This is my second telescope set, like it over all. The OTA optics is very good, GPS engaged in few seconds, goto is almost perfect. It allowed me taking picture at the Jupiter for 30s exposure at no obviuse drift. Wish the tripod was stronger.

An average telescope at best. For a very casual user, I found the instructions accompanying the telescope to be virtually worthless. Focusing is a difficult procedure, and the tripod is barely adequate for the task. The GPS version of the finder/drive is hard to use, but I am hopeful that I will eventually be able to find a particular star without having the telescope seeking my feet. It is somewhat amusing to watch the telescope move by itself, stalking an elusive star, but doesn't seem to have any better sense of direction than my 96 year old mother. I don't have a clue how to determine if the software needs to be updated, the update software wouldn't install on my PC, so I'm not sure that there is any advantage to the machine having a USB port at all. The tripod is not tall enough for me, so almost any viewing angle is an uncomfortable exercise. I had a refracting telescope many years ago, and this one is better in many ways than the first. If you expect an easy setup and pleasant viewing experience, then I'd advise you to look elsewhere. The GPS star finder gives the illusion of simplicity that it doesn't deliver on. The telescope provided a crisp view of the moon's terminator, but just breathing on the telescope made for some shaky viewing. Haven't figured out how to lock the tube in it's mounting repeatably so that it doesn't drop out of viewing position unexpectedly. Good luck to you, if you buy one!

      I bought this for my adult son. It is the first time I've ever used a telescope to look at the sky. We agree that it is a pretty good scope for the price. We like the GPS tracking although we haven't been able to get it to properly "lock in" without manual adjustments. I would like to get an electronic focus but one is not available from iOptron (yet). High magnifications are hard to focus because jitteriness you get just from touching the focus knob.

      The manual that comes with the unit is confusing as it is not specifically for the model I bought. The online manual that you can download is extremely good. Save some time and download the manual.

      Comments about iOptron SmartStar G MC90 GoTo GPS Maksutov Cassegrain Telescope:

      Well when I got it, I was surprised at how solid it was and what it came with. I am new to astronomy and for me, it had everything I needed to get started. I haven't really had the chance to use it much due to it being summer in Central Florida and it being cloudy/hazy all the time.

      I have used it to look at the moon when it actually is visible though, and it was easy to find. But, the hardest part is most definitely trying to center it on a target. Like I said, I'm new so it is sort of a learning curve for me.

      My number one biggest complaint over all are the lenses. They work great, that's not the problem. The problem is that to actually look through the scope, I have to hold my eye open like I'm putting in a contact lense because my eyelashes get in the way. I can't stand that. Now, I did say focusing was hard, but I will admit that, the haze could have been throwing off my view a bit, so I'm not quite sure.

      Lastly, one thing that I still am not really sure about is how the GPS works. When it says it's getting a signal, it's to my knowledge that I should just be able to turn it on and it points right to any object in the sky, but I also have to align it to a sky object which throws me off a bit.

      All in all I would recommend this scope, it is very solid and comes with a lot. Again, my only and major complaint are the lenses and focusing.
