Description

This is the first "real" test for the Acuter 90 900ed refractor. More than 4 hours on this couple of objects taken on the night of the 28th of March. Camera was a modded Canon 600d. Mount the Vixen GPDX - version 2 - added 180 frames of 1 minute unguided each taken on the 29th - sky was very bad with high clouds and a little fog. If someone can tell me if the image is improved or not, I would appreciate.
