Both ARE coming back, and they will be less expensive than the $579 they were before.

I do not have a time frame, so don't ask.

But, "it is in progress" per Ricoh.

Wow, you serious? 

 

Great news!

 

Never thought I'd see this happening. Tried the 40 already, may go for the 30 or 40 again for Nebulae.

Guy at Woodland Hills Telescope and camera said they're coming back end of the year. Was in the store yesterday, he just volunteered the info. Personally I am sold on my 40mm Paragon.

That was the date I heard, too, but I wouldn't guess it would be available until after the new year because of production schedules.

When a date becomes firm, it'll be known by all.

No--I would buy instead the 31 Nagler or the 21 Ethos.

Are the current XW30 and XW40 parfocal with the rest of the line up?

No interest in the XWs, however I wish they would bring back the 5mm XO and maybe a new 3.1 XO. Other than that maybe Pentax could make a 2.5" 60mm XW? That I could use....

I first read that as 2.5mm 60 deg XW, something I've been wishing for.

I would buy the 30 and 40 XW to try them out, to see what all the fuss is about.  I'd compare them to the eyepieces I already have.  Then I'd decide whether to resell or keep them.

 

I can see possibly selling the 41 Pan after acquiring a 40 XW.  If the 40 XW is lighter than the 41 Pan, but has equal or better performance, the 41 Pan is gone.

 

I don't see getting rid of the 31 T5 if I get a 30 XW.  82 degrees vs 70 degrees.  

 

So probably I'd just get the 40 XW and not the 30.

The 20mm is reported to have mild field curvature. Which would explain what you saw. The other eyepieces in the series other than the 14 are something special, but maybe not compared to Ethos, Delite and a terminagler.

I had the XW 3.5, 5, 7, 10 and 20.  In my 10" f/4.8 Dob, without a Paracorr, the only one that I noticed FC in was the 20mm.  The FC in the 20 was obvious and pretty bad.  But with the Paracorr, if I focused about half-way out from the center, the stars looked sharp from edge to edge through the 20mm XW. 

 

This was about five years ago.  I think my ability to accommodate for focus has gotten even worse since then.  So if I buy the 30 and 40 XW and they have obvious FC to my eyes, they'll probably be going to new homes.

Perhaps.  I already have three 40-ish mm eye pieces: Optiluxe, Pentax XL and Gary Russell.  Suddarth Optical just fixed my Optiluxe, so it's back to being my favorite.  The XL would be, but it needs fixing, too, I think (I think the lenses need separating, cleaning and recementing).  The Gary Russell is bright, really bright, but the eye relief is longer than I need.  I need to bring a toilet paper roll out and cut it to length as a guide for eye placement.

 

I have resisted the 41mm Panoptic due to cost and weight.  Besides, in my slow scopes (f/10 and slower) there was no advantage to it over the Optiluxe (which is terrible in fast scopes).  

 

Still, as enthusiastic a following as the XWs had (have in shorter focal lengths), I might try one...

Old vs new should make for an interesting read here....New ones better due to coatings?  Old one have better polish? New ones made with better tech? Loss of the employees who did hand figuring of lenses (new ones will have a learning curve?  Do the new ones smell right?

Hand figuring of lenses? I wouldn’t stress about that one. But yeah it would be interesting to see what the differences are. Maybe the key advantage the 40XW always had over the 41 Pan, or 31T5 or 21 Ethos for that matter, is light weight. And 20mm ER. Those aren’t important to everyone but they are important to some. The 41 Pan has plenty of ER at least.

I too bought to see what all the fuss was about. The XWs 30 and 40 are excellent eyepieces, but I find the 41Pan and 31N to present better images, for my eyes anyway. Better corrected on the outsides of the field. The XWs though are lighter and have a much better form factor, and I love the Pentax eyecups. With their eye relief and extendable eyecups, they are perfect for using for outreach, and that is how I use them. For my own observing, it's the Pan and the Nagler.  YMMV.

The 41 Pan has plenty of ER at least.

Most eyepieces around 40mm have ample eye relief.  I wouldn't be concerned about that.  The 41 Pan has 27mm eye relief.  Does anyone need more eye relief than that?   In fact, I can't think of any 40mm eyepiece that is lacking in eye relief.

 

But there is a big weight difference.  The 40 XW is 24.7 oz.  The 41 Pan is 33.6 oz.  So the 41 Pan is over half-a-pound heavier.  Probably also quite a bit larger in size as well.

 

On small scopes on light-weight grab-n-go mounts, I'd be reaching for the 40 XW rather than the 41 Pan.

I had a Pan 41. Wearing glasses the top cone needed removing to get max eye relief, but that left a metal volcano top.

 

I hope the XW 40 is better than that for getting its max eye reluif.. My Meade SWA 40mm is, and much lighter Vixen LVW 42mm as well. Ditto Pan 35. So a XW 40 might be as nice as a XW 10mm, at least.

The 30 and 40 Pentaxes are just as comfortable to use as their smaller brothers.  In fact, the entire Pentax XW line is so comfortable and easy to use -- they work very well for public outreach.  I used mine for public outreach for a few years and I never heard any complaints or problems from anyone trying to view through my scopes.  I dialed out the eye guards about four turns and let the public enjoy the views.  There was never any hesitation or waffling.

 

"Just look right through there, ma'am."

 

... and voila! 

 

"Wow!  Is that really Saturn?" 

 

It was a lot of fun. cool.gif

 

When eyepieces are this easy to use, they disappear like the rest of your gear should and allow you to simply sit back, relax, and enjoy the views.

 

Cheers,

 

Ron

A XW 40mm will be my final eyepiece. It would replace the other 40s I own, selling those to help buy it.

I thought long and hard about going with the Pentax XW line for my lifetime premium wide-field eyepiece set. But in the end, I decided to drink the Televue kool aid. This decision was partly due to the lack of availability of eyepieces in that line with focal lengths greater than 20mm. In any case, I'm not going to change my religion now. I'm all in on Nagler/Delos*

 

 

 

 

 

*Unless I hit the lottery, in which case I may end up owning every eyepiece ever made by anyone.

[Looking through Pan 41]  I can see the entire field to the field stop while keeping my eyeglasses on.  I keep the eye cup on, but fold it down.  I push my eyeglasses firmly onto my face.  I lightly rest my eyeglasses on or directly above the rubber eye cup.  No problem.  YMMV

 

However, I must admit that the XW's I owned were some of the most comfortable eyepieces to look through.  The exit pupil was easy to find and maintain.  By comparison, the Radians were some of the worst eyepieces I have ever owned in this regard.  In general, in my opinion based on my experience, Tele Vue eyepieces are not as comfortable to view through as the XW's.

I could, using your approach, just see the whole FOV on the 41 Pan, but compared to the ease of my 35, expecting the 41 to be easier still, was disappointing.   

 

With any new ES92, the big XWs are what I hope 2020 will bring to me.

 

Do the 30 & 40 Barlow well? -
