10 Minutes on Comet C/2023 P1 Nishimura, Captured 2023-08-18

Wishful thinking, I know, in this cometary pursuit we all crave. Still quite low to the mountainous horizon at twilight entering the scene.  This image is a stack of 30 x 20 seconds centered at o5:oo.  Tomorrow a possible road-trip for a lower horizon equaling more time on target...hooray.
