Image scale???
Quick question.
I keep reading posts which refer to "image scale". What exactly is that???
Also ... for folks with scopes of shorter focal length like mine ie 8 inch f5 ... now is the time to start turning those towards Mars. What was disappinting a week or so ago ... is now a joy!!!
great views around 3am this morn. Try a 10ml EP with a 2x barlow.
Cheers
