    Default Nexstar 4se



    Hello everyone. I have an old Nexstar 4se and I want to upgrade the optics. Any suggestions? I would appreciate any constructive feedback. Thank you.

    Hello and welcome to the forums map1953

    When you say upgrade the optics do you mean the telescope or the eyepieces?

    At this point, I am referring to the eyepieces.

    Welcome aboard
    IMHO, Plossls work great in long focal length scopes.
    What do you have now?

    What are you using? The good thing about your scope is it will work well with almost any EPs. You just mainly need to decide on how wide of a design you want to observe with.

    Are you just using the stock eyepieces at the moment?
    GSO or Vixen NPL Plossls will work well with your telescope, depending on what FOV you are looking for.
    Both are available from Astro Agena.

    I currently have a 32mm for low power, and a 13.8mm for medium power. I enjoy a wide field of view. All suggestions welcome. Thanks

    Do you know if they are plossl EPs? Is there a name on the EPs? A 32mm plossl EP will give you the widest possible field with your scope, you likely have as wide a view as you can get. You may be able to a sharper view with a better quality EP (?) or you may be able to get the same wide field with more magnification by getting a shorter length wider design EP like a 24mm 68 degree EP.

    The Explore Scientific 24mm 68°AFOV would work with your Mak and should have little to no vignetting with your telescope.
    Their 62° AFOV eyepieces would work for you also.
