Hi All,

I have M50 and it is a great camera with low noise, but the problem is that for some reason it wants to send CR3 raw images back to PC and CR3 is not supported by Ekos. There is a setting in the camera to fall back to CR2, but for some reason, it is disregarded.
Was anyone able to get Canon EOS-M cameras working with INDI and Ekos?

It might be something as simple as adding "cr3" to Ekos.. which I just did. On next nightly test to see if it works.

Unfortunately libraw doesn't yet support CR3 format.

Looks like LibRaw devs are promising to add support for CR3 this autumn. Another way of dealing with this issue is to force the camera to save in CR2 format. The camera supports this feature but for some reason, INDI still receives CR3 format.

I have an original EOS-M which connects to Ekos, but Ekos cant trigger or control it. Which is weird. I have read somewhere that Canon have disabled USB control on this particular model which is a pity. As you say they are a great little camera, low noise and light.

My question is if gphoto via Ekos can see the camera and can populate most of the camera information, maybe full control is possible? Would this be a question for gphoto developers or indi developers??

I was trying to use my camera couple of months ago and if I remember correctly, I was able to get gphoto to take images using command line but I had to upgrade to latest version of gphoto. With kstars I was able to take images but they were not showing because kstars does not understand CR3 format.

Hi avarakin, what about fits format? Can you get it to spit out fits files??

For this to happen, Ekos needs to understand CR3 format. It is using libraw for reading raw images and libraw does not support CR3 format yet.
I posted a question on libraw forum about CR3 support. They confirmed that it comes soon. Once it is available, it would be a matter of compiling Ekos with latest libraw.

Where did they confirm that? From Github issue page there is very little activity.

Resurrecting this thread since I think I have the same issue. I have Canon EOS RP that also outputs CR3 files and have the same issue with LibRaw support to decode the image.

I've noticed that there is now a public GIT snapshot that now supports CR3 files: www.libraw.org/news/libraw-snapshot-201910

I believe have the latest PPA INDI Nightly Build installed.

Thanks

Hi all I did an update late last week. Tried my Canon RP. Everything seems to work ok via USB. Can trigger camera. The fit file transfers ok. I have not tried imaging with it yet as the weather here in Australia is very bad at the moment.

The next thing I'll try is wifi connection instead of USB. See if I can eliminate another cable from my rig.
