Inner scope??? you mean the eyepiece (s) are broken. Measure the hole eyepieces come in 3 sizes, .965, 1.25, and 2 inch sizes.

The .965 eyepieces are very difficult to find as most amateur telescopes use the 1.25 inch size.

Try Telescope Warehouse or Agena Astroproducts for a replacement eyepiece:

Don't ever buy another off brand telescope at a garage sale that you know nothing about.

I lost the manual. how does it work ??!!! i think i've lost some eyepieces as well.


This is a very simple REFLECTOR style telescope. The reviews are very bad-- see this:
http://www.amazon.com/Cstar-Stratus-UB-3700-Reflector-Telescope/dp/B00025VYO4

Simply put the eyepiece with the largest number written on it into the focuser and practice focusing during the day time on a distant object. There is no manual for this scope anywhere on the internet-- it is a very cheap low cost imported telescope.

Also the tripod is way too small and shaky.

Recently lost gun in water for a moment, Now scope gets fogged inside. Is there anything I can do to stop it? It a fairly new scope.


Your scope may not be hurt if water has not caused any rust yet. Things you will need, (1) hair drier, (2) Vaseline, (3) large clear plastic bag, (4) gas from a paint ball gun canister or similar type of inert gas you can use. Remove the eye piece, and shake as much water out as you can. Use the hair drier and heat the tube up, not too hot but warm, to dry the inside as good as you can, keep after it, shaking it and heating it. Once you feel all the water and moister are gone. Put a good amount of vaseline on the threads of the eye piece. The put the scope, the eye piece in the plastic bag. Use the paint ball gas and inflate the plastic bag, tie off the bag leaving room so you can screw the eye piece back on the main tube. Leave the scope in the bag for a few minutes before you do screw the eye piece on letting the gas fully get in the tube. The gas will give a bit of positive pressure inside the tube, Will displace any other air that will have moister in it. Keep the inside from fogging back up. The vaseline will help seal the gas inside. Hope this Helps Fix Ya up.

The DIAGONAL is what it is called. Look here:

Diagonals come in 3 sizes -- measure the hole in the focuser .965, 1.25 and 2 inch sizes.

Buy the correct size.

There is moisture trapped between the lenses. I took eye piece off to let air in but it didn't help. The moisture is actually trapped between the two pieces of glass in lense.


Hi Rebecca,
This is something that Leica will need to repair for you, as they are the only ones who have the tooling and parts to get inside of your scope. If you are in North America, you can contact them at 1-800-222-0118. Seeing as how the scope is supposed to be waterproof and nitrogen purged, I would suspect that any repair service is covered under your scope's lifetime warranty.
Best Regards,
Ben

I got a beautiful scope in a estate sale but it seems as the end with the cap is on the wrong side it is right next to the eye piece? Also the elbo for the eye piece is missing can I get one?


The larger end is pointed UP, the diagonal and eyepiece go into the smaller end of the tube. Measure the hole, these come in .965, 1.25 and 2 inch sizes.

Many on line retailers sell these. Here is one retailer:

a diagonal check the size of the hole:

Cstar 700 reflector telescope bought a floor model at a discount. Need tips on assembly


You won't find a manual for those small telescopes. However Meade maintains a site with their manuals. Find one similar to your scope under REFLECTORS and download the manual.

Missing the eye piece for the Meade saturn 60az-m


ebay is a great resource for eyepieces, i would suggest a 26mm ma.
the eyepiece should drop in. if not you might be missing the image erecting diagonal. when the eyepiece is installed you should be looking perpendicular at the tube.
