    Default 20mm EP for Meade Infinity 80mm



    Would someone kindly point me to decent 20mm 1.25" EP for my Meade Infinity 80mm. I'm doing the AL Galileo Observing Program and I can't exceed the required 20X power. None of my current EPs fit the bill.

    ES 68 deg 20mm is a great EP, easy to recommend.

    Gentlemen, thank you for your feedback.

    It's an f/5. I really only need this EP for this one observing program. The rest of my ES 82* EPs are well suited for this scope. As for the AFOV, I would like something wider than 52*. Budget would definitely be under $100. Half that is possible.

    Thanks Gabby. It is an interesting program.

    FYI. I was posting and 'thanking the gentlemen' while you posting at the same time. You posted before me. No slight intended.

    By the way, the 40mm GSO Plossl is only $36USD at Agena Astro though the AFOV is only 45░.
    It will still give you a TFOV of over 2░ with your telescope and a 2x barlow/ 1.25" diagonal.

    I've found some reviews (that are not exactly qualified) stating that the GSO SV 20mm goes soft at f6.

    Gabby's idea of a 40mm GSO Plossl and a 2x Barlow is nice since then you get both the extremes of the magnification allowed in the program. For half a $100 you can't expect good correction to the edges at f5 except in a 50 degree Plossl, though.

    ES 62deg 20mm is $89.99 shipped, technically under $100.

    If not, my next choice would be a good 20mm Plossl. Coincidentally, Meade 4000 is on sale at Agena

    https://agenaastro.com/meade-series-...-eyepiece.html

    I know you indicated wider FOV, but I don't see any other good options for your scope in $50 range which are exactly 20mm
