Just for interest here is a pic taken with the Tal at 1790mm and exactly the same area cropped from the widefield taken at 300mm. It gives an idea what is real and what is noise in the widefield.
Here is a larger picture of the tal image 2MB

Most of the dim 'stars' on the widefield seem to be real even if they are blurred compared to the Tal image dim stars. We dont want to enhance noise.
I have to do something while it is cloudy etc.
