Despite a lot of clear nights over the last few weeks seeing has been average or worse. I decided that hunting down a interesting dim target would be pointless! Instead I chose something bright that could be well resolved and provide some detail. After 7-8 nights I decided i better process the data :). The is a lot of data here that has worked well for the two main galaxies. However with this many subs I was hoping for more IFN. There was a lot there but it was not clean, even with nearly 200 lum subs so I did my best to resist the temptation of pushing to hard and just focused on the galaxies. These did process well despite the conditions, on review I could have probably got similar results with 1/3 data but I wanted to see if IFN would resolve under average seeing. Answer is clearly a no! Well not in a way that is clean enough to process nicely!
