Nobody in their right mind would pay TH's prices for ES eyepieces. In the USA they are listed at $899 so even allowing 25% import costs it's going to be much less expensive to import these. Still it's going to be around £700 imported which is a fair whack  :shocked:

You could buy an Leica ASPH zoom for less and it would do a lot more. If you are desperate for 120 degrees the ES is currently the only game in town though.

how do these things run against TV eps in fast scopes?...never used one in mine, have to wait for crash as he will steal my fastest scope crown! :icon_king:

I've never seen or used one but there are a few reports on the "Cloudynights" forum on them which seem to be generally favorable. The main complaints seem to be a slightly fuzzy field stop (if you can see it !), that the weight is more than a Nagler 31mm and that the eye relief is pretty tight.

Seems like a marketing driven exercise to me. When I had my 3.7mm Ethos SX, I bought it for the focal length, contrast and sharpness, not for the 110 degree fov. 80 to 100 is plenty!!

I think the whole idea of these EP's is getting a little too much - can someone please help me to understand this !!! -  I know that you only get what you pay for - can someone on here give us an insight into these expensive pieces of glass. I only have the Hyperions and a set of 4000 Meade plossls which I find great to use, I think the next step up would be the Naglers (not sure that's correct - can someone who has used these different EP's give some advice and possibly a little bit of a league table when it comes to quality of EP's).

The EP's I have, I find them to be excellent  in my long focal scopes, I know that when focal lengths shorten - the quality of the EP becomes noticeable, I remember having one of the early Moonfish EP's and even with the dodgy edges, I could put up with the quality.

I know that you get increased contrast, edge sharpness, but has anyone done a comparison under light polluted skies with long focal length scopes - please tell me that there isn't much in it??? - or, if there is, can the extra outlay be worth it???

I think if I had a spare grand - as others have said - the last thing on my list would be 1 EP!!!!

I've been into this Astronomy lark for the best part of 25 years - is it me - or do I need better EP's!!!!

Paul.

EDIT - Just a thought, say if you bought one of these, then you dropped it onto the nice shiny concrete floor - doesn't bare thinking about.

I also use long fl scopes Paul and these are far more forgiving on eyepieces so there is no way I could justify spending this amount of money on just one with the kit I have. As you say faster scopes show up ep quality issues but I must admit that this seems to me to be technology for technolgies sake. Im sure there are a few eyepiece junkies out there who would willingly go for something like that, good luck to them but I cant help thinking theres a great deal of marketing hype for stuff like this, creating the market so to speak.

Oh it'll blow those tv's of yours out of the water. better upgrade Calv. I'll pay postage only for that 13mm of yours. :evil:  :eek:

Edit: better yet, I'll pick it up and spend the postage on a couple of pints 

Edit 2: £1000, one ep or 5 northern lights experiences :D

I think eyepieces are becoming quite hyped up these days with many features that people dont want , dont need and will never use but with clever marketing everyone gets hooked. Its like buying a car these days and paying extra for alloys wheels and metallic paint, neither are essential but marketing have out such things on a pedestal and called them luxuries that we cant live without.

With eyepieces we are sold features we are told we must have.

- A 120 degree field that I cant see,

- argon or nitrogen in my eyepiece

- waterproof to 100ft

- 3inch fit

Lots of gimmicks these days, becoming like tasco scopes in the 80's selling 60mm fracs with 600xmag

Wish they focus on decent eye relief on 100degree fields and less coma.

Cheers

This does seem to be a case of ES wanting to out market Televue. It's not something I will be following, much if it financial, but also because these eyepieces are just too big to be practical in most circumstances I would use them. Unless and until I won the lottery and have a permanent observatory I can't see a place for this.

As said, give me 20mm eye relief in an 80 to 100 degree afov with Delos sharpness, don't need anything more, certainly not a 3" focuser!

EDIT: actually, with our weather, the waterproof spec is probably the most useful ;-)

I think thats why Tele Vue introduced the Delos  :smiley:

The point is that there is something for all tastes and budgets these days. Take your pick of what works for you  :smiley:

When I started in the hobby we had Huygenians, Kellners, Orthos, Plossls and Erfles and that was it. The latter three designs were not exactly cheap back then either   :sad:

How did glasses wearers manage back then as the above designs all have poor eye relief in shorter focal lengths ?. Barlowing I guess.

Was it the same hunger for wide field EPs too at that time? I have the impression that many EPs at that time were named as Erfles, the known wide field EPs, but many of those were actually other designs, such as König, Goerz, etc.

I dealt with it by having younger eyes :wink:

I agree John,we are spoilt for choice these days and I must admit the Delos range are stunning eyepieces its just a shame that they are 72degree fields.

I must say though that if I wasnt allowed anything else but Delos Id be more than happy

cheers.

- waterproof to 100ft

Perfect for those relaxing evenings observing from the bottom of your swimming pool  :grin:

Maybe it's just me, but the advertising line they used to use "Every eyepiece tested waterproof to a depth of 1m" kinda puts me off. I don't really want to buy something that's been dunked in a bucket of water!

all the best

Tim
