• 2003-Sept-27 - HX916 image of Horsehead and Flame Nebula, (TV101 OTA on G11, 60 minute total exposure [a stack of 6 10 minute unbinned Halpha filtered images], STV guided, from LBV [seeing 3, transparency 9]). Processing: AIP (dark calibration, stacking), MaxIm DL (brightness and contrast adjustments).
• 11/05/02 - HX916 image of Horsehead Nebula (~f/5.5, Meade LX10, LRGB of 50:30:30:30 (10x5 minute unbinned L, 6x5 minute each RGB binned 2x2), STV guided, flat and dark frames applied, from OCA/Anza [seeing 7, transp 7, tracking HORRIBLE at 7.5X, 5.0Y @ 3 seconds]). Processing: AIP (flat and dark calibration, stacking), MaxIm (3 passes of histogram shaping User-Defined Transfer Function on Luminance), AIP (color registration, color balanced using G2V then Black Sky), Paintshop Pro (resized 50%). Note: The blue filter is not parfocal with the other filters and will have to be replaced.
