There is nothing better than this.
It's really easy to control and move very very smoothly.

Nice! Do you have a link to the manufacturer's site?

Impressive ratio of weight capacity to mount weight and size!

Tracked it down to a Korean site also,
http://supermount.kr...ge&pcode=sub1_1 . It appears to have more information.
Pricey at 850 plus, but impressive with that C11 on it.
I love this type of mount, but I have never explored the upper end of the carrying capacity of my Sergo Bonilla alt/az and Williams clone of the AYO Swiss alt/az due to tripod limitations. I believe the SB has a similar bearing setup, AFAIK, to the non mount, but I assume the noh mount has been upsized.
The double sided mounts seem to stress the bearings less by allowing use of counterweights on the off side. I use a sliding CW on a 16" dovetail rail to continually rebalance my big binos, and hAve a old gem cw bolted to a short rail for scopes. . The Vixen Porta is very load limited with its single side design.
My mounts have carried large scopes, but either the tripod (most likely) or mount cause extended vibration settling times. I have not tried the C11, perhaps as my pre-move cleanout nears an end, and mosquito season is over, and I upgrade the tripod.

Both products are designed by Mr.NoH but NoH's Mount and Super Mount is different.
Super Mount is previous name of NoH's Mount.
CT-20 is the newest version of Mr.NoH's.
There is no more products by Super Mount.
Also the cost is changed.
If you would like to ask the cost, you should make contact to the NoH's Mount.
I also contacted to NoH's Mount directly and have got this mount.
I think it is cheaper than DM-4 and little bit expensive than AOK.
The internal strucure of the main body of CT-20 is, one side is bearing and the other side is shaped conically.
It makes possible to increase the friction surface and provide really easy to control and smooth moving.
There is no need to use counterweight because of the conical structure.
Anyway, it is an incredible quality as I surprised!
I need only two fingers when I make slightly moving with loading 'C14 with 9mm eyepeice'

$850 + tripod costs.. pass.....
+ DSC's...if any can be installed.
However, weight/payload ratio is very impressive.

Way too expensive for what it is.
TS in Germany have something very similar for a fraction of the price (I bought one)
Yes I am sure it could carry a C11 - mechanically - but frankly hopelessly unmanageable for anything with a focal length longer than 1500mm due to the lack of tracking.
Could you let me know the one in TS what you told?
I could not find the one in the TS site...
It is not C11. It is C14.
It is possible to manage anything with a focal length longer than 1500mm.
Actually, I could manage C14(focal length 3910mm).

C14, extremely impressive. Balance must be critical though through the elevation range. Easily addressed with sliding cw on the off side, etc.
The Korean site has a clever cw addon to offset changes in balance through the movement arc,
My sliding CW on a long dovetail does the same thing, and allows fine adjustment, essential on binos.
What tripod is it on?
Tripods seem to be the biggest factor with my alt az mounts, although the small body sizes of the mounts seem to somehow minimize vibrations after movement.
I agree, tracking is not really an issue on a smooth zero friction alt az, particularly with wide eps, but 50 degree eps are also usable.
Otherwise all those huge dobs would be out of luck!
The short (relative to fl) tubes of SCTs really help with vibration issues too, my 6" f8 refractor is much fussier than a similar fl SCT. A green laser avoids the occasional finder to eyepiece bump, and is accurate enough for high powers.
I have found combining a zero friction alt az with a green laser is a sweet spot for a big scope grab and go, otherwise an oxymoron. I have an aluminum portable poer that lives in the yard, and a bag with an pier head, alt az, laser and minimum ep set. I can also take the bag in one hand, and tripod on a shoulder sling on the other side, if on the road. Adding a big refractor or sct ota just takes a second trip. A Baader Nexstar plate lets me do a similarly easy Nexstar 8 session.
Love alt az mounts, they simplify visual use.

I'm sure that the mount will hold the C14 in terms of it won't break and allow the scope to fall to the ground but how does the mount behave when observing with the scope ?
A near 4 metre focal length is going to be a huge challenge to hand track I would think. Even low power is around 100x.

I was thinking as same way as you before I use CT-20.
I tried to take a part to peices CT-20 as I possible.
The each peices of the parts are very different from others that I have never seen before.
The red color part is azimuth. The part of the very left side is altitude.
I guess there is no others like CT-20 ever before.

Yes but that mounts costs around a thousand bucks. You also still have to add the price of a tripod and saddles to that as well.

how does the NoH mount handle different eyepieces? Must the scope be rebalanced or are there clutches/friction plates like (as I understand it) in the DM-4?
Is it just the mount, or is the saddle included? Is the pier also included like seen on the Japanese Eyebell site? Is that saddle Vixen compatible?
Anyone have any idea whether and how encoders would fit on this thing? Solving that might make this worth a try.
I'm mostly attracted to its size but wondering if the dimensions are accurate (140x130x75 = ~5.5"x5.1"x3") and the saddle would add to that but still pretty darn small... Need to fit a mount with my Stellarvue SV102T (dissembled focuser from tube) all in a carry-on hardcase. The DM-4 or Stellarvue M2c would seem to fit (haven't tied yet)...but barely if at all, this at 3" in its narrowest dimension would help by an inch...
Anyone seen/touched this?
And does it really come in the purple color as on the supermount site? Maybe an Irish kelly green and gold trim? Not kidding on having color choice being cool, but the red with grey by itself is really snazzy.
Im interested but just not sure.
