Comet C/2014 Q2 Lovejoy in the west

Comet C/2014 Q2 Lovejoy is getting dimmer (50% size)
When I last looked at the comet C/2014 Q2 Lovejoy about three weeks ago, it was near its peak apparent brightness due to its proximity - it passed the closest to Earth just 3 days ago and shined at a magnitude of 4. The comet had now moved away, making its closest approach to the Sun two days before this observation. It was still relatively easy to capture it on the camera, as it's only dimmed back to magnitude 5.
The comet had moved to the constellation Andromeda. 59 Andromeda was below the comet, just outside the enlarged photo. The bright star directly above the comet in the enlarged photo is a magnitude 6.6 star called HR677 or HD 14272.
Some issues now complicate its observation other than the slow dimming. From where I observe, the western and northern sky is lit up with light pollution from the center of the city. And these days, constellation Andromeda is in the western sky, already starting to head toward the horizon after sunset. So I have to observe it in the early night, just when the area of the sky is not too brightened one way or another, at around 9 to 10 PM. The dimmest stars in this photo is around magnitude 12, so I think it was a success.
