Hi Euripides, yes that's correct. When creating a set of Flat jobs in the Camera tab, click on "Calibration". In the flat duration use the ADU and set the desired ADU (I use 25000). Then set the exposures for each flat to 1sec and take the flats. It will take a series of test exposures until it gets
the correct one (according to your ADU) and then it commences taking the Flats at this new exposure. Note once all the exposures have been
been done the exact exposure time can then be seen in the Exposure box. If you want to then create DarkFlat just double click on each sequence
and change "Light" to "Dark" and click the tick box in sequence queue. You will then have a Dark sequence using the exact same exposure as the light.
This is useful if you have a set of filters to go through.
Yes just proceed as if you have a 16 bit camera. It is just a constant scaling so the ADU setting can be the same for any camera (12, 14, 16 bit) all
treated the same by indi.
I use 25000 which is 38% of 2^16 . I think 25-50% is often quoted.
If you run your mouse over an image in FITS viewer, in the bottom right corner you will also see the coordinate (pixels) and value (0-2^16-1).
Also in FITS viewer click the "Statistics" button (3 bars looks like a histogram) and it will show you min, max, mean and median values of the image.
Hi Jasem. Just tested the new DarkFlat feature. I like it. Take the flats then press "Generate DakrFlats" button to get a new set of jobs.
Ok there is bug. When I take the flats it doesn't update the frame counter so I just end up with 1 Flat for each filter. DarKflats ae fine.
I just updated to 3.5.7 stable. I got 1 frame in each case for 2 filters. DarkFlats fine. I'll reboot and retry.
