Ok, I asked Robert to look at this since it appears to be some Mac issue?

Not quite sure what did it but now I have a log file.

If I set the camera to Av then connect it I do see the shutter speed being parsed:

....

But if I try to set the shutter speed to 0,00025 then I cannot enter the "25". After 3 nulls the UI refuses to accept anymore input.
I do live in a region where the decimal character is a ",' and not a "."
I have of course tried both.

Jasem, I think this is related to another issue that we had been discussing a while back. Although my EOS does list all shutter speeds from 30s to 1/8000s,

I can choose just a few of them in Ekos.

0,000125
0.01
0.02
0.05
0.1
0.2
0.25
0.5
1.0 and up are available. All shutter speeds between 1/6000 and 1/100 remain unavailable.



This appears to be independent from the number of digits since 0,000125 is OK! Back at the time I was happy to take planetary pictures and didn't mind the missing shutter speeds. Just recently I started using my 5D again and realized I was unable to take decent flat frames without these.

Hello Alfred, the numbers you see there are just the suggested number by KStars. You can put any number you want in there yourself.

You're right, thanks for pointing this out. I tested 0.001 and it does work correctly. However, this means something must have gone wrong when I tried to take flat frames. I'll try to replicate and report back. Thanks again!

OK, the problem is the cam will take pictures using the shutter speed that is selected in the camera menu, not the one chosen in Ekos. If i set the camera's main dial to manual mode (as I should in order to have all the shutter speeds listed and available) and the "sub-dial" to 1s (or any other value), the picture that is being taken will be using the shutter speed that is chosen in the cam's sub-menu regardless of the shutter speed selected in Ekos.

The logfile is from taking two exposures, one at 1 sec (Ekos setting) and the other one at 0.01 sec. In fact both are 0.5s exposures and look 100% the same. Force Bulb "ON" and "OFF" yield the same results.

During my test I noticed "Force BULB" is not being saved when clicking Options -> Save in Indi Panel. It always sometimes comes up as "ON". Can't reproduce it anymore.

Ok, this is odd:

1) Set "Force BULB" to "OFF", Save Options, shut KStars down, start KStars, start Ekos, "Force BULB" is still "OFF".

2) Set "Force BULB" to "OFF", Save Options, shut KStars down, switch the 5D Mk2's dial from "Bulb" to "Manual", start KStars, start Ekos, "Force BULB" is now "ON".

I believe many issues we've experienced stem from the fact that there are two distinct groups of Canon DSLRs: One with a separate "B" dial setting (like my 5D Mk2) and the other group were "B" is one among many shutter speeds within the "M" dial setting (like Jasem's 600D). It appears to me these two groups behave differently and this is what causes trouble here.

Rishigarrod's 6D has a separate "B" dial position for bulb mode just like the 5D. When I select "B" on my 5D, I run into the same problem that he described. The "Exposure:" field allows no more than 3 digits after the comma.

This could be intended since such short exposures can not be reliably timed in "B" mode. Setting the dial to "M" doesn't help since the camera then dismisses the Ekos Exposure: setting altogether.

So the workaround is set the Camera to M and select the correct speed on the camera. The settings in Ekos will then be ignored?

Should we develop a second driver or do you think we could modify the driver to take the actual model of camera into account?
I am happy to help with any coding.

Under normal circumstances this would work, yes. But not so with taking flat frames which is an automated procedure during which Ekos changes the shutter speed in order to approach the target ADU.

I'm unsure whether this is necessary. Re-reading This message suggests the driver once DID work correctly in "M" mode for my 5D. I am surprised to see it does not work anymore. I haven't used my 5D since then (more than a year) so something might have been changed in the code in the meantime, something that is responsible for the change. Let's find out whether this is the case first. No matter what, I am willing to devote as much time as needed to get this sorted. Jasem had been working on this in the past and probably knows what's going wrong already.

Since you know how to code you're probably familiar with GitHub. At least more than I am. Anyway, github.com/KDE/kstars/commits/master lists all the changes that have been made to the code. The relevant code probably lives in indi/3rdparty/indi-gphoto/ I don't know how to list the changes in the relevant part of the code only. If you know how to do it, please let me know.
