I've set up an Odroid C2 (a small ARM-based box akin to a Raspberry Pi but a bit more powerful) withEkos (part of Kstars) and all the cables needed to connect to a Meade Autostar and a Canon EOS 1000D.  Amazingly enough almost everything worked first time.  The RA and Dec motors whir when asked to and not otherwise; the camera shutter clicks when asked to, and so on.  I'm very impressed.

 

The outstanding issue which I have been unable to solve as yet, is how to ensure that the images are downloaded to the Odroid rather than being stored on the SD in the camera.  Curiously enough, a dark frame ended up in the Odroid's file system but, so far, no lights have appeared.  A bunch of images are indeed on the camera's SD but I'd prefer not to have to remove it after each observing session.

 

This sounds like it should be a FAQ but searching the CN forums hasn't turned up anything.

 

Any suggestions gratefully received.

 

Paul

I would search the Canon EOS SDK to determine the specific USB command(s) to download the CR2 images.

Try these settings, under the camera settings tab in your indi control panel:

  • Image:  Raw
  • Capture format:  Raw
  • Transfer format:  Native
  • Capture Target: RAM

Fyi, you might not find a ton of help with indi here on CN.  Just google search and you might find something in the indilib.org forum.
Ex:  https://indilib.org/...n-6d-setup.html

Why do you need an SD card in the camera?  Taking it out solves your problem.

Which upload mode are you using ?

 

Off their site-

 

Saving locally

You can opt to save all captured images to the local storage. This is the local storage of the device running the INDI GPhoto driver and not the SD Card. Settings for saving to SD card is also available. Under Options tab you can select the Upload mode:

    Client: Upload image to client (default).
    Local: Store image locally, never send to client.
    Both: Store image locally and send it to client as well.

That was it, thank you!

 

Despite your gloomy prognostication, I sure received a ton of help on INDI here.

 

Cheers,

I'm glad that helped!  I had the exact same issue six months ago.

 

I didn't mean for the statement about CN to be gloomy.  I use INDI a lot.  It's definitely evolving quickly and becoming much more reliable, but I still run into issues regularly and I typically find more answers in the indilib forum than on CN, mainly because the creator of Ekos directly responds all the time in the indilib forum, and it seems that only a small percentage of CNers use INDI regularly.  All I'm saying is that the indilib forum is a great resource :)
