Description

Despite a pretty thin crescent moon, capturing Lovejoy is becoming more problematic. Tonight, I took longer subs at lower iso and the result was surprisingly good.

Taken at f/5 at 7:25PM. I was still able to see the coma of Lovejoy naked eye despite the moonlight. I'd estimate Lovejoy's brightness equal to 39ARI = +4.5 tonight.
