This is my "First Light" test image with the new camera. It was taken at full moon, and is intended to give me a feel for the field size (1/2 degree) with my 12.5" newtonian. The collimation is a bit off, as illustrated by the stars in the lower left corner. Instrument: 12.5" f/5 Home made Newtonian Platform: Astrophysics 1200 QMD CCD Camera: SBIG ST8i Standard Cooling Exposure: L = 2 mins RGB Combine Ratio: Filters: NONE Location: Payson, Arizona Elevation: 5150 ft. Sky: Seeing FMHW = 2.5 arcsec, Transparency 8/10 Outside Temperature: 10 C CCD Temperature: -5 C Processing: Maxim DL, Photoshop, AIP4WIN, PW Pro.
