Nice one.

And wallet trumps majesty for me at the moment!

A well executed Abbe design is a beautiful thing to behold IMO. Unfortunately, those really well executed ones, like the 6mm ZAO-II I have, it is the other way around and the TVs cost less than it

It's odd you make this claim when you previously indicated you don't have TV eps

You also previously got your wires crossed about the costs making comparisons with XWs

Now you are introducing new variables with top shelf ZAOs

When you strip everything away you seem very determined to promote Televue eyepieces even though you previously claimed to have no vested interest.

Bill just knows rather a lot about eyepieces.

Wow.
OK, I "choose" the 5mm XO shown on the cover.
Where can I order it from?

Books are not subject to independent peer-review akin to scientific journals

The key criteria to book publication is the publishers confidence in achieving sales to at least cover their costs - sorry that is the unpleasant reality otherwise they don't stay in business.

Many people know a lot about eyepieces - whether we have the time or inclination to write a book is a separate issue.

Conversely, simply because one writes a book does not automatically denote expertise and anyone familiar with voire dire in the testing of expert witnesses will understand this.

Eeehhnn

I think I am suffering from PTSD

I can't even remember how many book proposals I have had rejected from publishers over the years. I slowly learnt the important ingredient to securing a contract was being able to state that the book 'once published' would be a mandatory prescribed text for students doing a course

True. Linking to the book was my clumsy attempt to convey the high standing Bill has on Cloudy Nights, where he is one of the go-to guys on eyepiece questions.

Anyway, he has started a new thread on his first light review of all three DeLites and they sound very good (if expensive ) with plenty of references to Tak LE and Abbes.

Yes ...I have read the review ... he certainly puts them ' up there ' with the premium counterparts.
It's nice to here a favorable report on a new line of eyepieces from someone with such experience... over 45years in the hobby.

Not knocking them, but for the money they ask here in AU ...I myself would go down the TAK LE road .... and still have change.

I read a few reviews of the LE eyepieces last night and certainly wouldn't mind trying the 7.5mm - anyone want to lend me one?

Mind you, I read that the 5mm and 7mm LE's have/had flaring issues on the Moon, which is unacceptable at that price. Hopefully it's been addressed in current production models?

Not wrong. I want to get a 10mm and 14mm Delos but at their prices. Have been keeping an eye on the classifieds so hopefully something comes up soon. There's a 10mm Pentax that's just been listed but I really want the Delos. What to do!

There's not much difference between Delos and XW, although above 10mm the XWs show field curvature in a lot of scopes whereas the Delos don't.

I had the Pentax XW 10mm and it's an excellent eyepiece. I'm sure you'd be happy with it.

Again - If I am not mistaken - I think we have all come full circle once again on the original point about orthos v Televues divided by their relative price

The 5mm LE is fast becoming one of my favourite eyepieces for planetary observing - I think some regard it (and/or the 7.5) as the best in the entire range provided they are suitable to the focal length of your OTA

I can't say I have noticed any "flaring" in my 5mm but I suspect there are lots of factors that could potentially cause this perception in any eyepiece

I am not trying to beat up bussiness for Claude (although he is a very nice guy) but in case anyone is interested or don't already know - he does have the LE's on special right now - essentially he is selling them for the same price in AUD as what they sell overseas in USD - and he is doing this despite the drop in the value of the AUD

I had the 5 and 7.5 LE many years ago and it was nearly impossible to do any lunar observing with them as a large splotch of flare would wash over the FOV and take away all the contrast. Some folks corrected this by making a gasket with an 8mm hole in it and placed that over the field lens. But I recently reacquired the LEs and my current 5 and 7.5 still flare, but it is very minor and of course only on the Moon. Minor enough to not matter. So IMO, given the difference between my old ones and the current ones, I presume Tak addressed this issue at some point. So I guess luck of the draw which you get if you buy used.

No arguments from me

Like I said in my post on the other DeLite thread wherein I disagree with Wavytones

I hope everyone takes on board all these comments and start buying Televue DeLites and in the process decide to sell their old eyepieces - especially Takahashi LE and Orthoscopic eyepieces.

First serious review of all 3 focal lengths by Bill Paolini:
http://astronomyconnect.com/forums/a...light-review.1

These may become "classic" binoviewer eyepieces. About half of my customers have bought pairs, which surprised me a lot.

The DeLites are derived from the Delos, which, in turn, were derived from the Ethos. Color is neutral and spot size is smaller than Plossls or Abbe orthos. When shorter focal lengths come out, these will be premium planetary eyepieces. Of course, for focal lengths exceeding 1500mm, the 7mm would be a reasonable planetary eyepiece.

Too bad about the exchange rate.

We need Tele Vue to have one of their sales.
