that is a crazy result for 1 second subs, what would you need for narrowband, 6 seconds??
would like to see what an actual sub looks like.

im guessing M51 is pretty bright but still. With 1 second respectable deep space images are we going to see a time where a large goto dob with 20 second subs will be fine for narrow band?
