Btw, I can control the shutter cable in ASIAIR Pro via GPIO#21. So, I can control any unsupported camera via the bulb cable. Let me know if you want to add the feature, I can help test the feature.
Shutter on
<code>import time
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(21, GPIO.OUT)
p = GPIO.output(21,True)</code>
Shutter off
<code>import time
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(21, GPIO.OUT)
p = GPIO.output(21, False)</code>
I've added shutter control in my Fork at github.com/ken-self/indi-3rdparty.git

You'll need to build from source as it is not yet ready for pushing to the nightly builds. Some refinement needed but the basic operation looks ok. I can only test by attaching a LED to the relevant GPIO pin.
It needs some work at the shorter exposures and exposures with decimal places.
I confirm that the configuration file and the DSLR shutter control work well. I tried it with my Olympus camera. See the attached photos. Thanks a lot.
I've just pushed through some changes. I've made the DSLR timing a lot better (around 1ms for even long exposures) , fixed some edge conditions, tidied up the messages and set more sensible defaults. They should appear in due course in the nightly builds. Let me know of any improvement requests.
Out of interest, do you use the DSLR standalone and capture the images on its memory card or is it connected to Ekos with USB cable for image transfer?
I'm wondering if it is possible to integrate with the camera driver somehow e.g. by snooping.
