Andrew created a new topic ' QHY5lll 462C Stream Recording Issue' in the forum. 4 days ago

I had an opportunity to use a QHY5lll 462C planetary camera the other night. It works well for capture and live view works fine. However there is a major issues with SER recording. After the recording stops the camera is put into a state waiting for the buffer to offload and save the recording. I gave it a lengthy amount of time to finish, but it never saved the file or became responsive.

Astroberry installs the stable releases for the best overall experience. If you wish to experiment with the nightly for the latest beta features, you can compile it for yourself locally.

You are rotating the RA and not Dec, Yes?

No. FOV is determined with focal length and sensor specs. The whole crop factor thing only applies to photographers trying to match an FOV in relation to a standard film dimension. The concept doesn't apply to astrophotography.

The driver could be out of date and needs to be recompiled with the latest indilib. I suggest reaching out to Radek Kaczorek about such issues with Astroberry, or leave a post on the Astroberry section of the forum. www.indilib.org/forum/astroberry.html

Just select the camera and guide scope combination in the alignment tab. The PAA will drive the mount and EKOS will take the captures required for the process.
ST4 is only used for guide pulses. Alternatively you can ditch the ST4 cable and send the guide corrections through the mount driver (select driver instead of On Camera). That method is called pulse guiding, and is usually preferred over the old ST4 standard.

There doesn't seem to be a way to manually generate WCS information from within the FITS viewer. So I would like to see a new function added to the FITS viewer to generate WCS information when none is present for use with the center telescope, show gridlines and object features.

I've never been clear on what is required to have WCS information available in the FITS viewer. Enabling auto WCS in the options doesn't seem to do anything, at least not when imaging with a DSLR in Native format. I would like to reliably use the Center Telescope feature, so if anyone can comment on best practices, that would be great.

Thank you.

I believe a driver already exists for it called ASI Power.

The period seems too short to be periodic error. My guess is vibrations, possibly wind.

When setting the Telescope focal length on the Mount Tab, you must click on the Save Telescope Info button for it to be applied. Verify it is correct with expected FOV in the alignment tab. It should update the telescope info in the INDI driver at the same time, so save the INDI driver configuration for next time.
Simulators aren't particularly useful for testing the polar align assistant either because by default they don't have much, if any, error.
Do, take the time to get your real mount, camera and guide camera connected and working and try it with real stars. 90% of the time, failed solves have to do with missing indexes, incorrect telescope and camera information, wrong scope/camera combo selected, underexposed frames or bad focus. There are also different solver profile defaults, try them all to see which works best for your equipment.
Sometimes it helps to uncheck Use Scale in the options. This will be slower, but more reliable if your telescope info is inaccurate. Once it tells you what the focal length truly is, you can save the updated telescope info and re-enable Use Scale.

There is a mount control window built into KStars. Should be accessible form one of the toolbars.


If you are looking for an external application, then look through the list of INDI Clients. For example, programs like Stellarium can control an INDI mount. If you are using EQmod INDI Driver, there is also a Linux application called EQModGUI.
