    Default Possibly adding to my 2" EP collection - hoping to hear thoughts on a few EPs



    My scope came with a 2" 28mm 56° EP which provides nice immersion when viewing DSOs (as compared to previously used 1.25" EPs). As a result, I'm thinking about adding a single (better) 2" EP in the future. I know the ES line is a great place to start looking, as are the Celestron Luminos 2" 82°s and Meade Series 5000 Mega Wide 2" 100°s.... but they're all $200+ per EP.

    Has anyone had any experience with the following lines of 2" EPs:
    - Orion Q70° ($76)
    - High Point Super View 65° ($70)
    - Williams Optics 72° ($118)
    - Olivion Super Wide 80° ($129)

    I'm expecting to hear that on my fast scope, I'll have issues at the edges with some of the less expensive EPs... but I wanted to hear from anyone who has had first hand experience with them. I'd love to be able to return to a large 2+° TFoV again soon.
    Thanks in advance and clear skies!

    With the Meade 5000 series I would take a good look at the UWA (82*). As Leveye said Russell Optics are well worth consideration.

    I find there's a big difference in feel between the 68 degree and 80 degree eyepieces. With the 68 ( and presumably the 72 degree ones as well, you still have an obvious circle on a black background. The circle is noticeably bigger and nicer, but the background is still obvious. With the 80 degree and up models the circle is big enough that it more or less fills your vision when you're looking at the center, and the background becomes far less obvious, which makes for more immersive views.

    The cheapest 2" 80 degree eyepiece I have is a chinese built 30mm 80 degree one - mine was branded moonfish, but I've same the same one advertised elsewhere. cost was around 100-120 euros last time I looked; I think I paid around £80 for mine quite a few years back. In a slow scope like an f10 SCT, it works fine with just a tiny bit of softness at the extreme edge. As you go faster, the distortion gets worse and moves further in, but the central part remains fine. In a really fast (f2.8) scope stars round the edges turned into giant seagull arcs, but the central 60 degrees or so remained OK. So not ideal for fast scopes, but a fraction of the cost of the better perfomers.

    I also have an ancient 2" Meade SWA 40mm at around 68 degree AFOV - It makes a great finder eyepiece; I tend to prefer it over the 80+ degree 30mm ish eyepieces for locating things, since the 68 degree AFOV is small enough to take the whole field in at once - as opposed to the 80+ degree ones where I have to look around. Being able to see the whole field at the same time makes sweeping for things easier, I think.

    Apparently, it has to do with field curvature. The Q70 and W70 expect a positive field curvature, whereas Newts have a negative field curvature. I am paraphrasing a post I read here a week or two ago.

    What I do know is that my W70s have absolutely terrible distortion around the edge of the FOV, and that a coma corrector reduces but does not remove the distortion.

    Also without actual experience my research mirrors Keith's which caused me to rule them out.

    I have an Agena SWA 38mm that so far is impressing me in a big way. It's 70* but I don't see it a limitation, at that focal length anyway and in a refractor.

    I can't speak for the Olivion (never tried that one but would be skeptical) but the other three will show field curvature. Of the three, the High Point SV performed the best on the faster scopes.

    I can second the recommendation on the Meade 82 degree eyepieces. I have the ES 82-18 and it is a nice eyepiece as well. With experiences I have had with the 1.25 inch Superviews, they work well down to f/6 for sure. Probably f/5 is about their limit. I find those to be nice eyepieces as well, but not in the same league as the Meade and ES 82 eyepieces.

    If you can afford go for ES 82 line. They perform way above all other options listed.

    On a budget I would go with High Point/GSO SuperView.

    From what I hear Q70 and Luminos don't perform well in fast reflectors.
