One image is slightly above the other at all distances. After using the binoculars for even a couple of moments, my eyes are strained. The problem was present when the binoculars were purchased, however...

The oculars are not aligned properly causing double vision. Check on the binoculars to see if there is a place to adjust the alignment of either of the oculars. Look for any loose screws that may cause the two oculars to be out of alignment.
If this is not the case try adding some torque to the binoculars to see if the will adjust to where they will both point in the same direction. The eyes can fuse disparate images slightly but there is a very small range that they can handle. If the two images are separated by more than this small amount it will cause eye strain and double vision.

Trying to use the telescope but cant see anything

Hi, this is a real handy scope. You need to remove the disk like cover for the high polished mirror located at the but end of the scope. Then insert one of the two ocular lenses provided into the viewing aperture. Next, aim the polished mirror end at something obvious like a street light. Use the range finder located opposite the viewing aperture, (switch red button on) and align the circles with the red dot. Happy viewing!

My premiere microscope MS-01 Ultra will not focus

There is what is called a "stage stop" screw. Its purpose is to limit the specimen from rising high enough to contact the objective lens. The "stage stop" screw is directly behind the black stage platform in plain sight and very easy to access. It is a thumb screw and sits vertically. Simply loosen it a bit to allow the specimen to rise high enough to focus.

I own a MRJ-03 Premiere microscope with the a bad electric board. How can I get spare parts for it? abnernm@hotmail.com

I have the same problem and can't find parts anywhere. Premiere Microscopes doesn't answer their phone or return calls and their customer service email keeps rejecting everything I send. Please let me know too if there are parts available for this microscope.
