Hey hey, still me... slowly getting the hang of it - but still very new to both astronomy and photography.
I am trying to understand what's the best way to put my DSLR camera (Canon EOS 2000D) into focus. At the moment I am using the telescope focus during the initial alignment to make sure the brightest stars I am using to align the telescope are in focus. Then, once Ekos is up and running I am trying the autofocus, but it keeps failing (saying it was unable to select a star automatically). In the Camera tab, if I take a pic with the same settings used for the focus (25", ISO1600), I can actually see a handful of bright stars - although slightly out of focus.
How do you make sure that the camera is focussing your target correctly?
To eliminate any issues due to starting focus point, you should start you first autofocus sequence with your best focus point (if you have a bahtinov mask use it to focus your system). Check your mechanics settings : initial step size and out step multiple to be sure that the first capture always show a few stars identified by the search star algorithm. To do that, after a good manual focus, move your focuser using (initial step * out step multiple) and take an image to verify star size and star detectivity.
What telescope are you using, what focuser do you have, or are you using a camera lens? Without knowing your setup, it is impossible to give meaningful advice.
