Title: Theophilus on Saturday
Post by: MarkS on Feb 03, 2009, 07:20:28

Here's one from Saturday:

Eyepiece projection using Canon EOS350D on the Celestron C11.
25 frames of 0.3sec stacked and deconvolved.

The seeing wasn't quite so good on Saturday.  You'll also notice the image becomes less sharp away from the centre.  Trouble is, eyepiece projection doesn't give a very flat field.
