Description

...never thought I would shoot the Cocoon in mid november! :-) Everything went fine this night, good seeing and I checked and adjusted the focus every 30 minutes. The total exposure time was limited by the object's low altitude after 3.5 hours of guiding. Unfortunately, I had to discard the subframes of the last hour, contrast deteriorated to much.
