Hi niko,

I don't have any form of tracking so I am limited to bright objects like planets and moon. I have been using a webcam to record video clips as the planet drifts through the view of the scope. When the planet exits the view I nudge the Dob a little and start another clip when the planet appears in the view again.

After capturing a number of video clips I stack the individual frames in Registax to get the images you see.

Mike (iceman) has written a great article on astrophotography with a Dob in the 'projects and articles' section of the website:

He also wrote another great article on processing planetary images:

That's just my fancy term for what everyone else calls a barndoor mount for when I want to do widefield shots of the sky with my digital camera.
