I don't believe the OP mentioned any weight or price restriction.

 

And, I'm asking Don as I believe he doesn't wear glasses to observe, thus eye-relief is not an issue.

I use Delites in my f/7 triplet refractor.  That scope has a 714mm focal length, so the Delites have an adequately-wide field for manual tracking.

At the lowest powers, I use a 24mm and 30mm APM UFF, for glasses, in that scope.

 

In my dob, I use Ethos eyepieces below 11.5mm, the limit of my astigmatism.  I wear glasses at longer focal lengths, so use eyepieces with longer eye reliefs.

I take my glasses off with eyepieces of 11mm and shorter.  I have a fine 11mm and a fine 22mm fr glasses use, but I haven't settled on an eyepiece in between.

I'm trying out 4 different eyepieces there, to decide on the one I find most entrancing when using glasses.

 

I have never worn glasses to observe, but over the last two years, my astigmatism has worsened, so I need glasses with exit pupils of 2mm or larger.

No weight or price restrictions [no restrictions at all really]. Just wanted to see what each of you like to use for Lunar observing.

So if I read this right, when using your Dob, you have to use your glasses for the 13, 17 and 21mm Ethos?  Are you losing the full 100º AFOV?

I'm replacing the 13-21 Ethos with 3 longer eye relief eyepieces because I can't see keeping them with the hope that some day I'll have less astigmatism. I have no cataracts forming, so lens replacements are years away.
I prefer glasses to a DioptRx for ultrawide eyepieces so I can look through the eyepiece at a very oblique angle without distortion.

I have 13, 9 and 7 T6 Naglers.  They are outstanding, however my 5mm Pentax XW is the creme de la creme for lunar observing, in my humble opinion, especially for those wanting long eye relief.  I find the contrast jaw dropping, and finer details seem to pop out at ya, especially when the atmosphere is cooperating and the scope is at ambient temperature. 

 

I have never compared the 5mm XW with another 5mm so I could not write a comparison.

mine used to be the 12mm Dual ED when I viewed cyclops style, but now that I binoview, my favorite is the 25mm HD Orthoscopic eyepiece pair.  With a 2x OCA, the HD Or gives 60x and a very pleasing wide view of most of the moon at once.  It even looks like etched metal with how defined and sharp it is.  The 12mm Dual ED gave a view of the entire globe if I remember correctly(sadly sold it) and always impressed whomever looked at the moon with it.  Even though my glasses almost touch the eyepiece, I am considering a pair of them for binoviewing at higher magnification.

 

Both the 25 HD Or and the 12 Dual ED are winners.

It depends on the scope.  For either of mine, 100 mm f/9 and 60 mm f/6, it's a DeLite.  5 mm for the f/9 and 4 mm for the f/6.  Any smaller exit pupil and my floaters get in the way too much.  One exception is I used my 22 mm Nagler in the f/9 for the total lunar eclipse a few years ago.  That was more of a whole Moon event that called for the wide FOV.

 

I really like the DeLites.  Even though some don't care for the 62° AFOV, you can get near perfection with just enough eye relief for eyeglasses, without breaking the bank.

Do the DeLites introduce any false color [yellow-green] on the lunar limb?

Not sure if the scope matters, but my 11 and 3 DeLites do not. There is not a shred of false color anywhere in the view in my newt.

No.  A couple people here on CN say they see a slightly bluish tint to the outer field in the 18.2 and 15, but those are the only comments I've ever heard to say that.

I have not seen that myself.  But Delites are excellent moon viewing eyepieces.

DeLites are fantastic in all focal lengths. IMO, they are perhaps the best corrected eyepieces TV has produced to date. I was not convinced with all the high praise they received when released, but that held with time. I finally tried them last year and glad I did.

Ok kool! I used to have the 4mm DeLite but only used it for observing Jupiter, Saturn, and certain Lunar craters & features. The magnification was a bit too high that i didn't notice the limb of the Moon [my experience].

I mainly use my apm 5mm(its 4,77mm if im not mistaken) 110fov for my lunar observing and its amazing, extremely close to tv ethos. If you are using glasses you need to look as close as possible to get 110fov, if that's a problem for you I suggest something like tv delos with better eye relief, but less fov.

I have been super happy with my Pentax XW’s 10, 7, and 5 mm ep’s. Seeing is generally good or very good where I live in Florida and the 5mm spends the most type in the focuser producing 317X mag easy. I think my next purchase will be the 3.5mm XW.

One of my favorite things to do when observing the Moon is to get the limb of the Moon at the edge of the eyepiece and let it drift across my field of view ..Makes me feel like I am in it’s orbit :) Having tons of fun working on the AL Lunar 1 program. Little more than half complete.

10mm 100AFOV Ethos in my 17.5" f4.1 dob fills the view like a 6 foot (2m) diamter moon 3 ft (1m) in front of you, with a little margin (only super perhelion moon overfill the view).  Very clear.

I'm a firm believer in keeping the exit pupil bigger than about 0.5 - 0.6 mm so I select the optical elements appropriately. On my TOA150 this translates to 240-300x.

 

I binoview almost exclusively & have a BARCON / ADC plus 1.25 & 1.7x GPC's. When combined with my 5 or 7.5 LE or 10 or 16 ZAO's, the moon almost always offers something interesting. A favourite ... well that would have to be one of them. wink.gif

If seeing is Avg, I usually stay with the BHZ MkIV for the session so I can quickly dial-in the correct mag based on target and varying seeing conditions...

 

However, if seeing is VG ( or >), I gravitate to my 7,5,4 and 3DL’s.  If seeing is truly Excellent, the Vixen 3.4 & 2.4 HR’s are used to tease out the last bit of detail.

 

Clear, steady nights.

Oddly enough, a pair of 25 CZJ Huygens in a slow scope. They really make the moon appear as a real, solid object. Other pairs include 18 HD orthos, 21 RKEs. For singles, 10 zao2, 10 Pentax XW,

While I've always enjoyed binoviewing the moon with ZAO's they don't give me the pure amazement that my Ethos do on the moon. Spectacular with that well corrected wide fov. I guess I could binoview Ethos but until I can get my cataract surgery on my left eye binoviewing is taking a back seat, kind of a waste.

 For me it's my 13 Ethos, 9 WO 101 and 5 WO 110.  After that my 11, 9 and 7 T6s, 14 Es  82  and 16 WO 82. I prefer a bigger FOV for Lunar and don't need long ER.   David

My favorite right now is the TeleVue Apollo 11. The magnification is perfect in my SCT with usual seeing. There is nothing I can see better with shorter FL eyepieces. Sharp till the very edge.

However, I'm considering adding a Delite 11 mm. With the Apollo there is sometimes too much fully featured real estate and light. The Delite 11 seems to mark all boxes: <70 °, very sharp, magnification, long eye relief for comfort and cleanliness (glasses not needed), small size for grab and go, and "affordable" for such niche application. I could consider bino, but I'm not into making that investment right now. (And certainly not with the Apollo...)

Opinions welcomed.

Opinions welcomed.

I have both of those eyepieces, and they are very different.

In one scope (focal length 1826mm), I need the real estate of the 11 Apollo or the 10 Ethos.

In my other scope (focal length 714mm), the Delite has plenty of true field.

In an SCT, 11mm could be a planetary eyepiece, but not in either of my scopes.

Definately my Brandon 32mm and especially a pair of 16mm Brandon in my BV. For some reason, the Brandon just works wonders on the moon!

12mm Brandon.  Of all the Pentax SMC, various orthos I've used, the Brandon had better contrast and showed more detail on the moon and planets for me.  Of course, you have to live with the small FOV, which doesn't matter on planets, but may for the moon.

I don't know what it is, but the Brandon's give me the best possible view of Luna I have ever had! That's why I call them My Moon eyepieces. A set of 16's in my BV is a killer on Luna.
