Eyepiece as per title. 82002 model.

 

They are 31.7mm fit.

Has anyone tried either for astro viewing, mono or bino?

 

With its long eye relief it seems a good companion to the TV 40mm Plossl. I am curious of the optical design & AFOV, of this eyepiece as well as its performance.

Got one now at a low enough price.

 

It comes in a nicely padded box, as ES uses, and in a black velvet pouch, also like ES. A lens cleaning cloth is included.

 

No indication of focal length, just magnifications with the 3 sizes of Celestron spotting scopes. 

 

A fairly heavy eyepiece for a 1.25" 32mm. Eye relief is immense. Its semi-rigid eyecup is a tube the same length as its optical barrel. Too little eye distance wearung glasses, too much with glasses on. Fortunately there is a screw thread for afocal photography, so a screw on shorter eyecup can be used.

 

I estimate the AFOV is between 65 to 70°.

I have one for an 80mm Regal and I think I tried it once in my 8" Dob. Can't remember how it performed though. The ER is very nice though.

Found a B&H link https://www.bhphotov...r_regal_m2.html

 

So it's a 25mm with 32mm eye relief! Beats my TAL 25mm symmetrical. Weatherproofing good feature. 55° AFOV probably makes it a Plossl. Clear sky tonight to try it out.

I think you are going to have to look to e-bay for one. They are not really for sale anymore and it's been that way for at least two years or more. My 80mm came with the LER EP and my 65mm came with a zoom, which is not a bad EP for astronomical. I use it quite a lot and it seems to perform as well as my BHZ.

 

I almost purchased another of the LERs for the 65mm but decided against it. Should have snatched it up.  BTW, I did a comparison with my 28 RKE and it had a similar view in the spotter.

Got mine new on Amazon from an outdoor hobby shop. Spotting scope, binocular & photo retailers are good places to look.

 

This review  http://binocularrevi...eyepiece-82002/ its 18mm "tested" !  So its possible the 82002 is an Ultima Duo 17mm or 21mm as their prices are similar, and both are M42 threaded for afocal photography. The 82002 is gas sealed, nice for outdoor use.

The B&H page with the 25mm focal length is bogus.  The Regal 80mm (F/6) with the LER provides 27x as per their specs and as per other pages.  That works out to 18mm.

Thanks Jon. 

 

Seems the Ultima Duo optics likely then, in a different, shorter barrel to give more eye relief.
