Not seen this Nagler before...

[JamesF]

Not that I recall, anyhow. Which model is it?

I think that was a Type 1 Nagler

[John]

Yes it's a 2nd generation type 1. The 1st gen ones were smooth sided (no rubber).

[JamesF]

It's certainly an odd-looking beastie.

Hi James, yes, I saw that. Also saw this 2" 32mm on AB&S, not come across this before: http://www.astrobuys....php?view=66407

They were the forerunners of the Panoptics. I used to have the 15, 19 and 24mm ones which were 1.25". The 32mm and 40mm were 2". Again there was an earlier smooth sided version.

Thanks John, I wondered where it came from.

Looks massive against my 9mm T6. They seemed to go for this two inch fitting outside the normall 1.25 inch a fair bit, I am not sure I like it, where is the problem with one or the other. Is there an obvious reason that I am missing for this?

Nice work with the 32mm Pre Panoptic, I have never seen one of those either.

I think they use that approach when the eyepiece size and weight could, for some, justify a 2" focuser even though it's a 1.25" eyepiece optically.

The T6's took the shorter focal lengths from earlier ranges and shrunk them rather cleverly I thought. They also improved the quality of the coatings, some of the glass elements and the eye relief.

The T5 20mm did the same. The T2 20mm Nagler is a mighty beast around the same size and weight as the 31mm Nagler. The T5 20mm is still a 2" but very compact and about half the weight.

[JamesF]

Handy not to have to swap between 2" and 1.25" fittings for the focuser tube too, if all the eyepieces you're using have the same fitting.

James,

Yes I guess that is a good point but it never troubles me to do that but I have to say I have dropped the adaptor a few times, I have one with 3 areas of concrete rash around it's edges. Maybe it does trouble me then.

Still it is what the glass within them performs like that is the most important thing, on that front I don't have any issues.

Talking about shrinking, John, I think this is where ES have capitalized, their ep's are very compact I find. I think they have taken a leaf out of TV's book in more ways than one.

Hi Guys, I see there is now a TV 32mm widefield on Ebay now, 65 degrees apparently, here: http://www.ebay.co.uk/itm/TeleVue-32mm-Wide-Field-/261178918758?pt=UK_Telescope_Eyepieces&hash=item3ccf7a0766

Is that a 2" fitting?

I'm fairly sure it is, yes.

Yes it's a 2" fitting. The Tele Vue Widefields are nice eyepieces but the Panoptics that replaced them are much sharper across the field of view and have better coatings.
