It was forecast to be sunny yesterday morning but we had a tight time constraint due to other commitments in the day. Meteoblue and Skippy were predicting poor seeing and it was a gusty northerly wind. We set up early but this meant we had to use our light weight portable mount at a different position in the yard as the sun would take an hour more to reach our normal location. To our surprise the SSM showed the best seeing we have had for ages - average 1.3 arc seconds with a standard deviation of 0.4. We were not really able to take advantage of this as the light weight mount is limited to which scopes we can use and we didn't have much time anyway.
We did a Ha 2 panel mosaic. For some reason this was just "off". We are not sure exactly what we did wrong except rushing
Next we did a single panel full disk at 393nm imaged with the 72ED and ASI178MM.
Finally before we had to leave, we put in a 2.5x barlow and took a 6 panel mosaic in 393nm.
MS ICE wasn't having a bar of stitching these images so we did them manually in GIMP. They are not perfect but close.
It is interesting to compare the two versions.
