Celebrity Deathmatch: 22 Pan vs. 24 Pan
      #5841651 - 05/05/13 01:09 PM

Is one clearly superior to the other, objectively speaking?

I had both at the same time; and had a very difficult time choosing which one to keep. They are both very excellent eyepieces, excellent contrast! I finally decided on the 22Pan, as it just seemed to be more "submersive" while looking thru it; meaning it seemed that you were drawn into the view moreso than with the 24Pan. Both are winners!

I had them both.
22 pan has good edge correction and great eye relief.
24 pan has great edge correction and poor eye relief.

Take your pick!

I went with the 22 pan because I use Dioptrx and need the eye relief.

If I didn't need the Dioptrx, I would get the ES 24 mm 68 deg.

So far, it sounds like choice comes down to which performance characteristic is most important to the end user: eye relief, or edge correction.

In the common parlance, this characteristic is called "immersiveness", though I like your implication just fine.
With a coma corrector, I would have said the same thing about the 22mm. It's too bad it's been discontinued a long time. I guess the market preferred a smaller eyepiece and wasn't that enthusiastic about the 2" skirt (I loved it, sigh).

Yes - that is the way to do it with any eyepiece purchase choice. Figure which performance characteristic that is different between the options matters more to you and use that to make your decision.

Sounds to me like it's about ER... & possibly immersiveness.

Have had the 24mm... was a fine EP, optically, but had neither ER or "I" for my eyes.

Noticed in the forum that the Pan 24 is The Legend. Then not as much raves for the 22. Have the Pan 27, reckon it has great edge-correction and great eye relief too, a favorite that will keep.

Best,

It is interesting to read about the 22mm Panoptic. I have had one for a few years now, rarely use it. It just seems like the 20 mm Type 2 Nagler is an overall better performer, bigger, wider field of view, better corrected in a fast scope.

Of course the 22mm Pan is better if you drop it on your toe...

Jon; that may well be, however the OP asked only about the 22 vs 24 Pan.

Both of these eyepieces are excellent, and very difficult to choose a winner. Like most eyepiece choices it comes down to personal preference.

I have a pair of Pan 24 for binoviewing. Went with the 24 for maximum true field of view in a 1.25 inch format. I also use if for my very wide field of view finder when combined with the Stellervue 80mm finder. In my main scopes I stick with the 2 inch eyepieces. I don't wear glasses and don't mind glueing my eyeball up to the glass.

They're both great eyepieces and I think most users would be happy with either one of them. The major reason I switched to the 24mm Pan when they first came out around 10 years ago was because of their much smaller size and lighter weight advantage which made them much more suitable for use with a binoviewer than the 22mm Pans were. Another disadvantage of the early Pans (i.e., their 22mm & 35mm models) is that they required you get a special adapter from Tele Vue in order to with a Barlow. I never did use mine with a Barlow so me me that was a non-issue.

The 24mm Pan also has a 8% wider TFOV at 16% larger true field area which is another advantage they have over the 22s.

Even thought both are rated as having 15mm of eye relief I agree with others that the 22mm seems to have provide a little advantage in this area. I also agree that it seems to provide a little more immersive view. And the 22mm Pan also provides a little more magnification and a slightly darker sky background. The 22mm Pan has one other property I like and that is I think it is the best looking eyepiece that Tele Vue or any other manufacturer has ever produced. It is instantly recognizable classic Tele Vue but it is not so large in size as to appear ungainly.

If I had to choose between the two I'd probably pick the 22mm if I was buying it just for single eyepiece viewing and if its heavier weight was not going to be an issue with the scope I was using it with. However, if I had present or future binoview use in mind as well, then I'd pick the 24mm.

Other than the differences one would expect because of the small difference in fl, the only noticeable difference is the 24 has a bit better edge correction. I used the 22 Pans to binoview and they were great performers but they are large, could be a problem if one has a prodigious proboscis. The other binoviewing issue is that the 2" skirt can interfere with the locking mechanism in some binoviewers. I went to the 24's and am very happy with my decision, but I would be a happy camper with either.

The 2" skirt just threads off for those interested in 1-1/4" only operation. However, it does not change the weight very much (judging by feel alone).

A few years back I had the 24 Pan, 22 Pan, and 24 Brandon in house. Long story short, the 24 Pan was the one that got sold off. It was a great eyepiece but since all my scopes have 2" focusers the max true field aspect of the 24 never held any weight for me. Too easy just to pop in a 2" eyepiece and get even more field.

In addition to the 22 Pan immersiveness, I suppose a great deal of my opinion on this eyepiece is sentimental. The 22 Pan (along with the 9 mm T1 Nagler) was my first foray into the premium wide field world 20 some years ago. The 22 Pan was absolute magic in my f/9 Newtonian. It has never disappointed me in any other scope over the years.

As many have pointed out time moves on. A short while ago a nicely-priced 22 Nagler T4 came up on the 'Mart so I snagged it. I'm sure the A/B comparison will leave me very conflicted.

Just for reference, i understand this same skirt will *NOT* come off with the 12-T4 Nagler, even tho they appear similar.

Since i already have one of these, i wouldn't even THINK of trying the 22-Pan... but i'm sure it would be a fun comparo.

I did that comparo and sold the 22 Panoptic. That was a long time ago, too, like early '90s?
