    Default Shootout Of The 12mm EPs



    6/14-15/2016

    Last night I arrived home from work to some openings in our cloud cover and a bright moon. I decided to do a lunar shootout between my 12mm Delos and 12mm X-Cel LX. In my 4.5" Newt a 12mm EP gives me a very usable 75x magnification, perfect for framing the moon nicely and enough power to start picking out some finer details.

    The Delos was up first, I focused on the moon and immediately noticed how sharp the field was right out to the edges. Background sky was nice and black, the subtle lower contrast features on the lunar surface were beautifully rendered. I swapped for the X-Cel, and while there was a difference it wasn't a huge difference. The Delos wins for contrast, although the X-Cel for only $64 performs on a level quite close to the much more expensive EP. Focus was sharp in both EPs, with a slight edge to the Delos and the background sky was almost too close to call, slightest edge to the Delos again.

    I did try for some views of Saturn and Mars with my 6.7mm EP, but the seeing was pretty much complete crap so I packed up and headed in at this point.

    Bottom line, the Delos is the better EP, but the X-Cel is certainly no slouch and at $64 it is probably the best option in that price range. Obviously there's quite a difference in FOV between the 60* for the X-Cel and the 72* for the Delos, but both are extremely comfortable to view through with generous eye relief. The most noticeable optical difference was in the lower contrast lunar features, but even here the X-Cel performs more than well enough at its price range. If you don't have the money for the ES or TeleVue options, the X-Cel EPs are an excellent low budget choice, I don't think you'll get better performance out of any other EP under $90. Thanks for reading, clear skies!

    What you noticed is what I found when I compared the ES 82 11mm to the AT Paradigm 12mm. Tossing the obvious AFOV difference aside (82 vs 60), the Paradigm accorded itself well against the ES. Of course the ES beat it in all categories as one would expect, but for an eyepiece that was bought used for less than half the price of the new ES, it was, as you said, "no slouch". If I had to keep myself to a tighter budget, I certainly would have no qualms about using the AT Paradigm Dual EDs or the Agena Starguider Dual EDs (same thing with a different name). There certainly are excellent alternatives to standard plossls without breaking the wallet.

    Thanks much; it's reports like yours that make it easier for people like me to make an informed decision. Funny, for my next eyepiece I had it narrowed down to the X-cel or the Delos. We'll see how the budget goes.... Glad to know they're both good in your opinion for what they do in their price range; in my books your opinion (and others here, of course) is more than good enough for me.

    Thanks again and all the best for continued clear skies,

    Wings, a six-element fully multi-coated lens EPs for $64 - wow!

    I have a 12.5mm Sirius Plossl in my EP box, but haven't used it in a few years.

    I'll need to take stock of my EP collection to see which ones need upgrading...

    Best deal I've found on the X-Cels are on Amazon for around $64 apiece, but you'll have to nose around on there a bit. Next best was Agena where they are listed at $68. Most reviews I've seen rate the 12mm and 9mm as the two best in that line. The eye relief is much more comfortable than standard Plossls of the same focal lengths.
