For whatever reason I can't do that. In INDI/Canon DSLR/Options there is a switch called Debug but once I click at Enable it is immediately reset to Disable. How can I change that?

Ok, never mind, got it. Logging must be enabled first in order to have that button functional.

One last comment... the exposure value changes to 0,010 by itself after taking the 0,001s photo, indeed. However, it does not change from 0,500 to 0,050 as I had said. My fault.

So from the log file you problem is here:

shutterspeed has only one member (bulb), where in my case (Canon 600D), it also lists all the exposure values down to 1/4000. I'm not sure why this is case for your? Maybe you need to change the dial position on the camera? I put mine to manual and then select blob in the menu.

At any rate, I added another check so that if there is only one option in shutterspeed then it falls back to bulb in case for short exposures as well. The updated build should be available tomorrow.

I see. With the 5D Mk2 there is no "bulb" within manual mode. It's just 1/8000s up to 30s. Bulb is a separate dial position. I'm looking forward to testing the new build.

Hmmm. Can you test again with manual mode and attach the log? I'm curious to see if it returns shutterspeed list

You genious! This makes quite a difference. It does 0,000125s shots now. The next stop is 0,010000s. There are quite a few missing in between but other than that the whole thing does work correctly now, at least at first sight. I'll check it out in greater detail...

Great! The only downside to this is that it is limited to 30 seconds (Manual Mode). So if you want 30+, you have to switch to Bulb mode. But if you change from Manual <--> Bulb, you must disconnect/reconnect the driver. At any rate, I think you can live with that.

I tested photos at all exposure times available in the GUI. All off them appear to be exposed correctly! For very short exposures the file name isn't long enough.
