We got an Atik CCD! Woohoo! It’s a 383+, with an 8.3 megapixel 22mm diagonal Kodak chip. Here is a picture of M61, luminance. Stacked in Maxim from 30 x 1 min pics binned 3x3 (9 pixels read out as 1 for extra sensitivity) with the camera at -10deg C. I’ve processed it so you can see all those extra faint outer spiral arms and galaxies around it. I was struggling to combine the 2 x 1 minute Red Green and Blue exposures with the Luminance – the result is below, detrailed a little. Now we’re just fighting against tracking errors and light pollution!
