Morning all,
(Posting on here during a quiet moment at work. Just don't tell the boss!)
I think I have all the questions answered - yell if I've missed anything obvious...
I run Kstars/Ekos on a Linux laptop (Kubuntu 22.04) and get all the Ekos software updates directly from Jasem's package repository. (Instructions taken from the various pages over on Indilib.org.) All the hardware is connected to the laptop via a powered USB3 hub.
When I get a chance I will see what bit-depth Ekos is using for the camera. I suspect it's 16-bit, rather than the camera's default 12-bit, and the higher 4 bits are being padded with zero. Then I can work on finding a suitable ADU value.
The light box was made by Peter Miller and fits neatly over the end of the scope. The dimmer controller takes it from really bright all the way down to really dim, so no problems with finding a suitable brightness.
When taking the flats I aim for a minimum 3-second exposure and adjust the brightness of the light source to suit. I think now it's a matter of spending the time to find the correct brightness of the light box to generate a good flat.
The question I do have at the moment - when looking at the flats (in Ekos' FITS viewer, 'Tenmon', or through 'QuickFITS' on my desktop) do I stretch them?
Cheers,
V
