Patrick see my preliminary processing of both of your images. M63 http://www.slas.us/gallery2/main.php?g2_itemId=3247 M57 http://www.slas.us/gallery2/main.php?g2_itemId=3250 Click on the images to get the full size version. Note the dark line in the lower part of M63. This is a real feature as can be seen on other images of the object.

No time tonight to process so will do that later. But in the mean time if anyone would care to download and process, you'll find the raw data and master flat and dark here: http://users.wirelessbeehive.com/~paw/temp/M63.ZIP http://users.wirelessbeehive.com/~paw/temp/M57.ZIP Each ZIP file is about 36 MB so I can't leave them on the server very long. So grab them soon or they'll be gone.
