New 16mm - 8mm Zoom with constant 66° field
      #5448509 - 09/30/12 01:48 PM

I am extremely surprised no one has screamed it out all over the internet already, since this has been something yearned for over and over again whenever the future of zoom eyepieces were discussed here:

A 16mm - 8mm Zoom with 66° constant AFOV. Also LER for eyeglass users. All for about $500.

http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/5447882/page/0/view/collapsed/sb/5/o/all/fpart/1

So, now I've done the screaming.


Clear skies!
Thomas, Denmark

Yeah, I just noticed this morning over on AM, seems very exciting indeed, would be perfect as high power zoom in an 8" SCT. If it is indeed in the same class as the Leica ASPH, i.e. Brandon class, it could instantly replace most of my orthos, and with more field to boot...

If I hadn't just sprung for a Leica ASPH I would be all over this one. I may still eventually try a pair for binoviewing though.

Sounds amazing for Newtonian owners.

I have grown to love zoom eyepieces suddenly after all these years.

For a truely well-corrected field, Newtonian users would need to put this Zoom into a Paracorr. Will someone please buy one and let us know if it will work in a Paracorr and at which setting?

It should be nice for planets and DSO in my 10" f/4.8 Newt: 75x-150x native mode, 150x-300x with a 2x Barlow. If I had a pair for binoviewing, with an OCA, that'd also be about 150x-300x.

Than it would still not replace XO's or ZAO's.

The most interesting thing is the admission from the vendor now that the Leica ASPH Zoom "sucks a bit". I would LOVE a high quality zoom eyepiece with these specs but really, since when was Meopta a "world renowned" eyepiece company?

And how long will it be before someone sources these exact same eyepieces at a considerably lower cost?

Meopta is well regarded in binoculars and other military optics.
Also the machined adapter (for astro use) custom made by APM has to cost some more money.

Well that is certainly true. So it's a $110 adapter.



I don't know anything about Meopta but I DO love the specs...

I remember owning a photographic enlarger for B/W in the late 80's made by Meopta including lens, solid east block work but not outstanding....
I would wait for some user comparison between the Leica and the Meopta before jumping on it.

B & H has a 20X-70X Meopta Zoom in addition to the 30X-60X. David

Well, in an f/4.5 scope if you don't put it in a barlow it does "suck a bit" at the edge, especially if you look at what you paid it - I don't think anyone else has ever said otherwise.

That's why mine is really only used with a barlow (either a VIP yielding 1.65x or a Zeiss yeilding 2.3x) unless it's used for traveling with a travelscope and just one eyepiece.

I have no doubt that the edge correction can be better on that zoom in a fast scope. That doesn't mean that it can beat Baader Genuine orthos when looking at Jupiter or when pulling in faint minute galaxies, which the Leica can.

It'd be interesting to see how well it'd perform against #7466 and #7467 Nikon zooms, though (the Nikon loses against the Leica but can be used in a bino, and then on planets etc. it wins against the cyclops Leica).

Wow exciting new zoom in the market, the zoom eyepieces have really come of age after being ridiculed for the longest time.

Best,

Has anyone here on CN used this new zoom eyepiece yet? I mean, besides Herr Ludes. Is there a first light report?

As much as I would like to try one, I'm tapped after springing for the Leica ASPH. I would love to hear a report though, especially in a binoviewer. Especially in a binoviewer used by someone like me; i.e. almost a cyclops due to such a narrow IPD.

Searching the net I didn't find a report/review. The specs do look interesting, but there will not be an appreciable response unless a "brave soul" will get one to be the first reviewer. How about you, Tammy?

Speaking from experience I've started my "zoom career" only after having seen the report by Allister St. Claire here on CN (Comparison of 4 zooms). Something like this will be neccessary to get the Meopta zoom started. Perhaps the Leica ASPH zoom also would be almost unknown unless a "brave soul" like me would have given it a try.

Tammy is a "brave soul." He really should lead the charge on this one. The Charge of the LIGHT Brigade?

I would be more excited if it's price were around $300 AND if it were designed as an astronomical eyepiece instead of a spotting scope EP that requires the adapter which will put the field stop way above the focuser so it will need lots of in-focus.

Needing lots of in-focus might necessitate an OCA or Barlow to come to focus. Then we need to be concerned about the quality of the OCA or Barlow. (Although this seems to work out fine when I binoview planets or the Moon.)

Also, maybe I wanted a 16mm-8mm Zoom, not one that is effectively 8mm-4mm. I'd rather use something like this natively if at all possible.

With a 2" adapter the in-focus requirements will not be large, may be only 5mm. But the 2" format will cause problems for bino viewing which otherwise would be an advantage of this zoom due to its slim body.
