Lens Fogging Issue


Apparently this is NOT a waterproof rifle scope. I would return it as you will have this same problem only worse out in the field. Buy a waterproof nitrogen filled rifle scope.

I have an issue on my meade ET90 AT. I have a motor failure message after the telescope try to find a star. Now when I turn on I received a message from the autostar to press 0 or mode in both case it start the test motor and appear the message Motor fault. I change the batteries but it doesn't change the result. When I turn on and I received the message "0 or press mode" if I try to push the arrows button the telescope move right and left but no up and down. I called the meade customer service and after 30 seconds they told me to bring the telescope to their repair center. Thanks


Try this.1. Do a RESET on the hand controller.2. Reenter your Site, Date, and Time.3. Calibrate MotorsNow see if that fixed it. If not it will need to be returned to Meade because a gear or circuit is broken inside the scope.

Hello, I have Bushnell Northstar 78-8831 telescope which I got from United States (New York) last year. Since the very first day, I am not able to get the option of "Align Start 1" After selecting Align Earth option, it directly goes to "Align start2". As a result, I am not able to align the planetary positions and manually align the telescope everytime. Can you please advise? Regards, Gaurav


This can be caused by many things-- such as dirt or grease on the encoders inside or a slipping clutch. I know you just bought this telescope, but Bushnell is NOT KNOWN for having quality telescopes.To get the goto to work everything must be according to the manual.The tripod needs to be perfectly level-- time, date, and site must be accurate, and the alignment objects must each be centered in the eyepiece. Sounds like you also have electronic issues with the hand controller. Only Bushnell can repair this scope.

There is a tiny setscrew on this side of the focus knob. Make sure it is tight or the knob will just spin around the shaft.
