  1. Hi all, I'm an astronewb looking for advice On the websites of many telescope vendors I see this term "Highest Useful Magnification" used and I've been wondering about how strictly to interpret that. For example, I see a scope with a focal length of 2032mm. Does this mean that I could fit it with a 2mm eyepiece and get a magnification of 1016x? I'm mainly curious about the image quality at that level. Like for the scope with the 2032mm focal length they claim a Highest Useful Magnification of 480x. Which I'm guessing means one can't get decent images with an eyepiece smaller than 4.50mm or 4.
