    Default GSO eyepieces ?



    Does anyone have experience with GSO eyepieces? I've heard they are quite inexpensive and offer a lot for the price. Any opinions or insight please.
    Thanks......Ray

    I have the 42mm wide view and just love it, I have only used it in my f/4.9 dob so far and the views are great, Because of the astimatism and the floaty's in my eyes, I will probably never step up to the tele-vue glass.. It seems it would be a waste on my eyes

    i have a number of gso ep's and they do perform better
    than their price suggests.
    be aware,they actually supply the likes of celestron,meade,
    orion,s/w and others,who simply rebrand them and up
    the price.
    whilst they are not high end,they are very capable ep's.
    if the name on the barrell is of no importance,then why not?
    is it worth paying 3X the price for 5% gain?
    they will not be crisp to the very edge of the fov,but to me,it
    don't matter that much,i wanna see what's in the middle.
    just my opinion fwiw,others may think differently.
    but i will say this,for the price,and a bit more,they are kinda hard
    to beat.

    Hi Raymond,

    Definitely GSO eyepieces represent excellent value for money and they are beautifully presented. I have the following:

    15mm,20mm,25mm (1.25")Super Plossls. (52deg FOV).
    20mm (1.25"), 30mm, 42mm (2") Superviews. (67deg FOV).

    Barlows; 2x,3x(ED) (1.25"), and 2x(ED) (2").

    I use all of these with a 14" f5.1 Dob.

    The following comments I will make:

    (1)The 42mm Superview gives an 8.3mm exit pupil,with an f5.1 focal ratio so you exceed the 7mm max that allows you to utilize the full aperture of your scope,ie at f5.1 only 0.84 of your aperture can be caught by the eye.

    (2)I find the 25mm Super Plossl as a great ocular for "general sweeping" due to its tight star images and when barlowed 2x or 3x is great for those planetary views. (I have other more expensive eyepieces and when "head to head" with this ocular its hard to pick the difference).

    If you go GSO you wont be disappointed. Truly value for money spent.

    Stephen. (From down under 44deg S).

    I use the 30mm 68° and really like it. It's actually my most used eyepiece.

    I agree with everyone, great value for the money. My GSO 30mm super view is my most used eyepiece.
