BUG with Canon 100D on iso change and wrong pixel size

Hello,

When you change the ISO value on DSLR, and if your shoot from Ekos 3.5.2 and Stellarmate 1.5.7 the ISO value is don't change, the fits say the wrong value too.

Ex : In Ekos i create a job at ISO 400, i change the value to 1600 on DSLR to focus with liveview, i start the job, the photo is taken at 1600 ISO but the fits say 400 ISO.

If before start the job, i change the value in Ekos to other one than 400, like 800. Take a picture and change to 400 it's good.

A other thinks, the pixel size is set to 4.0 in Canon DSLR Driver but the Canon 100D pixel size is 4.3.

Best,
Franck

Hi,

I understand the you create the job with a given ISO, say 1600, and the manually change it to a different value on the machine. Since the header of a FITS image is just a hash map of texts, I’d think that the job values applies so you see that problem. Did you try to edit the job setting the correct ISO before starting it or create a new job with the correct ISO? If so: is the issue still present?
I use the same camera and never encounter this issue, but I never had the need to set different ISOs for the camera and for Ekos either.

regards

Hi,

Try take a picture at 400 ISO, change on the camera the ISO to 1600 ISO and create a new job at 400 ISO and start it.

In my case the iso value of the photo still to be the on camera settings at 1600 ISO ans the FITS say 400 ISO.

But if you change the ISO on Ekos to another value than 400 the camera change, but if you still to the same value it dont change,
i things the order change ISO to... is not send to the camera in this case.
