after shutting down the observatory because of the horrible seeing conditions, it got me thinking what FWHM do people get on average. tonight i was getting close to 6 arc seconds, horrible (i have had 9"!!!). on average i say i would get 4" (one of the main reasons i am moving the obs. the best, absolute best i have ever gotten is 2.8". i know that it is dificult to top those conditions
but i thought i would throw it out there, what do you get, average, best, worst
