C/2020 F3 NEOWISE So Near The Horizon July 18, 2020

I reached the site too late for imaging at the night after flight from Tokyo and driving from Asahikawa. The comet looked big together with the long tail at the dark site with my unaided eyes. WOW!

 

It was unfortunate that my equipment was troublesome at the night. The portable Li-ion battery FLOUREON 12v was not enough for the system. The object was behind the woods, when I started imaging.

 

The object came out from behind the woods after the beginning of twilight. The height was low, about 4 degrees from the horizon at the beginning of the imaging session.
