Advice please. I have an opportunity to spend a couple of nights in Portal, AZ whiich is a Bortle 1 dark site during new moon. I plan to do some milky Way photography. Here is what I have. Canon Rebel T7, Canon 24mm F2.8 lens, Ioptron Sky Tracker and intervalometer. I have a small budget for an additional lens. Would appreciete guidance on the suitabilty of the following, and if you think they would be an advantage over the Canon 24mm bearing in mind that this is a crop sensor and 24mm really means 38mm...
Rokinon 14mm f/2.8 IF ED UMC Lens, Rokinon 10mm f/2.8 ED AS NCS CS Lens, Canon EF-S 10-18 f4.5-5.6 IS
Also appreciate any other thoughts in the under $500 ish price range.
