    Default ES EWF 4.7mm 82 or Vixen SLV 4mm 50?



    Has anyone compared these two? If so whats your thoughts? The ES EWF is more $$ on Amazon right now at 149.00 but has a wider view than the Vixen which is only 50 degree but is on sale for only $113.00 at the moment. Decisions decisions..

    I have the ES 4.7mm, it definitely isn't going anywhere! A good widefield EP for planets, globs, and up-close views of the moon.

    Hard to say, if you want the widefield the ES should be good. If your going for the magnification with no concern about FOV I would go for the Vixen.

    Thanks for the replies and thoughts folks. I Still can't decide. I bet this vintage double circle Vixen 5mm Ortho is sharper than them both but still want to try them all.

    The ortho should be able to put up a better image than both due to the design. The differences between the two are fairly negligible, 82 vs 45 AFOV, Vixen weights 2oz less, 20mm ER (V) to 14mm ER (ES).
    Either way you will get a good eyepiece.

    I would say the only weakness of Vixen SLV is a narrow FOV. If you will be using it on a manual mount and pushing magnification above 200x I would pick ES 82.

    I do a lot of high power observations and found that it is hard to use anything bellow 60 degree FOV on a manual mount: things move out of FOV too fast.

    If you not in a rush you can wait for Christmas sale and get ES for $100, or pick it used for the same price.

    I'll vouch for the 4.7 as well but you need a really good sky to reap it's benefits - you may want to consider the ES 6.7mm 82° EP as well.....

    Good luck

    The eye relief on this old Vixen really is not all that bad. Much better than my EDSCORP 9mm which you practically have to touch your eyeball with.
