I shot some DSOs with the Stellacam EX (www.astrovid.com) and the C14 telescope at the Donald C. Martin Observatory on 12/30/03. There was a quarter moon off to the west so I shot to the east. For most of the images, the "sense up" was 128x, gain was at max and mode was ELC. Objects were acquired using Astrovideo. I acquired as a "fits file", 20-300 single frames were added on the fly every 2 seconds. I assume that this is integrating and not averaging. All objects were imaged through a f3 reducer that was used without a diagonal. I touched up the images by cropping and then manipulating with the curves tool or the levels tool in the freeware program GIMP.

This is NGC 891 120x2 seconds

This is NGC 891 300x2 seconds

M1 60x2 seconds

M1 300x2 seconds

M 78, 150x2seconds processed with levels

M78 reprocessed with curves rather then levels

The seeing was not so hot but I grabbed 45 seconds of  AVI video of Saturn from my SAC IVb and processed with Registax 2, these are all the same data, only the wavelets were varied. Prime focus of the C14. Quality 80%.
