Have an SV 80 ED f/7 with an SV 110EDf/7 on the way. Was considering an SV 127 but may go smaller with an SV 60 ED before they disappear.

While my 1st scope was a 60mm f/8 refractor, I consider such aperture too small for astro views even on the Moon due to insufficient light grasp and resolution. Your 80mm should be example enough to decide, will you really be satisfied with LESS resolution and light grasp? If you intend to use it for birding or Daytime terrestrial use, that is something different. I now use 60mm as finders on 6" and 10" reflectors and am considering going to 80mm for finder use; my backyard sky in a town of 16K pop. barely reveals the Milky Way as a misty glow but 2 or 3 miles out in the country reveals the Milky Way in all its' naked-eye structural glory. In rural Kansas 60mm will reveal the Veil Nebula for example, but barely so which is adequate for finder use in my estimation and no more (unless one just wanted to claim he saw it with such small aperture). For transportation by car or with stairs at home, a 6" f/8 reflector (even GEM mounted) is easily as portable as a 60mm refractor yet reveals so much more on the Moon, planets, and deep sky or close double stars (even by a handicapped individual like me).
