NGC 3628 -- Spiral Galaxy in Leo467 viewsNGC 3628, a spiral galaxy in the constellation of Leo, and one of the Leo Triplet galaxies. This image is my first CCD image from Lake Riverside. The conditions -- high wind that came up after midnight -- limited the total exposure time. Processed in Maxim DL, CCD Stack, PixInsight, and Photoshop.Apr 13, 2008

NGC 891 -- Spiral Galaxy in Andromeda935 viewsProcesses with data from December 18, 2004 and November 17 2006. 5 hours 5 minutes actual, 7 hours 20 minutes effective exposure. Processed with Maxim DL, CCDStack, and Photoshop, using GradientXterminator. Luminance combined from clear, luminance, and RGB filters unbinned. Color combines binned and unbinned sub-exposures.Dec 03, 2006

NGC 4565 -- Spiral Galaxy in Coma Berenices566 viewsNGC 4565, originally imaged on May 14, 2005 and reprocessed on October 27, 2006. Flat / dark reduction performed in Maxim DL, sub-exposures combined in CCDStack, color combine and final processing in PhotoshopOct 28, 2006

M51 -- The Whirlpool Galaxy983 viewsM51 -- The Whirlpool Galaxy in Canes Venatici, Maxim DL, CCDStack, Photoshop, Gradient Exterminator. Finally a close to acceptable processing of these data. The gradients were awful so the color is a bit strained, and I may have clipped the black level a little bit too.Jul 24, 2006

M51 -- The Whirlpool Galaxy (Processing 1)609 viewsM51 -- The Whirlpool Galaxy in Canes Vanetici, processed in CCDSoft and Photoshop. This is one of my first images with the ST-10, and it is the original processing of the data. Insufficient exposure, but still the first!Jul 24, 2006

M51 -- The Whirlpool Galaxy (Processing 2)690 viewsM51 -- The Whirlpool Galaxy in Canes Vanetici, processed in CCDSoft, CCDStack, and Photoshop using GradientXterminator. I reprocessed the image with better skills and tools and got a nicer result. Still not enough data, but better.Jul 24, 2006
