Equatorial mounts

Posted By James Cunningham

I just purchased a goto scope with an equatorial mount. I have read the instructions but haven't a clue how to do a polar align. Can someone give me DETAILED instructions on how to do a polar align. I was dismayed that when I pressed the "up" arrow, the scope slewed sideways and when I pressed one of the side arrows, the scope up!

Celestron 150 goto focuser

Posted By James Cunningham

I just purchased a 150mm goto scope with a hard plastic focuser. I have heard that the focuser can be smoothed out or replaced with a Moonlite. I don't want to spend the money on a moonlite so I want to try to do something myself to get it smoother. To take off the focuser, do you just unscrew the 3 screws on the focuser itself and then just pull it off? Or is it more complicated. I have heard of collimating the focuser. How do you do that? I plan to get rid of the grease that Celestron put on it and put in some better grease (super lube) to get it smoother. Any other suggestions? Thanks.

If I get Polaris centered in the eyepiece, can I use Polaris as my first alignment star?
