Piegiovanni, Maybe Elio can join up with Tecnosky to come up with an affordable "mass" produced  mount for the 120s  :smirk:

does not  APM have a mount to accompany the 120?

 

how about the UA mounts?

-my UA Sirius P-mount works well with the straight through 150MTs,

and even better with my  then over mounted  but rock solid 45* Miyauchis 100mm

A UA Unistar Dlx with their HD bino L bracket should handle the 120s easily if put onto a properly sized tripod such as the Meade field tripod. They're well within the Unistar/ Meade's capacity.
It would be relatively inexpensive compared to many of the options mentioned here.

IMO more stable mounting than a P mount would be necessary at the magnifications that many 120 owners would want to be able to use....100x+.

I have a Unistar that I originally used for mounting my TS 107/700 + Mark V combo weighing approx. 19 lbs with heavy eyepieces. Once I was set on buying the 100mm APO BT I bought a HD L adapter to mount the BT. Since then I have decided to wait for user reviews on how the new 120mm BT performs. I did however try out my refractor and binoviewer combo on the Unistar with L-adapter - the end of the adapter did sag by about 2mm but the setup was very steady with vibrations dampening in less than 2s at a mag of x150. The Unistar is paired with a Celestron tripod with 2" legs. Panning was easy. So such a setup will handle the APM 100mm BT with ease. As to the APM 120 BT - before sending me the HD L-adapter (which is customized to attach directly to the Unistar) Larry tested the L-adapter with his Oberwerk 120mm BT (approx. 45lbs according to Larry) and he said that the weight was noticeable. My feeling is that the Unistar and HD L-adapter should be able to handle the APM 120mm BT (probably 26 lbs with eyepieces).

I've talked with Elio, unfortunately  in this period he is not able to build other  handcrafted  Forks.

Thanks for the attention.

Mad Matt's idea was that Elio should sell his design to Tecnosky, let them build and sell it, and he gets a royalty without having to do any work.

Lot of mounting options...

 

Markus Ludes of APM informed me today that they are working on a new single arm mount for the 100mm and 120mm binoculars. The mount will be made in Germany, not in China by United Optics. Tech design is already at hands of Markus, he's just waiting for prices and delivery time. More soon in the Vendors Forum.

Don't see how single arm is better than this.....works for 100 APO....and 120APO?

 

Fork mount centers weight over center of tripod, single arm offsets weight and is less stable.

Will this work for 120 APO?

:question:

 

According Markus, the Binoptic II fork mount works well with the APM 120 SD APO, too.

 

I guess the main advantage of the APM 100ED/120SD single arm mount is a lower weight factor. For those who want it lighter (personally, I'm not in the as light as possible bandwagon - I'm more the heavy-duty guy  :) )

 

We will have to wait until Markus releases single arm mount tech specs in the other Forum.

If you are pushing the magnification, stability trumps weight.

If price points scale, $1500 USD would seem reasonable for an 80mm version.

 

Also, f/6+ would allow a bit more relaxed CA requirement for objective glass.

 

IMO, not a lot to be gained acquiring an 120mm version of the APM APOs, especially for those of us with 100mm Lunt/APM.

 

Obviously, a bit more exit pupil at the same magnification at the cost of more weight with the 120mm.

 

I'll seriously consider buying 80mm version with 90 degree oculars for travel.

I would love to see a high quality 80mm 90 degree bin.  It would really simplify travel.  Everyone keeps skipping this slot.  Don't know why.

I can only speak for myself: I prefer a high quality 80mm 45 degrees.

Has anybody else been "skipping this slot"?

The Kowa Highlander Fluorite 82mm......extremely sharp in the center....true APO....very portable.....nitrogen purged....disadvantage...expensive...only 3 sizes of oculairs ...edge not sharp.

 

This is my present travel bino.

Got an update from Markus...

He was out last night with the 120's and reports much greater resolution than the 100's on lunar details. He says it's "immediately noticeable" (it's been a long time since I used a 4" and a 5" refractor side-by-side. I forgot how much of a 'jump' that extra inch is).

He also noted a clean split of the Double-Double, e Lyrae,

with "nice Airy discs at X137"...and "Vega color-free at X137". In fact he also said he thinks the 120's are better color-corrected than the 100's (which I thought was about as good as it gets).

 

Mike Harvey

 

It would be interesting to read an indepth comparo of the APM 120 SD and APM 100 ED, both 90°.

 

If I remember correctly a comparative quote of both APM 100 ED 45°/90° versions (elsewhere here on CN), the 90° version was reported to be slightly sharper and better color corrected. Not much but just noticeable.

I guess the same would apply for the new APM 120 SD, too.
