NGC 7635 AKA Bubble Nebula, Const: Cassiopeia, Type: Emission Nebula, Mag: 11.0, Size 15'x8'

• 2004-Jan-26 - HX916 image of NGC 7635 (Meade LX10 OTA at ~f/4.6 on G11, HaRGB of 120 minutes unbinned Halpha (12x10) mostly from the back yard, 55 minutes each RGB (3x10 minutes from Anza + 5x5 minutes from LBV) all binned 2x2, STV guided, dark frames applied). Processing: AIP (dark calibration, stacking, gradient correction, background equalization), MaxIm (background flattening) .
  
• 2003-Sept-21 - HX916 image of NGC 7635 (Meade LX10 OTA at ~f/4.6 on G11, LRGB of 30 minutes Halpha luminance (3x10 minutes unbinned) and 25 minutes each RGB (5x5 minutes binned 2x2), STV guided, dark frames applied, all images from Anza). Processing: I did my standard LRGB processing and then Pat Knoll did some additional work in PhotoShop. This will do until I get smoother Halpha images.
  
• 2003-Aug-23 - HX916 image of NGC 7635 (Meade LX10 OTA at ~f/4.6 on G11, 30 minutes total exposure [a stack of 3 unbinned 10 minute images with H-alpha filter], STV guided, dark frames applied, from Little Blair Valley [seeing 5, transparency 4 (intermittent clouds)]). Processing: AIP (dark calibration and stacking), MaxIm (DDP - FFT Low Pass, Medium), PaintShop (cropped).
  
• 2002-Aug-12 - HX916 image of NGC 7635 (f/5.2, 16 minutes total exposure [a stack of 8 2 minute images], STV guided, binned 2x2, dark and flat frames applied, performed a log contrast stretch in AIP, from Anza (OCA) [seeing 6, transparency 6, tracking 1.5X, 0.8Y @ 1 sec]).
