    Default Setting circle



    So the 127EQ has these setting circles. I see some stuff in the manual, but are they important while I'm learning to use the thing?
    I notice one of them spins freely, I thought that was odd.

    I would not worry about them to much, starhopping is a good skill to learn when starting out.
    The setting circles can be learned but they tend not to be overly accurate on some of these mounts.

    Gabby makes an excellent point. Setting circles on small mounts really aren't that accurate. It's much easier and more rewarding to learn how to star hop. With a little practice star hop becomes second natural. It can be done manually or with a hand controller. At some point every astronomer is going to have to have to learn to read a star atlas. The Pocket Sky Atlas is an excellent beginner atlas to start with. Learn in the beginning and you'll have a solid foundation to build upon.

    These days, my friend, the circles, of our entry-level kits at least, are no more functional than decorations...

    I have both an EQ-1 like your own, not the "PowerSeeker" but the "AstroMaster", and a Meade "Polaris" EQ-2...

    ...and I haven't the slightest expectation of utilising their circles.

    Your telescope is a loose simulation of a Jones-Bird telescope, a catadioptric(mirrors and lenses combined) developed back in the mid-20th century. A true Jones-Bird is quite rare. The simulations, like your own, are rather difficult to collimate, compared to a traditional Newtonian. If and when you feel the need to collimate it, and for sharp, pleasing images, you can research how to do so by searching online with the phrase "Bird Jones collimation" entered into your favourite search engine.
