​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.

Definitely agree!

 

I thought they were a bit strange at first, but then I realized that the hard-shell "dome" on the top of the eyepiece was a perfect fit for my face.  The Pentax eyepieces just settle in and it's easy to position your eye to see everything easily.

 

When I discovered the TV Ethos and moved to those for my personal observing, the Pentax remained as my eyepieces of choice for public outreach.  They are so easy and comfortable to use; everyone was able to enjoy the views.

 

I finally sold them, but had to scramble around after my cataract surgery to buy them back again after I discovered that I needed eyepieces with more eye relief.  They will stay here from now on.

 

Again, congrats on buying the whole set!

 

Ron

In old archived scrolls the XW Buddha reveals how to fit a Dioptrx lens to XW 30 & 40mm eyepieces https://astromart.co...x-xw40-and-xw30

I’ll need to take a look at that.  I do have astigmatism.  Not severe, but annoying at low power.

It was very successful, thanks!  There is a thread somewhere here on CN where those of us who had the surgery compared our results.

 

My 2.0 eyes are great.  I still have 20-20 vision and when we took the bandage off the first one, the world was much brighter and colors were true.  White was "white" again, etc.  cool.gif 

 

Cheers,

I'm curious about how most non eyeglass wearers use the twist up eye cup.  Do you find it useful to twist it up some or do you keep it screwed down?  I received a 40mm today and will hopefully be able to try it out tomorrow in a 10" SCT.    It really doesn't seem to have much range before it just totally unscrews, so doesn't seem like it would make all that much difference.  Also, it's gets a little loose towards the top end of the range which I don't really like.  I'm hoping that I can just be satisfied with using it screwed all the way down.  I love the looks of the big glass though.

Doh! Just figured it out, I was just unscrewing the ring at the top.  Basically the whole top half of the EP twists around giving you a pretty large adjustment range.  Much nicer! Now I'm impressed.

Under that top cap are threads for mounting a camera.

Tim,

 

To answer your first question, I do not wear glasses, but I like to twist the eye cup up about four (out of the five) turns.  This puts it at a very comfortable place for me.  YMMV! cool.gif 

 

Congrats on the 40.  It has always been a favorite for my long focus SCTs and Maks.

 

Cheers,

 

Ron
