i think that a good solution that does not introduce side effects will imply changes in both gphoto and indi. It should be well tested before pubblishing it. As You suggest, Canon EOSs do not always behave in the same way. I have only 450D to invent and test solutions and this is not sufficient to declare a general fix. I might study the code but I am sure that inside Indi community many guys know the code better than I do and everything would go faster with his help.

Anyone reading this post that takes the chance ?? :-) ....

Hi alfredo, knro
I'm just an amateur astronomer so the programming/source code is way beyond me, but i'm happy to support with testing.

From the gphoto forum Marcus confirmed a basic single shot command line sequence that did work on my 60da which I copy below:-

The final is not "Off" but try "Release Full" or "None".

The BulbExposureTime should not be incrementing anymore and the image should
be downloaded. :)

Hi !!!,
testing is always welcome and Your camera is well known in the astrophotography world.
I just read of indi version 1.0.0 released including some improvements about problems I encountered with indi. Well done ...

Just a note :
my EOS 450D consumes a lot of power while connected by USB, I guess the same applies to 60D, so ... pay attention.
I use a dummy Canon battery (sold by Canon for EOS 450D) that plugs into 220V, so there is no need to recharge original batteries.

I did not yet take many many astro pictures, but since I have been using it, this dummy battery has been saving me a lot of time, especially under cold temperature conditions.
