    Default Help choosing an eyepiece



    Im about to order a 2" diagonal and eyepiece and am wondering which brand to go with. OPT has some sales going on and these are the two I'm looking at. I would imagine the explorer scientific is better because of the original price but how much it's reduced makes me wonder if there is a reason its on sale for that much. If you have time check them out and give me your thoughts.

    Thanks,
    Craig

    Though eyepieces are a personal choice, I do own the ES 100 20mm along with the ES 100 9mm and the ES 82 30mm. All three are excellent EP's and the 20mm is probably the one I use the most. Its a really, really good EP in my opinion. I have a friend that likes to observe with me quite frequently and he also says the 20mm is favorite out of the three.

    I have the Celestron Luminos 23 mm and I use it a lot with my C-9.25 and I'm very happy with it. I have looked through the E/S 20 mm, it a good eyepiece too. I like the Celestron better. They are both the size of a hand grenade, so make sure your focuser and diagonal are up to it. I also have one of these in a 10 mm and really like it too and it's $50 bucks less Used Baader 21mm Hyperion Modular Eyepiece - 1.25"/ 2" - OPT Telescopes

    agree with rcagle44. I have the 20mm ES100*...and absolutely love it. They've been on sale for $299 for awhile. And that's about $200 less then their initial cost. They are fantastic eyepieces, well worth every cent. I have the 20 & 14 ES with the 9mm on the way. I also have the 17 Ethos (Televue 100*), and it is even a bit better (not much, but a tiny bit), but it's also more then twice the cost of the ES. The ES100 will also eat the 23mm Luminos for lunch (though they're not bad eyepieces).

    That's a good price on the Hyperion too. They normally retail at $130. I love 'em.

    Hello Craig,

    I have the ES 20mm 100 degree eyepiece and am very pleased with it. I bought it on June 28th of this year for $299.00 (I just looked it up for curiosity). "For the money", it's hard to beat. Is it perfect? No. Is it as good as Tele Vue? No. Is it worth the investment? Absolutely.

    I think Explore Scientific probably "fudged" a little when they noted the "MSRP". Sometimes, manufacturers inflate that price in a feeble attempt to make the consumer feel the eyepiece is worth more than it actually is. BUT, sometimes it can backfire, as it did in YOUR case. When it was "reduced" that much, it made you think there was something inherently wrong with the eyepiece. There isn't. Never in a million years would they EVER attempt to sell that eyepiece for $700+. They know better than that. One might as well get the Tele Vue, if the ES cost that much. They know that, too.

    It's my humble opinion that if you purchased the ES 20mm 100 degree eyepiece, you would be very satisfied . I can't offer an opinion on the Celestron ep, because I have no experience with it. But, I know Star Rider personally. If HE says the Celestron ep is a fine eyepiece, you can bank on it.

    Clear skies, buddy!

    This post & the comments are right on time for me too.
    I'm also looking into the Baader Hyperion line but I keep hearing how good the ES are for the price.
    The Luminos line is also in my list, I have to say right now the Baader Hyperion EP are my choice so far, going by the reviews & chatter I've seen while researching many EP over the last week.
