First Light: Canon Digital Rebel XT

A triple whammy today! My generous employer purchased a Canon Digital Rebel XT, so I got myself a t-ring to attach it to the LX200 at prime focus, and a piggyback bracket for the top of the scope.

This first shot is with the piggyback. I used a 100 mm macro @ f/2.8, 4.5 seconds x 12, unguided, ISO 800, stacked & resampled in KIS, levels & noise filtering in PS CS2. My very first DSO photograph is of Pleiades (M45). I'm rather pleased that some of the nebulosity shows up.

The second shot is at prime focus. It's a two-image mosaic, each one a single image, 1/125 sec, ISO 100. Composited in PS CS2, resampled down and sharpened, levels. The focus is off a bit--I was focusing strictly through the viewfinder. I'll try out iAstroPhoto once I get all the software installed to control the camera.
