Connecting an ASI 120 MC to mount

jjames

Hello everyone, I recently bought my first camera, an asi 120 mc and now I am trying to connect it to my telescope mount (skywatcher az goto). As a software, I'm using firecapture.

I installed the camera driver, the ascom drivers (platform, driver, st4 telescope) and connected the camera via usb, which works perfectly with firecapture.

However, the autoguiding is giving me trouble, I connected the st4 cable to the camera, from there to the control, and the control to the mount. Alternatively, I tried connecting the camera to the mount directly, but nothing seems to work. I'm selecting ASCOM compatible mount and ASI ST4 drivers. However, the mount is immovable using the controls, anyone got suggestions what I can do to fix the issue?

Sounds similar to the issues im having with the 174. Basicaly i think it connects but it can never calibrate with the mount

Hrm, I did run ascom diagnostics and got this (ST4 telescope):

I searched this on the forum, where it previously was discussed, but no solution offered. Any hints? Drivers, ASCOM are all up to date.

Edit: This might not be an issue as firecapture is running in x32 mode, and the error doesn't occur in the ascom x32 diagnostics, which seem to work just fine.

you don't need to install ASCOM driver if you want to use auto guide under FC

just select "Camera internal-ST4 port"

It's not possible to auto guide an alt az mount due to the field rotation's effect on the calibration.

You are mistaken. It is indeed possible and a feature of my mount. Using celestron ascom drivers and an extra com to usb adapter, it seems to work just fine, just not via the camera's port. However, I'd like to do it all over the camera as I've got two free usb ports only.

That doesn't seem to work either :/ Any other suggestions?
