Full Moon last night and clear skies. I set up on my roof, and took sixeen exposures in an hour: 20Gb monochrome. I am very happy using Astro IIDC for capture. ETX 125, scorpion 1.4Mp camera, focal reducer to f7.5. Conditions are a bit too extreme in Manhattan to stack the .mov, or I haven't picked the right settings, so I export the .mov files to .avi no compression. These are saved to an external drive and I reboot the mac to Windows 7 and run registax 5 to stack. Saving as tif, it's back to the mac for Photoshop. I was most interested in getting the rays well defined without blowing out Aristarchus. You can find the image in the photo album finkh.
Only the original shows the details.
1200 frames captured, 900 stacked.
To prevent over exposure when capturing, use the the "Show Saturated" checkbox on page 82 (and 71) of the Astro IIDC manual. It will show you when your exceeding a given brightness tolerance on screen.
HTH..
