    Default Televue 15mm or Explore Scientific 14mm (82 afov)



    Hi everyone, thanks for all the help so far,

    I currently have a 15mm Televue Plossl on order, I noticed for $25 more I could get the 14mm Explore Scientific with (82AFOV). Any opinions on these eyepieces would be much appreciated.

    Well, I have both of these two EP's in consideration:


    Explore Scientific 14mm (Series I); TeleVue 15mm plossl

    As you've mentioned, the ES14 has an 82° compared to the plossl's 50° AFOV, and the 32° difference manifests itself when you peer through both swapping each one after the other in the scope's diagonal. TV is the gold standard of plossls and very sharp on-axis, many swear by them and will not accept anything less, to be able to catch those details that are not apparent if other EP's are used. The ES on the other hand is a new-kid-on-the-block which has been making waves in the EP community by introducing a viable 100° EP in the market (I also have the ES 14mm 100°, but that's another story) to go head-to-head with TeleVue's 13mm Ethos 100°. The ES14 82° is now in its 2nd incarnation, the N2 series, which unlike the one in the above pic is waterproof and nitrogen-purged, just like the 100° which helps prevent fogging and makes the EP impervious to unexpected events like rain/heavy dew. I bought my non-waterproof ES14mm last year for $99, they're not perfect at the edge but considering that the view is so expansive at 82°, the sharp area is definitely over the 50° true field of the TV15mm. If you're interested in the wide spacewalk views, get the ES 14mm N2, they are on sale as you might have known for only $99 which is a very good value, probably the "best buy" in EP's today.

    Best,

    Hernando

    Thanks alot Hernando, very helpful.

    I decided to go with the 14mm ES, Just what I am looking for and not much more than the TV. I certainly would like a widefield ep in my collection, probably 2. The extra eye relief is a factor aswell as my wife wears glasses. Like you said also, great buy. (1/2 - 1/3) off depending on the site.

    Im probably going to pick up the 32mm TV plossl, while the sale lasts, and a GSO 2" 40mm eyepiece to round out my collection for a while. Still somewhat undecided on those 2 though.

    Thanks again for your help

    You're welcome, always glad to be of help. Yes, a lot of people are taking advantage of the 20% off on TeleVue EP's, the price war is really to our advantage, as EP buyers; if I didn't already have the 32mm plossl, I would have bought one myself during the sale these days. I also have the GSO 42mm, it's not the best (have around a dozen long focal length EP's in my collection), gets to be soft at the edges in fast scopes, but for occasional use or as a finder, they will be fine. But if you're into low-magnification viewing and spend a lot of time there, I would look elsewhere than the GSO 42mm.

    With regards to eye relief (ER), be aware that the ES 14mm is considered by some to be kinda tight; for me it's not a problem, it could use some more mm's but is fine as it is; but it is definitely not for one who wears eyeglasses while observing (still can be used with glasses on, but with reduced field of view, maybe from 82° down to around 60° to 70° remaining).

    Best,

    Hernando
