After putting this scope through its paces for a few years, I can say with certainty that this is a fun, reliable, powerful scope. The optics are excellent. It holds collimation for a year at a time easily. The computer works perfectly. In alt-az mode, the three star alignment on any stars is simplicity. The Go-To's put the target in or near the center of a 9mm eyepiece. The tripod is robust, to say the least. Mounting the OTA on the tripod is simplified with the guiding pin on the tripod. The captive finger screws that secure the OTA to the tripod are surprisingly convenient. There are lots of neat details about this scope that I won't mention here you'll have fun finding them yourself when you buy one. I have used this scope for astrophotography, on a wedge, with all sorts of heavy stuff mounted over and under the OTA. The drive motors haul all the gear around effortlessly. Nit-picking: the power indicating LED is too bright and is positioned right in your face. I use the finder scope's lens cap to cover the LED. Some kind of liquid dripped off the primary's baffle tube and onto the secondary mirror (might be grease?. It was easy enough to clean. After a year of use, there developed a teeny tiny bit of mirror flop when focusing, but it's barely noticeable. Summary: You might find another scope that costs less than this scope, but you get what you pay for with this scope. This is a well engineered, carefully thought out, fun, easy to use, reliable, and powerful scope. I recommend it, or one of its siblings, to anyone looking for a scope that is a cut above the rest.
