Craney Posted March 21 Share Posted March 21 Hello everybody, Hoping somebody might have an answer to this one. A student at the school where I teach has got himself a Celestron Astromaster Newtonian.... like the one shown below... He has had a spot of bother setting up and understanding polar alignment etc, so I have decided to help him out and lend him a few accessories. Does anybody know what the eyepiece diameter is on the focuser ? ( I would guess at 1 1/4 inch ..... but it could be a unique one-off gauge). and is the red-dot finder sat on a normal finder-shoe base that a 8x50 finder scope would fit onto. Thanks for any info. Sean. Link to comment Share on other sites More sharing options...
