Date: September 8, 2001
Exposure: RRGB : 8 x 300s R, 8 x 300s G, 8 x 360s B
Processing: MaxIm for DDP and color combine, CCDSharp (1 iteration of each individual layer), Stretch, PMView for color balance, Photoshop 5.5 for JPG web conversion
Conditions: Good clear night, Mag 4 Skies
Scope: Vixen 102mm Flourite, f/6.5, 2.288 arcsec/pix measured with TheSky
Camera: SBIG ST-237A, -10°, Vixen 6.3 Focal Reducer
Comments: Tracking was good by the ST-4 through my CR-150 @ f/8. I took all the Blue first (closest to the meridian), then the Green, and then the Red. The RRGB technique seemed to work best for this nebula.
