I spent most of the night finishing up the tests I've been running recently. But I had some dark time left when I finished that so I got an hour of 5 minute exposures of M-101 and 50 minutes of 5 minute exposures of M-97. All shot at f/5.5, unbinned (1x1) through clear filter. Here are a couple of quick and dirty versions (I've learned not to put much time into processing as other folks on this list do much better than I can <g>): http://users.wirelessbeehive.com/~paw/temp/10197.jpg And for those who might want to try their had at working with the raw files here are the M-101 image, flat and dark files (about 59 MB): http://users.wirelessbeehive.com/~paw/temp/m101.zip I'll remove those and post the M-97 data in a day or two (not enough room on the server for both sets). Well, light is starting to shine through the curtains. Time to turn in. It's been a great night! patrick
