I'm looking at adding a Nagler 22mm to my expanding ep collection. Has anyone had any experience with them? I need the long ER. Any other eps comparable?
Thanks.

Very comfortable, feels solid and much heavier than you might expect. I have not used it a lot, but like it a lot. It feels similar to the Pentax XW from the ease of use and comfort, just with larger AFOV.

The Nagler 22T4 is one of my favorite EPs. It has approximately the same TFOV as the 27 Panoptic, but 19% more magnification and smaller exit pupil. The ER is just perfect for me at 19mm.

The 22 T4 is almost always the first EP in the focuser no matter what scope I have out, mostly because of it's ER (glasses for astigmatism), wide AFOV, and wide TFOV. Comparables are the 17T4 and 12T4. In addition, the Celestron 31mm Axiom with it's outer casing removed for weight savings also has an 82° AFOV and ~20mm ER, good enough for glasses use.

Comparables with long ER at ~22mm all have less AFOV. The LVW is the obvious choice at 65° and the Olivion has 70°. There are some comparos in the current thread list about these 2. There are the 21 and 24mm Hyperions. The 21 has slightly better eye relief and is pretty well corrected at f/6 and slower. The 24mm is not well corrected for slow scopes but is OK at f/10 and higher. The 68° 24mm Meade 5K SWA has barely enough ER for glasses use but some with thicker glasses or more deeply set eyes may still not see the entire AFOV at once. It is very well corrected at the edges in fast scopes but not perfect, and no longer available new.

I have the 22 T4 and it is my workhorse eyepiece in my 9.25 Edge HD. I, too, need eye relief and this EP is very comfotable to use and the exit pupil of 2.2mm at 106x is perfect for a great number of objects. It was also a great choice in my 10" Dob for wider-field observing. Some have reported coma in Newts, but this was never noticable enough to me to be objectionable.

I liked the 22mm Nagler, but in time I came to think that they had a bit of field curvature.

I compared one to a 20mm T5 in my EdgeHD 8" and my 6" APO, and in the end, I sold the 22mm T4 and kept the 20T5.

Just my own opinion, but I think the 20mm T5 is a better eyepiece.

What sort of scope (s) are you planning to use it in. It is far from perfect in some situations and in others it is an exceptional performer.

It is certainly a winner on the comfort and eye relief factor. I use mine a lot in my F4.5 Newtonians but like the 17mm Nagler a paracorr is essential. With the paracorr it is an exceptional performer, without the paracorr it's pretty ordinary and its performance is not in keeping with its price when used in those scopes under those circumstances.

Cheers

I'll be using it in a 12" Orion dob. I do have the paracorr II. I'm thinking that this will fill the gap nicely between my Delos 12mm and ES 30mm

In my F4.55 Dob+P/C, i have a similar EP line-up to what you're describing- a 30mm Meade UWA, a 22T4, and a 13 Ethos; the 22T4 is so darn good, the 30mm Meade almost never sees light! :ubetcha:

In that scope with the paracorr II the 22mm Nagler will give excellent performance and it's where I would be heading. Keep in mind 22mm Nag + paracorr is a fairly heavy combo for a 12" dob with small altitude bearings but it is over 1/2lb lighter than the 30mm ES combo.

The Dob is an Orion with the "adjustable" bearing system to handle some extra weight. Just to be on the safe side I purchased some of the felt padded magnetic counterweights from ScopeStuff. They sure are sweet.

very true, unless you need the eye relief, which the 20t5 really does not have. the 20t5 is the best nagler i ever had but the 22t4 is the most pleasant to use

I had a 22T4 from the month it was introduced until a 21 Ethos replaced it a couple years ago. Even in the Paracorr, it still showed a little field curvature to my non-accommodating eye. But, by focusing slightly away from the center of the field, I was able to accommodate the entire field and see everything sharply.
It's hard to explain about that eyepiece. It has a high comfort factor and a great degree of immersiveness. Though I do agree the 20T5 seemed a bit sharper, it just didn't have that "je ne sais quoi" that makes an eyepiece really special in my f/5 (5.75 with Paracorr) scope (that might vary, of course, in other scopes). And the 22T4 was my favorite eyepiece in my f/10 SCT (near perfect exit pupil).

There are many comparably-comfortable 70 degree eyepieces, but in that general focal length range, there are only a few 80+ degree eyepieces that provide you the ER you need, and if you use a Paracorr, you'll like the 22mm.

You'll love it in you Paracorr equipped dob. Are you familiar with the Instadjust?

I've been reading up on the Instadjust. It sounds like it works pretty well. It will just take some time with these old eyes.

For many years the 22 Nagler was my most used wide angle eyepiece for a 12.5 inch, F5 telescope. I used it far more than a 31, and it was quite a bit lighter. When I bought a 13 Ethos, and was amazed by the presentation of a 100 AFOV eyepiece, I decided to buy a 21 Ethos. The 21 Ethos has now replaced both my 22 and 31 Naglers. However, if you are considering a 22 Nagler, I strongly endorse it as an outstanding eyepiece.

I've got a 22LVW, and I'm contemplating an upgrade to the 22T4. I tried out Starman 81's 22T4 and I found the eye relief rather cozy and it wasn't too straining to see the full 82-deg FOV. The 17T4 and the 12T4 were really, really finicky on eye placement. By contrast, the 22T4 wasn't that bad; comparable to a Delos.

And it was night-and-day with, or without, the Paracorr. At f/4.9, it's good-but-not-great in terms of edge sharpness. With a Paracorr, it's immaculate.

Clear Skies,
Phil

Phil,

Why would you want a 22mm Nag over the 22mm LVW? Is it really that much better? :question:

The 22T4 has a substantially wider field of view vs. the 22LVW. The latter is sharper than the former without a Paracorr, but since I recently acquired a Paracorr, I'm taking a second look at the 22T4.

The 22LVW also doesn't get along too well with a Paracorr. You need even more in-travel in 1.25"-mode than you do with a 14mm or 17.3mm Delos. The 22T4 can be set on the "5" setting of the older Type-1 Paracorr that I have and it works great.

I tried Syed's 22T4 out and it really had that certain, "oomph"--a wide field of view, a 3.9mm exit pupil that's great for wide objects, yet maintains more sky contrast than a lower-power ocular.

Clear Skies,
Phil

My primary scanning EP for most of my scopes is a 26T5, but I still use the 22T4 as a backup (for a second scope when those rare occasions arise). In general, I find myself using the 22T4 more on my refractors than on the big dobs.

It is a solid eyepiece and a reliable performer. My lesser use has more to do with its focal length in my lineup rather than its quality. Still, it fills a need.

I'm considering upgrading from my 27mm Panoptic to the 22 Nagler. My wife has the 22 and it is very nice.

It fits the gap perfectly. I've got the almost identical set-up (12" Dob, T1 Paracorr). You still get a full 1* field even with Paracorr. I've had a newer version 22T4 for a few years now and love it. The instajust is tight enough there is no slipping. Very solid well crafted eyepiece.

Just be careful screwing filters on the bottom. The field lens hangs pretty low in a convex manner.

I agree with many of the positive points mentioned here about the 22T4 Nagler. The immersiveness coupled with the higher magnification and smaller exit pupil make it one of my most used eyepieces and keep other longer f/l eyepieces in the eyepiece case. It is quite comfortable even with glasses on and it is not too large, though it is dense.

I use with the PC2 in the STS 11 and w/o coma correction in the 8" dob--until now. I snagged a Baader MPCC and plan to use it to perfect the views while not taking away from the TFOV.

Phil,

Why would you want a 22mm Nag over the 22mm LVW? Is it really that much better? :question:


If you own a dob 12", or larger and a paracorr T1 or T2, the short answer is, "yes it is". It gives a larger TFOV and a much more immersive view than the 22mm LVW.

In 8" and 10"/f5 type scopes I prefer the 27mm TV Panoptic without paracorr rather than adding the extra weight of the 22mm Nagler and Paracorr. If you don't own a paracorr and your scope might experience balance issues the 27mm Panoptic or the 22mm Vixen LVW are better options. I have left the 24mm Panoptic out of the discussion as it has shorter eye relief and IMO is less versatile and does not give as immersive a view as the 27mm Panoptic.

Cheers
