I have to use it in 2" mode with my Antares 2" mirror diagonal, because it doesn't come to focus in 1.25" mode with the supplied 1.25" to 2" adapter (not enough in-travel). But that's ok. The views are really nice, and the lack of kidney-beaning means it's fun to use during the daytime too. At night, stars remain pinpoints to the edge, I don't even get much field curvature. -------------------- Jonathan Hoof 15" F/4.14 Discovery Truss 8" F/5.9 Orion XT8i 6" F/6 Intes-Micro MN66 4.5" F/4 Orion Starblast 80mm F/7.5 Orion 80ED 18x50 IS Canon binoculars Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 24 registered and 13 anonymous users are browsing this forum.
