I have an old Astromaster sitting in the top of a closet, which i have kept simply because it has no value to sell and perhaps i can mod it, but i don't like throwing away a scope. The Starview i have no direct experience with but from the website they look nearly the same. If they are equal in sll aspects go with the larger apeture, would be my advice. If it is a gift for a youngster then i would consider something easier to use, like a small dobsonian.
