Hello,

I am using Ekos on a Pi 4, and most everything works fine except I cannot take raw pictures on my Canon RP eos.

I always get the following error in INdi control pannel:

[ERROR] Exposure failed to parse raw image.
[ERROR] cannot open /tmp/indi_7suady: Unsupported file format or not RAW file.

As for the Ekos message I get : CCD capture aborted. Capture failed. Check Indi Control Panel for details.

If I use JPEG everything works fine.

Fits works fine as well except it is always in B&W.

My rig is :
Ioptron CEM40
Pi-4 with 4G ram
Celestron C9.25
Askar M54 OAG
ZWO ASI290MM mini
Canon RP

Also: RAW works fine when using INDI in remote.

Has anyone run into this problem before?

Thanks!

Why aren't you using Canon DSLR driver? Also try to see in Options if Force BULB is on/off

Hi Jasem,

Thanks a lot for your quick response!

I tried the Canon DSLR driver and I have exactly the same problem.

Also, the BULB option is ON, and my Canon is also set to BULB. Beyond 2 seconds everything works fine with the exposure. Bellow 2 seconds I use M instead of B and it works all right too (with Bulb option OFF in INDI).

What is really weird is the problem does not appear when controling my PI in remote.

Hello everyone,

Being absolutely unable to solve this issue on my PI-4, I decided to roll-up my sleeves and start all over again.

This time, instead of using Astroberry, I started from scratch using the Ubuntu 21.10 desktop.

I installed all the necessary packages (Indi, Ekos, VNC, etc).

Also, I opted for an external drive (in this case an SSD) instead of an SDCARD (Ubunru 20.04 does not allow that but 21.10 does).

This way I have better perfomances and a lot more space on the drive (at least with the material I had in hand).

After installing everything and swearing from time to time I managed to make almost everything work again.

And guess what: my problem dissapeared. Moreover, my colors are now 14 bits as they should have been, instead of only 8 bits as they were in my previous setup.

I cannot tell which of the modifications hit the nail but one of them did.

However, I am now stuck with a problem I didn't have before and that I will talk about in another post.

Regards,

EL

Hi Erik, that's interesting.
I also have a problem with only 8 bit images. The Ubuntu used is 32 or 64 bit?

Thanks.

Hi Thomas,

My Astroberry installation was based on Raspbian 32 bits, whereas my actual Ubuntu 21.10 installation is 64 bits.

Could this be the reason why I had 8 bit depth instead of 14 bits for my Canon RP?

Could be...

Hi Eric,
I do not know. I will try Ubuntu 64-bit and give the result.
