Welcome to steemit! I am also a photographer and love astrophotography, although I don't do as much of it as I would like. What lens is your favorite for the night sky? Do you do stacking? What would you tell someone who wants to do astrophotography for the first time?
Definitely the Rokinon 24mm f/1.4. Just gotta make sure you get a good copy of the lens since they're known for quality control issues.
I don't do any stacking.
Don't let your equipment stop you. I shot milky way photos for my first year with a kit lens and a Nikon D5100.
