Last night (Aug 11, 2007) I redid my images of M81-82. I made more images, 60 instead of 45 and with each being at 45 sec. instead of 30 sec. of exposure. Also, these images were shot in RAW instead of JPG. I think the effort is much better than my images of Sunday night.

Location: DAO, old 16' site
Optics: Orion 100ED, f9 refractor
Camera: Nikon D50 modified
Exposure: 60 light frames at 45 sec., ISO 800
Process: Calibrated with 20 dark and 20 flats in ImagesPlus, Photoshop CS2 and Noise Ninja.
