Bottom-left: Spaghetti nebula (Simeis 147).
Upper-right: Flaming Star nebula (IC 405).
The big, blue star between them is β Tau (Alnath).
This image is a crop from a larger mosaic, which I created with data acquired over the years. That makes it difficult to say how much data is in here. Definitely over 30 hours total, likely more, using HaLRGB filters.
This was the first whole night I went nightscaping in 2020. I mostly stayed along Tioga Rd, which was, as expected, without a soul (saw four cars pass in the whole night, that's all). This is an easy stop near the top of the pass, but still a gorgeous view, as it happens almost anywhere in Yosemite. The airglow was strong, not a cloud in the sky and not too cold temps (about 45F). Couldn't ask for more!
