Title Rho Ophiuchi and the Blue Horsehead
Description First astro attempt with my K1 Mkii. I kept the ISO to 1600 and exposures to 60sec and got a good number of light frames (70) and then stacked the best 81% in Affinity photo along with 9 dark frames. To process I used Affinity Photo, ACDsee for color saturation, Astroflat Pro (plugin), and starnet++ (very handy freeware)

Oops. Those were 67second exposures. Lens was left wide open at F3.5
