That should get you on the right track. Also recommend that you get
four apps for your phone:
* PhotoPills (https://www.photopills.com/) Once you have it loaded,
go to the "Spot Stars" icon. You'll find a very handy NPF Rule
calculator that you will need to customize for your camera and lens.
* The Photographer's Ephemeris (https://www.photoephemeris.com/)
* Stellarium Plus
(https://www.stellarium-labs.com/stellarium-mobile-plus/) This is
the only sky view app that shows where to look for NEOWISE.
* SkyView (https://skyview-free.en.uptodown.com/android)

Greetings,
Firstly - this has nothing to do with darktable. My apologies for
being off topic. From my point of view, there are lot of experts here
who can help to improve photo quality. If you think it's
inappropriate, please feel free to delete.
Comet NEOWISE is going to be visible for next few days. I have been
seeing some stunning photos, some of them on mobile phones. I'm that
person who is often wrong in camera settings and trying to learn from
internet resources. I don't have fancy camera or lenses, but my hopes
were raised after seeing mobile photos from Samsung devices. I should
also mention, after spending a year just to be safe, I have finally
stopped shooting jpeg+raw to just raw as photos seem to be more
recognizable these days and my knowledge of darkatable and post
processing is increasing.
Are there any tips experts willing to share for taking picture of
comet. I have a tripod and and assumption that weather will
cooperate. I know about and aperture and shutter priority modes, but
do often get confused which one to use. As most of the videos and
sites say, I'll be using aperture priority.
Thanks in advance.
Niranjan
