Thank you very, very much Jasem!
I have an Atik One with an internal filter wheel and the GP guider, I got two issues (I am not on the nightly channel):
- I can not change the name of the filters [ERROR] Error updating names of filters.
- GP is not visible (normaly connected via internal Atik one Hub, an SX Ultra can connect via the hub)

Hope this can help

captured an image of 300 seconds

Jurgen,
We use the same camera, do you also remark a difference in the image size between v1 and v2 driver?
For me with v1 the maximum frame size was 1392x1040, now with v2 it is 1391x1039. With v2 this is now the same size as given by Artemis capture or the Ascom driver on Windows.
Not a big problem but in this case you must be careful to redo your calibration frame with v2.

yes, I've noticed it too:
it is 1391x1039 now, but it is not a deviation from the previous versions of Ekos and or Indilib. I have dark images captured by Ekos from 2014 that have the same 1391x1039 frame size. I had problems with the frame size being 1392x1040 when I captured flats using APT.

On 383L+ the frame size changed as well to match what Windows tools give, 3326x2504 to 3362x2537 so had to redo calibration frames. There are a couple of rough edges, temperature reading seems to interfere with image download but adding a mutex there fixed it. Another thing is that subframing is not enabled on my camera as the driver is checking for a capability which presumably means something else, but enabling the capability unconditionally fixed this too.

A PR is appreciated!

Mine is 383L+ too.
I've notice the same behavior with sub-framing not allowed while testing auto-focus.
I believe that donwload time get slower too, but maybe it's only a "felling", I don't have numbers to compare.

Subframe work with the 314L.

I compare the time need to take a bias with a previous session log and it is not slower. From old log 4.6 s, from new log 4.5 s. This is total time from start of exposure until the file is saved by the client.

Ok so subframing issue is confirmed. There is "preview" mode which I didn't enable. At any rate, if the camera supports preview mode, then it would be faster, but Ekos has no idea about this and it must be set from INDI control panel before you start focusing..etc.

I tested the last change with the mutex. It work fine, no problem with my camera.

Good, I noticed the issue when taking new calibration frames, around every 8-10th frame would time out downloading. 383L+ has larger frames so it takes longer and the window for race condition is thus much larger. But with the fix I got the calibration frames all taken and imaged a couple of nights without problems.

Some inteface tests.

When first open focuser tab with Atik, the subframe is disabled "but" with a check-mark (I think this check is disconsidered when disabled, but I don't know). Then I selected the guider camera, that enable the box. It comes "selected", I unselect and switch back to Atik. Then Atik show the box disabled but unselected.



I didn't find the "preview" mode that need to be set in INDI Control Panel. It should be there?



The last picture is from Ekos, nothing to set there too.



I think that you are talking about an "internal" set that need to be checked on driver, not on visual interface (maybe I misunderstood).
I saw people talking about "mutex", is it something that I can "configure" ou it's a code change?
And the last thing, Jpaana says that 383L+ shows frame size as 3362x2537, in my case, same camera, 3354x2529 (firmware 801).

Thanks
Mastria.
