Problem viewing planets using 25mm eye piece. which eye piece works the best? nextstar 80 slt


The smaller the number on the eyepiece the greater the magnification-- the maximum magnification of any telescope is about 50 times aperture. You scope is about 3 inches -- so 150 power is the maximum usable magnification.

BUT-- only under perfect conditions -- perfect sky-- perfect optics -- perfect eyepieces. Usually 30-40 times aperture is all you will get on a typical night with some turbulence in the atmosphere.

The lense for my Nexstar 6se was taken apart and I don't know how to put it back together properly. HELP!!


The eyepiece should NEVER BE DISASSEMBLED! Since it has multiple lenses inside no one can tell you how they go back together. This also voids the manufacturer warranty.

Go and buy another eyepiece and NEVER ever disassemble them. Only the OUTSIDE surface ever needs cleaning,

Here is one retailer who sells eyepieces.

Just got a celestron nextstar 5


You are NOT in focus. You are seeing the central obstruction in the lens on the front of the tube. Put the eyepiece with the largest number written on it into the telescope. Go outside during the daytime and practice focusing on a distant object.

Once you are focused properly you can see the obstruction.

You obviously burned out something inside. Many of these scopes require a proprietary style 12 volt plug with the correct polarity ---

My only suggestion would be to contact celestron and send it in for repair.

Be sure that the telescope is configured for EQ SOUTH mode to tell it is in the southern hemisphere. Once a star alignment is completed NEVER manually move the telescope. Use only the control panel to slew. Everytime the telescope is move by hand, the motors do not know it has been done, and assume it is still pointing at the old direction. Check the manual for setup.
