lower percentage a bit longer than that. That is long enough to get some
very nice images. You can decide further down the track if you want to go on to guiding, and what method to use, and if you want a larger scope.
Actually, the ED80 is a bit aperture challenged for the visual side of things;
you could get a used 6 or 8" Newt for a few hundred bucks for visual use.
