so I figured I needed between 50 and 60 frames to drive the noise down to the correct level. I was able to simply let the AP1200 image unattended all night long so I got 68 frames. Equipment: Telescope: Celestron C11 + Focal Reducer Mount : AP1200 Camera: SBIG ST-10XE + CFW8a + Astrodon Tru-Balance LRGB filters. Conditions: Transparency : Below average Seeing : Between 2.6 and 2.1 FWHM (4.0 to 3.1 HFD) over the course of the night. Exposures: L: 6 minutes x 66 frames (rejected two) R: 6 minutes (2x2) x 9 frames G: 6 minutes (2x2) x 9 frames B: 6 mintues (2x2) x 8 frames (rejected one) I had an additional 6 RGB frames each but they did not improve the color image when I added them.
