save last measure of camera rotation and load when starting the profile.

[deneb Cygnus]

Good evening.
Every day that I use your great software, I have to perform a set camera rotation.
Is there a possibility that every time I press "determine camera rotation" the angle is saved, so I don't have to take a shot every time I start the software?
I don't know if it would be interesting if it also happens with astrometry.
Greetings and thanks.

Determining camera rotation through a plate solve is a source of truth, though. What happens if the orientation changes for some reason - reconfiguring of gear, slippage (however minor), or other mechanical movement? Whatever NINA would have saved for the last-known rotation would be an assumption that is not verified.

That's right Dale
Maybe I don't express myself well,
The idea is, you press the "camera rotation measurement" button, it performs astrometry and saves the measurement and when you start the program, you don't have to perform the same task.
Another option would be, every time you perform an astrometry change the value, so ask if this part would be correct.
the first one in my case is perfect.

Hi,

what Dale was saying is that in the time the application is closed and then restarted the physical rotation of the camera could be changed. This is the case for almost all non stationary setups and on application start it is unknown to N.I.N.A. what the true sky rotation is so it requires you to do the solving.

Hello Stefan,
Yes, I understand!
In the event that the equipment is mobile, you will always have to take the measurement, but for those of us who have static equipment, it helps us to have the last measurement saved.
Also if you have a rotator, the position is not fixed,
but in a statistical table, you solve for one of the three options, which is more than none of the three .
It is not a problem either to have to take a measurement when starting the session to find the frame, but in my case it is much more comfortable that it is a variable saved on disk.
Grateful for your help.
