for a beginner such as myself there were things mentioned in the instructions which make sense to me now, but none when i first started. I gave ease of use 6 mainly because of the instructions given by meade. i have since modified it a little, and it has improved that somewhat. I gave the mount a 7 because it shakes at high power.
it has textbook images of stars (much better than the lx200)its only drawback being its 3.5" aperture. I gave the optics a 9 because i'm not sure what a 10 is.
i have since upgraded the autostar twice and it is almost like getting a new telescope. I now also own a 10" lx 200 and the etx will slew anywhere the lx200 will, i may not be able to see the object but it is there in the same location. aside from the instructions that meade supplys with the scope, leaving somewhat to be desired, i am completely satisfied with it. Hopefully the bugs are fixed, but for my money, I'll stick with an Orion StarMax. The wife and I tracked down 15 Messier objects that night and had a hoot! Mine was one of the first EC models. But honestly, the best time I had with it was when I pulled the OTA out of the forks, and mounted to a camera tripod. In polar mode, using the scope manually, it was okay. The electronics were wonky, 60% of the time, the scope would not complete it's 2 star alignment. The problem with mine was everything else with the scope. Deep sky is possible with this little monster - M81/82 are easily viewable with details! Ring nebulae shows very well. Pumping up the power to 200x is easy, and M13 really resolves well - very similar to my old C8 (but just a lot dimmer). M13 is granular with edge stars easily resolved. Star tests are excellent, splitting Eps Lyrae is child's play. The 3.5 inch Mak OTA is awesome, the views razor sharp.
