Hey friend, I use a 10 inch reflector and a 5 in. refractor. I don't have dark skies at home, can hardly ever see the Milky Way here, but in a 1 hour drive it gets good. I have a club and there we use a 22 in. and I also have used the 60 in. on Mt Wilson that Eisenstein and Hubble used as well, there too not the darkest skies though! -Glenn
