Comet C/2025 A6 Lemmon from the Eastern Sierra - What a tail!

On 10/17/2025 05:00 am by Jeremy Evans | Website | Eastern Sierra, CA , USA

I've been tracking Comet C/2025 Lemmon for most of the month, as of October 17th it was pretty low on the horizon a few hours before sunrise. On the morning of Oct. 17th the moon was a waning crescent at only 12% illumination so it didn't wash out the comet. Single capture under Bortle 2 dark skies from my backyard.

On the same night I was observing Comet_C/2025 R2 SWAN just after sunset.

I started photographing comets when I was 17 years old in 1996 with Comet Hyakutake, this was the first time in over 30 years I was able to see two comets in one night! Amazing!!!

TeleView NP101is APO Refractor, Losmandy EQ Mount. 3 min exposure, single capture.
0.8x focal reducer so I can fit the long tail

Slight NR and had to remove a few Starlink trails.
