Hello
For anything under a second my metadata shows the exposure time as 1/10th which is a bit disconcerting when trying to verify your data . However when making test shots at a given FSTOP/ISO i can see the images are getting darker up until the point of 1/1000th.So the software is setting the exposure correctly up until this point.

When trying to make Bias frame @1/8000 I get a bright image so unsure what value it used to expose.It was brighter than the images i made at 1/10th?!

Am i to take it then that I must make these bias frames and possible Flat frames (which will also need a sub second exposure) externally to EKOS as found another post on here where knro stated that gphoto2 had minimum exposure time of 1/000th which matches my testing.
Just odd that the capture module gives you the opportunity to create calibration frames?!
What am i missing?
