    Default Eyepiece or scope?



    Ok, since I have a reflector I thought I would post this question here.

    I know that EP's have their limits, especially the cheaper ones, and I know scopes have their limits.

    When you are looking through your scope, is there a way to tell if you are reaching the EP's limits or the scopes limits?

    I was thinking about this last night, and thought I would ask...for my own curiousity.

    Thanks,

    Andrew

    hi andrew,
    from my experience,you know when you're reaching the limits
    of one or both when you can no longer hit the sweet spot with the focuser,
    say with a 4mm ep in my 130 scope.
    clear skies,
    andy

    So, Andy would you say that the 4mm EP has reached it's limits or is it the scope? If you were to switch to a better ep would that solve the problem?(not to put down your ep)

    I have the stock EP's(see pic ) there is no name on them and I have my doubts as to their quality, but I think that right now these are my weakest point. Not that I expect to see Hubble quality when I get new EP's...just wondering if it was more scope or EP?...or maybe the old eyes

    Depends on the seeing of the night also you realize right?
    Regardless of the eyepiece remember that a scopes mag is determined by its aperture, figure 35-40X per inch to be the average on any eyepiece.
    Even a $500 nagler is useless on a bad seeing night.
    On a 114mm scope with a central obstruction figure about 140X-180X tops. That's my guess depending on the seeing again as I said.

    Thanks for the info guys. Anyone have a guess as to the name of the eyepieces I posted in the pic? Are they bottom of the line as I expect?
