Normally, when I view the screen for my ccd size showing the ccd frame,
I want to see 20th magnitude. As I zoom out there are fewer stars
showing but presently there are still too many stars showing in the
wider views. How do I change the rate at which the stars disappear as I
zoom out without changing the zoomed-in values of 20th magnitude? I use
the mouse wheel to zoom.
