Nigel,

Quite happy to learn something if I am wrong.

There are some cameras out there with larger than 64K and I am pretty sure they still display only 64K levels.

Nigel,

It may be decoded using 14bit but that does not equate to an actual brightness level only to the number of differentiated levels.
The 14bit (16,384 levels) values are returned as 16bit (65,536 levels) values so each level will be equal to 4 when shown.
This means you should think in terms of 65,536 when setting a flats level.

Nigel,

The trouble with taking sky flats is the light is always changing, which makes it a problem if you want to subtract darks.

I have even found this with a light source, but it is generally more consistent.

My suggestion is to move from sky flats to a flat light source.

Peter,

Thanks, I missed that point because the Ekos libraries did not build correctly at first, due to missing packages.

I thought I had gone back and rebuilt Kstars but it must have been before I resolved the Okos issues.

It is now working.

Yes, I compiled it from source, which is something I have done maybe 50 or more times over the last 5 or so years.
As mentioned indi-sx is not building properly but everything else appears to be; if you ignore all the usual warning messages that the compiler gives.

I have checked the Settings/Configure Toolbar/ menu and the first three were selected, but the Telescope Toolbar wasn't.
I selected it and restarted Kstars but still no Ekos menu.

I have just performed a complete build of stellarsolver, kstars, indi and indi-3rd party, on Raspberry Pi OS Buster 64bit.

This was a complete rebuild of the OS as well.

There was an issue with make of indi-sx but everything else appeared to complete successfully.

The problem is I cannot access Ekos.

What can cause this issue?

John,

I don't think it works on Bullseye, i have been unable to get it working.

Vladimir,

You and ASTAP have made my day :)

I could not find that in the manual but it is a fantastic feature.

Vladimir,

ASTAP is one of my favourite programs but I wasn't aware that it could edit the header for individual files let alone as a batch.

How do you do it?

Now that this has been addressed can someone suggest a Mac or Unix program that can bulk edit the existing FITS header to add an object name.

If you have a QSI camera working to take a series of images running Raspberry Pi OS Bullseye 64bit, please let me know, otherwise, I will raise this as an issue.
