Re: New images with the 140EDF refractor

The seeing in the Illinois area is not great due to the jet stream
typically being overhead :-( Typical FWHM would range from 3.0" to
3.5". A good night would be 2.5".


I have a sneaky suspicion that you also have very good seeing. Have
you sat down to estimate some kind of FWHM for your location on a
typical evening?
