Description

High clouds moved in only after taking 9 subs. I was very lucky to capture Lovejoy tonight. Moonlight becoming increasingly bright. I was barely able to see the comet naked eye while overhead.

The original image was not post-processed except for PixInsight star alignment and integration.

Taken at f/5 at ~6:45PM MST. Lovejoy's brightness is slightly less that 39ARI or +4.6 magnitude based on my estimate.
