Astro-physics super-planetary
      #611148 - 09/22/05 01:10 PM

I was just poking around the Anacortes website and saw them listing the Astro-physics super-planetary eyepieces. Are these new? Anyone get a chance to use one yet?

Thanks - Darrell

Darrell,

they are not really new, something more than one year, as I know.

Very few of us have used them. There were some threads or single
posts telling about them.

I recommend you to perform a "search", limited to the eyepiece forum.

Good luck!

Amalia

Darrell,

They've had very limited availablity.

Darrell,

There is a review of these eyepieces on the Company Seven website.

http://company7.com/astrophy/options/apsuperplan.html

The review is very informative, even without keeping in mind that Company Seven sells these.

Thank you Brent, I hadn't seen that.

In addition to Tom's excellent link, there's also some reviews by owners and of course from the man, Roland Christen himself in the AP user group.

The eyepiece was first conceived in late 2002 jointly by AP/Aries at about the same time as the TMB SuperMono was conceived. However, from what I've been following, the glass were hard to make by Aries plus some design changes to Roland's perfect satisfaction . When you think about it, to get eye relief longer than f/l (I think it's 1.4X but can't remember exactly with my 4KB of memory ) plus 45 degree FOV like the ZAO and with only 3 element in 1 group cemented yielding 2 air-to-glass surfaces, you can see why it's plain tough.

I hear there's a huge waiting list for the eyepiece and Roland kept putting the eyepieces together as fast as he can whenever glasses arrive from Aries. So alas you won't see a whole lot of it yet.

Incidentally, I just checked and Anacortes has a limited number of the 6mm in stock.

If I wasn't broke, I'd buy one myself.

Sounds like astro-eye-candy to me! I gather we shan't be wasting our time looking for deals on them on AM?

Well, depends on your definition of "deal". I think there are some people who would buy these at twice the price and consider it a "deal" that they could get em at all.



Unfortunately, I'm not one of em (distinct lack of cash). Allister and I did try to get a set of these for testing when they were first announced, but at the time AP was running some sort of funky call in thing. Evidently they didn't want to start another wait list and let people know that they had XXX sets that would be available first come first serve on (whatever day it was) a year or so back. You had to buy the whole set.

Neither one of us got through in time to get a set.

This is where I really have to hand it to Markus and the TMB supermonos. Those, at least, were readily available. Hopefully, these will be (eventually) too.

Tom,
So, what constituted a "set"?... & what kinda price was the "set" fetching?

Ron, the design is actually 3-elements in 2-groups (i.e. total 4 air-glass surfaces not just 2). Makes for much greater freedom in designing to get all that accomplished I should think

Oops, guess you're right Pete, according to the spec. at Company 7 web site. Originally however, the prototype reported by Roland back in 2003 had only 1 group 2 air-glass surfaces. Perhaps, he had to change the design some what.

Don't know which prototype this might be, must have been before the prototypes that I knew about.

$1500 for six (? I think) focal lengths.

Nope. I looked into it once. I'd like to try one, but the reports of field curvature are discouraging, given my problems with the TMB SuperMonos.

Ron, that one was a bit before I started paying attention. IIRC, by the time the TMB SuperMonos came out, Roland and Valery had decided on the 2 groups.

A buddy of mine has some, and we're getting together at GLSG (Great LAkes STar Gaze) next weekend. Hopefully I'll get to spend some time with them.

Thanks Mike for the confirmation, Mike. I kinna lost touch after I heard about some design changes.

I own one, but I had not the opportunity to try it out for real.
Also it is a high magnification one, 5mm, and I don't own another
(like an ortho) of this focal length. Well, maybe I could compare it
to the Supermono.

All I can say is that the promised eye relief does not seem to
be reached - I found the eye relief to be very, very short (yes,
compared to the 6mm ortho, not to the 5mm XW).

I have been calling Company Seven about them a year ago, and the
man answering me talked about "the AP SPL getting closest to the
Zeiss Abbe orthos". But he did not tell me which other eyepieces
were involved in this comparison. So "closest" can mean anything.

About the Company Seven comparison: There is a big "but" in
this one, as it was only performed on day light. This does not
seem appropriate enough to me to say anything about their
astronomic performance.


There is this test, telling about field curvature, as Mike noticed:

http://www.pteng.de/temp/okutest.pdf


And there is my translation of an European planetary eyepiece testing.
Unfortunately, these results were not really taken serious by some on
this forum, probably for cultural/political reasons.

Some News About Planetary Eyepieces


Daniel Mounsey is preparing a new text about his testing of many
planetary eyepieces. I am quite sure he will include the AP SPL.


On CN there have been some short posts about them, like this one.
As it contains sentences like
"Better yet, the usually lousy seeing from my backyard improved to at
least fair."
and
"I haven't tried a Supermono, but the ergonomics of the SPL seem
better to me - more FOV, more eye relief, and less field curvature.",

I would take this with several grains of salt.

AP SPL, first impressions


A year ago I had ordered something like four AP SPL, but as time
passed by and by and by and by, I cancelled the order and found some
old German and Japanese orthos which make me very happy.


I have always found strange that the AP SPL are sold already more than
a year, but hardly anybody writes about them.
