C/2022 E3 (ZTF) 2023-Apr-12 Dan Bartlett

No longer any hint of "green" as the now - faint 11.5 magnitude comet C/2022 E3 ZTF has closed in on my western Horizon. Yep, lots of artifacts from the conifers in this stack of 13 x 45 seconds (actually at no time was any of frames -the entire 3.2 x 2.1 degree field -free of trees). Most of the images were taken when the comet was less than 15 degrees up, in a gap between my mountainous horizon.

That's my excuse for these!
