    Default Mystery part on equatorial mount



    I'm new, so don't laugh. I just dusted off my Celestron 4.5" Newtonian that's been collecting dust for about 20 years. I never really used it appropriately when I got it, and so lost interest.

    There is a small metal "thingy" on the mount that seems to have no purpose. I will try to attach a photo that I found online. Can anyone identify it for me?

    Thanks for the help!

    Welcome to the forum. That was for the aftermarket tracking motor.

    Hello Motes_Art,

    Well, more information would be helpful. I am assuming you don't have an owner's manual?
    Can you supply a model number from the scope?

    Thanks.

    Sorry, I see an answer already.
    Jan 2014, an old Celestron Firstscope 114 reflector followed me home from the thrift store, in serious need of care & repair...That started an addiction of sorts. My most recent purchase: A 12" F5 steel tube, beater Dob.
    In between, I bought...more...stuff. Errors using my beaters seems less painful. With luck, I would like to push some glass soon. I have the requirements in hand now. An observatory would be the best change if I could somehow manage it. As for me: "Getting old sucks."

    Mark hit it on the head.

    Those old tracking motors were an erector-set, but they worked... kinda.

    Thanks, Pitter. I plan on purchasing a motor, but I don't know what model I've got.

    Orion sells motors that will fit that mount as well.

    Don't knock yourself out trying to find one of those old drives. They are hard to come by. A better option is a Celestron RA drive. Depending on your mount, you may need to drill a hole to secure it, but they work great.

    AstroMaster/PowerSeeker Motor Drive [item # 93514]

    Is the mount in your picture actually your rig? If so, that is an EQ1 mount.

    Thanks for the info guys. I figured it was probably for the motor. I plan on purchasing one soon, but I don't know which model I've got. It's a 4.5", 910mm focal length on a very heavy black tripod with equatorial mount. There doesn't seem to be any kind of serial number or model number anywhere on it. Could it be a FirstScope or PowerSeeker? I do not have the manual.

    Also, it says it is an f/1, but I don't understand that. If you do the math, it should be f/8 focal ratio.

    My early 90's Celestron Firstscope 114 also incorrectly says f/1 instead of f/8, so you probably have the same scope. If so that will be an EQ2 mount.

    Mine is currently riding a CG4 mount
