Today, I took the nine-question email survey.

All I want them to change is to lose the accursed undercuts.

We'll see.

I did it too, I had the impression that this survey was a sort of justification for a price increase, lol

Yeah, I noted the undercuts as not a good thing too. The survey seemed very prescribed, and didn't give the opportunity to make other comments. I'm not sure what they would gain from it- other than to get our email addresses if they didn't have them already... ;)
Telescopes: 12" f5 dob, Celestron CPC800, 150mmf5 Celestron achro, Tak TSA102, TV76, ETX125...
Binos: Steiner Wildlife XP 10x26, Swarovski 8x30 Habicht, Zeiss SFL 8x40, Vanguard Endeavour 10.5x45, Fuji FMTR-SX 10x50, Tak 22x60, Orion Resolux 15x70
Eyepieces: way too many (is that possible?), but I do like my TV 32mm plossl, 13mm Nagler T6, 27mm Panoptic and 3-6mm Nagler zoom, plus Fujiyama 18mm and 25mm orthos and Tak 7.5mm LE

I would be shocked if that ever happened.
It would imply they acknowledged something was wrong with the undercuts on all their other eyepieces.
It would create pressure on them to change the eyepieces they already make, which would create the problem of obsolete stock and a mixed inventory.
A mixed inventory would require them to discount the ones with undercuts and carry a lot of inventory they can't afford to stock.
So the best we're going to see is the beveled lower edge of the undercut on the barrels.

I fixed the problem of the undercuts by filling in the undercut with copper tape. Unfortunately, that doesn't fix the problem of the brass split ring binding in focusers, adapters, coma correctors and Barlows.
The brass split rings are the source of many insertion and removal problems for accessories.

If this doesn't work (below), just go to their website, enter their blog, and click on "televise eyepieces: what's your opinion?"
https://televue.com/televueopticstalk/2 ... r-opinion/

Have fun!

No it was not :)
Nor does it seem that what they think is important matches what I think is important.

It would create pressure on them to change the eyepieces they already make, which would create the problem of obsolete stock and a mixed inventory.
A mixed inventory would require them to discount the ones with undercuts and carry a lot of inventory they can't afford to stock.
So the best we're going to see is the beveled lower edge of the undercut on the barrels.

I fixed the problem of the undercuts by filling in the undercut with copper tape. Unfortunately, that doesn't fix the problem of the brass split ring binding in focusers, adapters, coma correctors and Barlows.
The brass split rings are the source of many insertion and removal problems for accessories.

Whilst I like my TV Naglers, like many others, I find the binding of the compression ring in the undercut quite irritating.

The undercut binding problem is so easily fixed at manufacturing level. They could retain the undercut but instead of a hard edge to return to the full diameter, machine a gradual return, a taper. Then the compression rings would slide up the taper without binding.

And that is exactly what Tele Vue did--beveled the lower lip of the undercuts on the barrels. It didn't eliminate the problems created by undercuts, but it did help.
