I purchased this scope in order to get "all rounder" scope for visual & astrophotography which will be portable and stable on EQ6R mount. All point's checked with this one. I had opportunity to try it the same day (night) I received it (really unique situation considering that once you buy something astro related, you usually get at least week of cloudy weather :) and apart of few things I am amazed. Scope came with strehl 0.992 primary and really, details on moon were breathtaking. Even without coma corrector the views of night sky were nice with wide angle 20mm omegon eyepiece. Only outer field of view was affected with coma, which is of course part of the fast (f4.5) Newtonian telescope design. I found only few things that could be better in this price range. 1st the spider. It's basic one, it was working fine and hold collimation stable through the night, but it's not that stiff as I would expect. You'll find it a bit wobbly when collimating the secondary mirror. I immediately changed the collimation screws for 35mm m4 bob knobs, which are making collimation easier, but you need to count with the flexing spider when tightening the knobs. 2nd the knobs on primary cell...I would say that these could be done with knurled knobs so the collimation could be tool less process. Otherwise the mirror cell is very fine, holding the mirror on place, good job on this one. And lastly 3rd. the focused. It's by no means good one, nicely supporting DSLR or eyepieces, but mine came with somehow very stiff eyepiece locking screw...this will probably get better by wearing it out by usage :) Overall really good all round telescope with few glitches which can be healed :)
