I am expecting that your superior light grasp would have a great ability to use dimmer stars despite the smaller field of view. There would be trade offs but I think your system would really benefit from an AO. I take your point though. Long FL has its issues.
Wow! Thanks Paul. Perhaps it is something to investigate.
