The iOptron Urban MC90 "GoTo" telescope system

More Features Than The Competition But At What Price?

I believe the MC90 is actually a Maksutov Cassegrain and not a Schmidt Cassegrain optical system.

True: 90mm OTA is MCT not SCT - Really a "knock-off" of the Questar and Meade ETX-90.

True that you have to tell the computer where and when you are but really - how hard is that? As for the batteries - I have used the external jack and an older Celestron Power Tank. Yes, AA cells can be used but I have no experience with that approach. The scope will run just fine with the external power. The mount speed selection is a true PITA and the finder scope is best replaced with a red dot. I found that a wrap of pipe tape on the threads of the altitude lock made it much more secure.

I have the 70/400 refractor and if your MC90 is as good, you whould be pleased.
Hmm - cannot edit...

That should be 80/400 refractor.

I spent the extra money and got the GPS equipped Cube A or Cube G models and have not looked back. The Cube E needs time and location each and every time you power up.
