Tool Tip for "Minimum star size at 1x1 (px) is wrong

2.5.1.15

Tool Tip for "Minimum star size at 1x1 (px) says: "Adjust the maximum number stars that Autofocus will"...

So that doesn't seem right.

What is the correct tool tip for that parameter? Is it just the ArcSec per pixel you are imaging at?

I'm currently imaging at 0.77 arcsec per pixel and a value of 2, for minimum star size (just because somebody in a post said "I would try a value of 2") seems to work OK. What would the correct value be?

Thanks

PS if it's related to arcsec per pixel, wouldn't you just derive it from the "Scale (1x1)" setting in the camera tab of the control panel?
