| Notes: | I had some difficulties with the mount's RA-tracking, periodic error was quite high causing lot's of rejected frames. Many frames had also to be rejected due to clouds. The image shown has some banding noise that needs to be eliminated before more details from faint levels can be seen. I'm going to use Iris for this as I did with the 2.5.2004 M108-image. | ||
