Apologies if this is a very noob question. I am an experienced event, travel and sports photographer but quite new to astro.
I am unsure which lens I should reach for first when there is a clear night sky. I have an 85mm f1.8s, 70-200 f2.8s and a 200-500 f5.6. I don't currently have a tracker.
Am I better off with a lighter faster lens that requires more cropping (85), a larger slower lens with less cropping (200-500), or the lens in between (70-200)?
Orion Nebula, Rho Ophiuchi Cloud Complex, Pleiades and Helix Nebula are currently on my to-do list. I live in Auckland, New Zealand so I have picked southern hemisphere targets. Although I am open to suggestions as well.
