After a long wait, I finally took the plunge on a gently used 41mm Televue Panoptic.  When it arrived in the mail, I was surprised as to the size of this eyepiece!  This thing should have it's own zip code!  The large box gives an impression of the size of the 41.

 

I used the 41 for the first time last night on my CPC Edge 800 HD.  Wow.  The large field of view, easy eye relief, jet black sky and pinpoint stars make this legendary eyepiece true to its reputation.  M42 and the Pleiades were especially fun to view.  I have the 27 and 35mm Panoptics, too.  While all these eyepieces share similar Panoptic traits, the 41 seems to be in a different class from the others.  Looking at stuff through this eyepiece is just fun.  I'm amazed and will enjoy using this eyepiece for many nights to come.  The CPC had no trouble with the added weight.

 

If you are considering this eyepiece for your collection, I highly recommend it!  waytogo.gif

I agree , a great eyepiece.

I had both BIG ones, a 31 Nagler and the 41 Pan and after some time I choose the 41 and sold the 31.

My favorite eyepiece for use in my 9.25" f/10 cat, and my 127mm f/6.7 refractor!

Gratz on the acquisition. I've always wanted one but can't really afford one now. frown.gif

I owned one once several years ago but it was too heavy for me.  Nice views though.

I owned one for a short while. To get enough eyerelief wearing glasses, I had to unscrew the cone which leaves only a bare painted metal volcano top, a design neglect in my opinion. Great optics I agree.

   That was the first Televue that I bought. My goto eyepiece for widefield now. I was kind of surprised by the size too, so much bigger than my old 40mm Celestron eyepiece.

I love the 68* DOV in the Panoptic series. I only have, 19mm, but have the Meade version in the 28 and 34mm. Someday I will get the 24mm Pan when I can afford it. Never see on in the used department.

Place that does a lot of outreach has 2. The outreach one gets fingers on the top lens - we have tried but so far 100% failure.

The little ones feel for the eyepiece, get fingers around the outside and thumbs on the inside. Guess it gives them a good grip. jawdrop.gif So far I know of nothing worse found on it then finger/thumb prints. thinking1.gif 

 

You honestly stand there cringing and shaking your head, very few realise the cost of them. First time we had one we tried and after 30-40 minutes realised there was no hope. it was either bangbang.gif  or BeatingADeadHorse.gif

Strange but after 4 months we no longer get bothered foreheadslap.gif

 

They are not mine, I do try, and the place just accepts that fingers, more often thumbs, will get in/on. Actually need to ask who cleans them and how often. Strange world at times.

I have a 41 mm Pan, 35mm Pan and the 31 mm Nagler.  They're all fine eyepieces but the 31 mm gets the most use. If my scopes were F/10 instead of F/5-F/7.5, I'd use it a lot more.

The public program at Lowell Observatory owns three of the 41 Pans. We use one in the 24" Clark, one in the Meade 16" ACF and one in the new Planewave 24" CDK. The EP is outstanding in all of them. Of course, all are long FL telescopes.

 

The EPs do get fingerprints on them from kids and adults alike, but they are cleaned every time they are used as are all of our eyepieces. All of these modern coatings really stand up to repeated cleanings with no visible artifacts, some thru hundreds of cleanings. This is true of TV, ES and Baader, all used in our program.

I see Pan 24-mm come up every week, either here or Astromart. Place a "wanted" ad and no doubt you'll get some offers.

Hi all I really like the idea of this eyepiece but would really like it if someone could let me know if when slurping(tech term!) through the heavens there is any obvious distortions to the view that would impact negatively to the star surfing experience? This would be a very nice partner to my Nagler 20mm t2 if the views are distortion free like that wonderful EP is. Thanks in advance to any who would care to comment.

I don't notice huge amounts of distortion.

Do be warned that on faster dobs, your pupil may not be able to fully utilize the exit pupil of the 40P, especially if observing from a light polluted location such as your backyard.

First time I've heard that the 41 does not perform well at f/7.5! I've always heard the opposite. That it was a good performer at even lower focal ratios. Could you explain further?

What I said:

 

"If my scopes were F/10 instead of F/5-F/7.5, I'd use it a lot more."

 

The reason:. At F/5, the exit pupil is 8.2 mm, at F/10, the exit pupil is 4.2mm. Though my dark adapted pupil is somewhere around 7.7 mm, such large exit pupils are rarely useful.

 

4.2 mm exit pupils are more useful..

 

The 41 mm Panoptic is very sharp in fast scopes..

Probably a nice 20.5mm with a 2x Barlow.

Big, heavy and bulky with a significantly narrower field that the 21mm Ethos.

Tried to love it (twice), but couldn't get past the vignetting. Otherwise great

How fast?

 

With a 41mm eyepiece, the actual focal ratio of a fast scope depends on the observers dark adapter pupil. A couple of years ago I measured mine at 7.7-7.8 mm. For me:

 

41mm/7.7mm = F/5.3 

 

That's almost s perfect fit for the F/5.4 TeleVue NP101

I put the Pan 41mm yesterday in my NP101. It was glorious.
