Ok thanks for the help but I am going to abandon my Indi project till next year. I need to be able to trust whats going on and DSLR on Indi with my Canon 100d is playing ball. Good luck with your project - clear skies
One question do you use LAN or Wifi for your connections - I use Wifi (connected by Realvnc)?
Something else I have noticed since 2.5 now getting double click of lens shutter and or Mirror Lock - but they arn't he correct number of seconds - e.g. 2 secs mirror lock last click noise maybe 5-10secs after image is displayed.
Also black images are starting to appear if you change ISO settings or exposure length.
I have ( i think) found the problem, I know I was going to ignore it until next year but the weather has been bad for Astro so I did some more testing/digging.
The problem appears to be Noise Reduction setting in my Canon 100d - I have it on and my APT works no problem however this causes no end of weird things in Indi/Ekos which I believe is a timing problem caused by NR.
If I switch NR off on the camera Indi / Ekos works for both FITS and Native no matter what expo time I set (well 60 ,30,20,10,6 secs all work ! )
