We would like to introduce our handmade new mount 'CT-20'.

It's getting popular in Korea and Japan.

It is very useful as a 'travel mount'.

We are asking encoders to Astrodevices now.

We would like to sell our products in USA and other countries.

We are planning to start selling from around April this year. 

Could you give us some opinions of Vendors?

Astronomics and Agena Astro are TOP vendors to the US amateur astro market. That's an interesting product and partnering with Astro Devices is smart.

Those saddle BOLTS will damage and ruin the telescope dovetail bar, please use a CLAMP BAR like this:

Also would be "nice to have" adjustable  Celestial Setting degree Circles for the Azimuth and Altitude axis that move in the proper direction.

If encoders, are added, it would be desirable to have a scheme that doesn't add to the lever arm.

 

E.g. adding encoders to the ES Twilight 1, makes both the alt and azimuth "lever arm" 25mm longer in

each direction, i.e. adding the encoders makes the scope less stable.  Basically adding encoders

ruined the usability of my Twilight 1 as far as I am concerned

 

Some mounts, e.g. DM-6, and others have the encoders "internally", which does not affect the

stability of the mount.  It appears the AYO Vamo Traveler (I don't have one, just looking at

pictures) have the encoders mounted in such a way that doesn't add to the lever arm, even

though they are external.

 

Please don't let the encoders increase the lever arm.

Interesting payload capacity. I hope it is affordable.

Eaxactly. Those bolts and and clamp look flimsy for something that is expected to carry 20kg of load. Even their C30 that carries 30kg features that same bolts and clamp. But maybe it is just the picture.

I just checked the price, USD 650 for the CT20 and USD 800 for CT 30. With that kind of price, the clamp should look better.

 It is difficult to describe ct-20 as text. So I  have described it as a photo.

The internal structure of the CT-20.

A and B are slightly cone-shaped.

When (1) is turned, part B moves upwards.

Nice illustrations for the internal mechanism!  That being said, I think people were not concerned about the robustness of the mount itself, but rather the bolts on the saddle that lock down the dovetail plate which judging from the pictures can mar the side of a dovetail plate. Also the saddle plate itself looks a bit too skinny to safely handle something like a C14.
