Autoguiding Celestron and Skywatcher Alt-Az Mounts

Filed under: Animations, Software, Sun — Dave @ 10:44 am

DSSR now has the ability to autoguide certain brands of alt-az mounts to allow you to track and record the Sun, Moon, planets, comets, etc.

The guider can guide your mount to within 2 or 3 pixels which is good enough for solar system work. Below are some solar animations that were captured on a Coronado PST on a NexStar 4SE mount.

    • Hi John,
      Follow the ASCOM link at right and install the latest version of ASCOM. You will also need to install the relevant ASCOM driver for your mount.

  2. Hi Dave!
    In the next few days i’ll try DSSR on my NexStar GT mount. I think that only DSSR has the ability to guide it. It is an alt azimuth mount.
    I’ve tried also to set exposure time of the webcam, but it seems that no one correction is made. It’s just my fault or that funcion is not already implemented?
    Thank you very much.

    • Hi Marco,
      If you right click on the Camera button in DSSR you will open up the camera’s property dialogue. You can set all the camera properties from there. DSSR can also control some cameras like Imaging Source where the manufacturer has allowed 3rd party control. You use the Exposures button for these cameras as well as the properties dialog.

      • Hi Dave!
        Thank you very much for your reply. I’ve tried again and the Camera works fine.
        Now I have to try my mount with the aztrack. I hope it will works..
