Cheers Kevin. I'm a DSO imager... and a solar system 'hack' imager. I don't do it often enough. In fact, if my memory service me right, this is my first post in the solar system forum since joining in 2006. I will post here again in another 9 years. No guarantees you will see an improvement...
The DSO side of me is thinking its nice to some background galaxies in just 8 minutes of exposure time when in reality I should be enjoying the view of the comet.
