I'd sell those ESs and buy a 10mm XW in a heartbeat. 

Well, maybe you have a good idea. I would then have this range, 13mm T6, XL 10 mm and then the ES 6.7mm. Then if I where to observe planets, I'll just use my BHZ 8-24mm zoom?

 

How does that sound?

The Pentax XW 14 has received more than its fair share of criticism here on CN over the years and if I had seen the complaints before I tried it, I might never have known how good it is.  But I bought mine before I saw the posts and I have never had any problems with it the past 12 years.  It works fine for me in all of my scopes - refractors, SCTs, and Maks.

 

 So true! waytogo.gif

These XWs are a real treat. They are very forgiving with eye position and are as sharp as any Tele Vue eyepiece I have used.

Like many Field Curvature issues, it depends on your eyes.  Some can adjust better than others and you won't know until you try it for yourself.

In fact my 14 XW is my workhorse ep on every clearnight. I don't see those "issues" either even at f 5.8.

 

My 10.5 XL is also a great ep. Using it for a little more magnification...

 

And my 40XL is my finderscope and MW scanner for almost 15 years...imo maybe the best Pentax out there...

Hard to compare as two different designs, one is 70 the other 82 afov. Also depends on scope, eyes etc. I agree of the t4s the 12mm is the weak one. I find the 22 much better, and the 17 the sharpest across the fov in all my scopes by a thin margin most noticable in my 8". In my 18" with a Paracorr they were more equal.

I envy you your two XL eyepieces.

I’m glad to hear you guys have had success with the XW 14. I may pick one up after all as it hits the “magic” 2mm exit pupil in my scope. The 22T4 is super sharp but also shows much of the awful sky glow we get this time of year.

 

It may be time to trade in my 35 Pan for something more useful. It’s a great EP but I just don’t use it much...

Go up in AFoV and get the 12 and 17 ES92s! 

 

For 80° I have the less heavy Orion LHDs. For me, they have better eye comfort than T4s, and sharp bright views.  

Please tell me how you like those Orion LHD’s compared to the Pentax XW’s? I can’t remember who makes those for Orion but they look nice. I’ve wanted to try them.

I have the same situation with 30+ mm eyepieces. I have a 34/68 that I rarely use at all. I recently went to a dark site and never used it, preferring the N22T4 instead.

The Orion LHDs are made by Long Perng in Taiwan. Being 80°, they have 10° more AFOV than XWs,  and like XWs, all have 20mm eye relief. No field curvature or n

blackouts.

 

The 14 & 20 are 2" fit. Wearing glasses I can just see the whole FOV, and like the Pentaxs eye comfort and exit pupil are easy. With a 10 XW & 30 APM UFF, the two LHDs make a nice set.     

 

It's a shame that the LHD Lanthanum range is either too unknown or dismissed on CN. They are prime quality, well made with flat field and easy use compared to Naglers and ES82s.  More retailers needed to sell them perhaps.

But not 20mm useable eye relief in the case of the 20mm ?:

The 14mm is a little easier strangely, or not, maybe. My 14mm Morpheus is comfier.

 

Both LHDs are easier than T4 Naglers, which is why I chose them at the time.

 

A millimeter is such a tiny unit, and 10mm = 1cm. It's very hard to know how accurate from one use to the next! Exit pupil ease of access is equally important, and the Orions are good there,

Ironically I probably had most of my best views tonight with the 35 Pan, considering it was mostly fainter stuff (globs and planetary nebulae) and the skyglow wasn’t too bad. Still, I received an offer on it and the funds are best used elsewhere, I think. Maybe the future will hold a 41 Panoptic or 31 Nagler...or there’s always the ES 30/82. I do like the 82 FOV for wide field stuff.

 

The real winner tonight was the XW 7, though. Jupiter was in a good location so I popped that sucker in and my, was it a nice view! Even at this modestly low power (102x), cloud belts were clearly visible with excellent coloring. I only wish I had a way to crank up the magnification more, but not yet...I need a Barlow, I think!

With my 102 my favorite low power EP is either a 27 or 24 Pan, both light weight and sharp to the edge!

I find the pincushion to be a bit disorienting at times, but the Pans are fantastic.

I can live with my 22T4 for the time being.

I think the 22T4 will be very good in your AT102.  It's a fairly short focal length and you should get a tick over 2.5 degrees with the Nagler.  To me, a 35 Pan would be like using binoculars with only one eye.

 

I tend to stick with about 40x for my low power views and only use 1.25" eyepieces in my short Tak 4-incher.  The Pentax XW 20 is my favorite in this scope for low power.

 

Cheers,

 

Ron

I have the 20mm XW and 22mm T4, both are very comfortable and very sharp.  I'm a big fan of the XWs, but I consider the 22mm T4 among the best eyepiece I've owned.  It is especially good if you wear glasses, just as good as the XWs in eye relief.

I found the XW's to be excellent. I sold mine for Delos eyepieces because I liked the focal spread better. I loved my 22mm T4. It is light weight and gave excellent performance. I only sold it because the 21 Ethos blew my socks off, and therefore did not need the 22 Nagler.

My bank account is happy that the Ethos doesnt have enough eye relief for me.  But I don't need glasses under a 1.6mm exit pupil, so a shorter focal length Ethos may dent the bank account at some point.  ;)

As is mine. However, the ES 92s solve that problem. I’ve used the 17mm and it seems to be every bit as good as the 17mm Nagler. I’ve never used an Ethos, nor do I think I should open that can of worms...

 

I would like to try the 12mm at some point. I don’t use glasses, but I like find long eye relief more comfortable and it lessens the amount of eyelash goo that gets on the top lens.

Its not eyelash goo, its photon slime....it just builds up on your eyelashes.  Pentax XWs are designed to prevent photon slime.
