At the same exhibition yet another design of an Alt-Az telescope mount with an optional (limited angle) field de-rotator, obviously aimed at easy and lightweight portability as well as at a short start up time (from unpacking to first capture said to be less than 10min).
The website gives no adequate impression of the complete mount but only shows its components.

My impression looking at the mount was that of an high quality industrial product - with fast and almost noiseless slewing capabilities and an interestingly designed hand controller.

Just having looked at it i can say nothing about its performance and precision of tracking.
Until now computer control only via ASCOM. I suggested they (the producers) should take a look at KStars/EKOS/INDI. ;-)

Hi Andreas,
thanks for Your information.
I had come across their homepage a couple of months ago, and after Your hint, returned there.
It does look promising. However, they seem to be still working on their beta version.
Definite technical data I could not find and INDI support is not mentioned, either. ;-)
So, at present, it is not really an option for our publicly supported observatory. :-(

We are still investigating on the amount of work and money that has to be invested in the change from stepper to servo motors.
Until now no other servo controller but the Sitech Controller II has shown up but at least we found an installation in Germany which we contacted in the meantime.
In case we decide to go for the SiTech we will certainly tackled the driver issue! ;-)

Does anyone know of an INDI compatible servo controller for a heavy duty mount (> 100kg optical load)?

Until recently the mount of our public observatory has been driven by 4A stepper motors and a Littlefoot stepper controller. The latter has given up working and we are looking for a new controller.

Since the maximum slew speed with the steppers is only about 60x we intend to change to a closed loop servo motor system such as the [url=http://www.siderealtechnology.com/store.html[/url] (scroll down to => Servo Controller II ). However, the SiTech Servo Controller II at this time seems not to be supported by INDI. (There is a document on the Sidereal Technology Servo Controller Command Set which probably could be the base for driver development. ;-) )

If anyone has any experience with the SiTech or any other (preferably INDI supported) servo controller please tell us.

No, I have not got the Firewire cam to work using video4linux (v4l2). From what I found in the internet there is no support for this camera in v4l.
However, using Coriander as standalone application I managed to capture planetary video streams in Kubuntu.
For EKOS integrated functions such as guiding I instead use a QHY Cam.

Hellriegel created a new topic ' TIS DMK21AF04 (firewire camera) - functional in INDI?' in the forum. 7 months ago

Has anyone a working installation of a firewire camera? Specifically using the above mentioned DMK21AF04?

The camera is functional (Kubuntu 16.10, kstars-bleeding, last update) using the Coriander Software . Coriander receives the raw video frames, displays and saves them to a predefined directory.
However, trying to propagate the video stream (in coriander) to video4linux fails with

Error: unable to open device. VIDIOC_QUERYCAP error 25, Inappropriate ioctl for device

The same error appears when trying to connect to the DMK21AF04 in EKOS.
I don't think it is an INDI specific problem, so I don't add any log files. ;-)

If anyone has a working installation I would appreciate any hints on what to try.
