I have to use Delites or Nikon SWs, as fattest for bino viewing. Sadly XWs & Baader Morpheus are too porky.  

Some say they can use the 20's in binoviewers.  I could not make them work.

A comparison of the 10.5 XL & 10 XW here https://docplayer.ne...ts-com-com.html

 

I would love to find the rare XL 28mm 55° which was replaced by XW 30mm 70°. The little Tak 28mm 60° Erfle comes closest.

Enjoy! I love the smell of XWs in the morning.

BTW anybody knows why XWs smell that way?

Its the boxes & their padding packaging. My new 30 & 40 had the strong smell. I left them in the open & the smell went, same for their bolt cases.

So I did get up early this morning and used the 7mm and 14mm on my ETX-125.  Once again the images were sharp and very bright.  Jupiter was filled with detail, Saturn was great as well.  Even Mars showed some detail.

 

These are wonderful eyepieces.

Can someone make a Pentax with a 90-110º Field of view, asking for a friend, lol.

 

Imagine that eyepiece though. I'd be first in line.

A revival of Pentax SMC XO and O would be enough,

ES92s have the eye relief and immersive views Pentaxes give.

A huge benefit for me is that I can observe through them with or without wearing glasses. The Pentax XW, as well as the Vixen LVW, just hit the goldilocks comfort zone: FOV, build, quality, and a pleasure to use.

Best,

My first XW was the 10mm. I bought it as there was no LVW version, & it was recommended on SGL forum, where I was at the time. I also wanted to stay Japanese.

 

Now I have a Nikon 10mm NAV SW and Baader Morpheus 9mm. Both those are find for glasses, though the Nikon is only just, its the one that would go if need be, though its views are bright & contrasty, and weight lighter. All 3 have their own charms, the XW is most luxurious to use.

 

For 7mm, my Pentax XL & Morpheus 6.5mm are both great, the Morpheus has 11° more AFOV.

 

5mm FL its 5.2mm XL v 5mm LVW, a closer match, both 65° AFOV. I prefer both to my 4.5mm Morpheus in general, As the Japanese pair have steadier exit pupil behaviour.

My first XWs have been the 10mm and 7mm for the galaxies which have not been included in the Messier catalogue.

Then I have purchased a preowned 3.5mm for the planetary nebulae.

And when there have been rumors about discontinuation of the XWs because of Ricoh, I have purchased the 5mm in the U.K., where it has been way cheaper than in Germany.

 

The longer focus lengths with wide field are covered by the spotting eyepieces from Leica, Swarovski and Zeiss.

The Docter and Rodenstock are just the singularities in my arsenal.

 

Best,

JG

Despite the rumours I was greatly relieved to get the XW-R 30 & 40 last December. Originally my plan was just a 40, but in case Pentax's owner stops them again, I bought a 30 too. My 7 & 14mm XLs followed, a 28mm XL is the new quest.

I did the same thing for my 30 and 40.  They’re coming tomorrow from B&H.

Congrats on the set!   I just got my first Pentax XW in 3.5mm in from Don @ EyepiecesEtc.  Night just fell and I threw it into my Televue 101 f/5.4 to peek at the DoubleDouble. Even though it was just 30 degrees above the horizon and the seeing was so-so around maybe 1.4 arcseconds, the split was clear as day and stars were super sharp across the field, edge to edge.  I could even resolve stars in M13, which has always been a challenge with my 4".  I usually don't bother with globs with this size aperture due to the severe light pollution of my viewing environment...Wow.  XW is a winner.

The 30 is my favorite low power.  In my 15” Obsession, it just frames M31, 32, and 110 very well, and the whole dipper asterism within M45.  Incredible views.

 

The 20 and 14 show field curvature but the Paracorr cleans that up very well.

 

Congrats on getting the full set!  I have them all and use every one of them.

I heard that those eyepieces are outstanding in slower telescopes as refractors and cats but not so much in faster Newtonians, is that truth to it?

The 30R and 40R just showed up.  I get the “Buddha” reference.  Being 2 inch eyepieces, they are significantly larger “around the middle”.  I think they would be at home in the 200 inch Hale telescope, where at the prime focus of the mirror f/3.3, the 40mm would yield only 419X.

The only two that don’t do real well in fast Newts are the 20 and 14 when used without a Paracorr due to field curvature.  A Paracorr cleans them up nicely.

So the last one (the 10mm) arrived tonight.  My first impressions:

  1. All of them exude an air of being well made.  There are no nicks, smears, blemishes, nothing.
  2. The machining is very precise.
  3. The coatings on both the field lens and eye lens are extremely dark.  Reflections from a well-lit, sunny window are very dim.
  4. The eye lenses are quite large and inviting.
  5. Looking through them at a brightly lit window, such that the entire field is illuminated, shows a sharp field stop on all of them, and no dirt or anything on the interior lenses.  And before you laugh, I bought a couple premium eyepieces about 5 years ago for around $329 each that had dirt, etc. inside.  I sent it back, and they cleaned the exterior of the eye lens and the field lens, even though I asked them to take it apart and clean the interior.  Of course when it came back it was still filthy inside.  Finally I complained enough in the forums here, that someone From the company told me to send it to them again, which I did, and they finally took it apart and cleaned the inside.
  6. The eye lens cap and field lens cap fits perfectly.
  7. Each one comes in a large, screw eyepiece bolt.
  8. The screw up eye cup not only excludes extraneous light, but makes it easy to position your eye so that there are no “black-outs”.

​I have also come to the conclusion that someone at Pentax is a heck of an eyepiece designer.  I don’t know the timeline and all, but they seem to crank out some excellent eyepieces.  The 0.965 SMC Orthos, the XOs, the XWs, etc.

 

Anyway, I’m looking forward to actually using them and will update my comments then.

I've got 4, from the 3.5 to the 10 and they are my most prized eyepieces. I concur with everything you just stated, Sandy.
