Eighteen ST-10 8 min subs, total = 144 mins. SBIG research grade luminance filter used on each sub. Subs median combined in sets of three in Maxim. 100 iterate PC deconvolution performed on each median. Deconvolved medians averaged in Maxim. DDP/sharpening applied in CCDStack on average

Six XCM subs, each 10 mins long, Luminance filter in front of XCM. Calibrated in CCDOps, color converted in Maxim and median combined in two sets of three. Sum of medians DDPed in Maxim, 100%, saturation increased, saved as 16-bit TIFF for colorizing file. Luminance/color files registered in Registar. LRGB assembled in Corel's Photopaint 12 using LAB
