    Default Explore Scientific 32mm LER (62º) or Skywatcher Panaview 32mm (70º)?



    Hi,

    I've just bought a 2'' Explore Scientific 32mm LER (62º) and after some test I was a bit disappointing, I fount that on the outer edges there were coma aberration. Had anyone found this problem?

    I was thinking in return it and get a 2'' Skywatcher Panaview 32mm (70º), any thoughts or suggestions?

    Thank you.
    Clear skies,

    I would say that the culprit is likely your fast Newtonian reflector, they can be finicky about the eyepiece used.

    The 70 degree Panaview I believe is an Erfle design and will be even worse than the 62 degree ES eyepiece.

    I have found the ES 68 degree eyepieces to work well in my fast Newt, but you can expect to find a small amount of edge distortion with any eyepiece in the scope.

    What would be the best eyepieces to fast Newtonian? Is there an indicator/spec that I should take into consideration?
    Thank you very much for tall the help.
