Rosette Nebula - Borg 77ED-II f4.3 & SXVR-694

After four imaging sessions in just 8 days it's the object I turned to last that has given me the most satisfaction so far... in part because I had to cut down most of a tree to capture it as it rises over a neighbours house. I then have about 2 hours before it sinks behind a neighbours tree, or at least I do now that the tree is gone :-)

The Rosette is a star forming region over 5000 light years away and is an emission nebula rather than the supernova remnant that I always think it looks like. Either way it's a beautiful object with lots of details and it fits my field of view perfectly.

I've only captured Ha so far but I've gotten 3.5 hours of it in 10 min subs.
