Re: Night Substitute

Too cloudy for comet again.

Yup. Professional astronomers do detailed studies of weather and other factors and have concluded that they should not install observatories where you live or where I live.

Did better than I was expecting wide-open, after some of the softness I saw in testing.

I'm seeing a lot of astigmatism and coma around the bright stars. You might try stopping down and stacking.

Regards,

Alan
