It’s been over two years since I (or most people) have attended a public star party. In June I returned to one of my newer annual favorites, the Grand Canyon Star Party. I’ve attended both North and South Rim events, but this year I spent at a week at the south rim event doing public outreach each night, and sneaking in some astrophotography on the side. Conditions for deep sky work here are not optimal because of the lunar phase (the Moon comes up not long after midnight), but it is a glorious opportunity for nightscape work.
My Sigma 20mm f/1.4 performed as well as always, but I tried a new lens this year, the Tamron 35mm f/1.4. I was amazed by its performance. Not only was it sharp and fast, but even wide open, it was dramatically better than the Sigma lens at the same f-stop. I took some snapshots with it, but it really performed on a tracking platform (I used a Sky Watcher Star Adventurer AZ-GTI) with a 20 second exposure. I actually meant to do a full 30 seconds (the maximum exposure without an intervalometer on my Canon EOS Ra), but my fat fingers, the cold, and distracting wind… well, I got what I got! Tell me, does it not look like a giant crab monster in the sky? Or is it just me.
