For me it's only binning.
I actually do use 2x2 for focusing and plate solving.

We are still trying to find the reason what causes this binning problem. Currently, only binning has been reported to be incorrect.

Do you have logs and both scheduler and capture sequence file to share?

Wolfgang,
The log is in my first post.
Attaching the sequences.

Max, your scheduler file references E:/_Astro_in/Targets/5x360-ASI2600.esq, not the 15x120 file you posted in your zip file. I guess there is nothing surprising in it, but please post it as well.

Oops... Sorry. Attaching

Installed INDI 2.0.4. The Scheduler behaves well in terms of binning now.
Ran everything on Mele Stellarmate X. No Windows client was involved.
Will try Windows client as soon as it's available.

Installed official KStars 3.6.7 Stable for Windows released on October 4.
It's still doing bin 2x2 thing when using Scheduler!

-- this doesn't happen when everything is run on Mele Stellarmate X
-- this only happens when the client is Window KStars
-- this doesn't happen if I take a 1x1 picture in the CCD/Acquire module before starting a schedule in the Scheduler
-- if I "manually" goto the target, plate solve, focus, check the guiding and then start the Scheduler - then this happens.

???

I was hit with this bug yesterday as well. I will investigate it deeply today.

Oh... Great!
I mean - bummer : (

I also have a strange problem with BIN 2,3,4 They remove all color information and geometrically stretch the subs horizontally! My release is latest, My DSLR is Sony a7 using Sony DSLR as driver and a5000 using generic gphoto. (Stellarmate 1.8.1 OS)
