Description

As gathering the data from the last M82 image, I thought it was a good idea to go for a mosaic. Unfortunately, the undistorted images overlap was too small to get it together with PI. So I decided to process the M81 image seperately and match it as good as possible in Photoshop (which I don't understand yet). Despite the obvious color difference of the background of the two panels I decided to give it a try here.
The M81 data is the result of only one night with 14x180" R, 14x180"G, 12x180" B and 25x180" L. I added the Ha-data of the last year too. Now the bad weather will stay for a while :-(
As this is my first attempt to try a mosaic I hope you like it anyway.
CS!
