Hi all, my experience has been this. A few years ago i purchased a QHY163C. Initially everything was fine with using it with indi, but then QHY did a driver update and i was never able to get the thing to work. Even the cooling oscillated.

I rebuilt my computer(s) RPi4, tinkerboard, even my laptop, nothing helped.

After talking to QHY, their first response was does it work with Windows 10. I dont use windows so was never able to test it. It basically got to the point where i had to sell the camera because i just could not acquire or download photos.

I eventually bought a ZWO ASI 071 and have never had an issue with it using the same computer(s).

ZWO are on top of their game when it comes to drivers, but i suppose they have an interest in making sure things work under linux because they sell the ASI-AIR. QHY on the other hand, do not really seem to care about those who use anything linux.

Just my experience.


Hi Rosario, yes i did.

I just had the wires going into it the wrong way around. I should use my glasses when working with GPIO's :-)



Hi sywong2000, great job.

I did a similar thing a while ago, but not a neat as you build. But i also added a small fan which keeps the rpi4 cpu temp in check.

See images.

pixinsight is pretty good at combining many images into a mosaic.

I have used in a few times in the past. see below

Hi all. It's summer here is Australia so it's Orion imaging time. After a session last night of imaging the house head I thought maybe it would be great to capture a mosaic of Barnard's loop.

But I didn't think of creating my sequence file last night when I was set up. I don't use a rotator so I very rarely change the camera orientation.

This morning I was trying to create my mosaic files and obviously you can't because the camera rotation is unknown and you need to solve once to get this data.

Is there anyway to use my previous WCS and camera orientation data to build the sequence file without having To run the solver? IE offline using your previous sessions data as a starting point.



Hi John, have you been able to capture anything yet?

I have the Canon RP. I'm running KStars with Raspbian Buster on an RPi4 a my stable setup. I have no issues with my 550D, but when i try to use my RP it wont download the image.

I have set my shutter release w/o lens as i use my RP on a tracker with manual lenses and it works fine.

I think the issue with KStars with Raspbian Buster on an RPi4 is libraw2.0 has not been implemented yet. I am assuming that because Canon uses CR3 RAW format on the mirrorless cameras, there is still no way to convert a CR3 RAW to a FITS in Raspbian so KStars can do it thing.

When i use my RP on my Asus Tinkerboard (which runs Lbuntu 18.04LTS) the RP works fine.

regards Petar


Hi Terry, why not try autostakkert instead of Registax for stacking the SER.

It works great.

Then you can use Registax to do your processing.
