Exposure: | LRGB 170:75:105:75 : 17 x 600s L, 5 x 900 R,B, and 7 x 900 G |
Processing: | CCDSoftV5 for image acquisition with all exposures binned 1x1. MaxIm V4 for image calibration,(25 flats each LRGB, dark subtracted and median combined, 40 bias frames median combined, 30-600s darks median combined). Dead/hot pixel removal, alignment, normalization, color combining, unsharp on Lum using CCDSharp 3 iterations. Photoshop CS for final color balance, LRGB combine and jpg conversion. |
Conditions: | Average, Mag 3-4 Skies Clear with average transparency, seeing was poor |
Scope: | C14 @ f/6.3 |
Camera: | SBIG ST-8XE, -20°, Celestron 6.3 Reducer/Corrector |
Comments: | Taken in one session. Lum was shot on the East side and the color on the West. CCDAutoPilot captured all the color data and I went to bed. The seeing was not as good as the NGC 891 night and the wind kicked up to around 5-7 mph during the entire color run. This made the stars a bit larger than normal. |
