Description

Despite 1st quarter moonlight, I was successful in capturing Comet Lovejoy on 28 Jan. The original image has minimal processing. Version "B" is enhanced using Photoshop. Version "C" compares the comet on the 27th and 28th. The increased moon lit background is noted on the 28th (right).

The final shows from left to right cover clear skies between Jan 10 and Dec 19. I attempted to provide minimal post-processing, calibrating histogram with the same RBG balance and L (approximately).

It is interesting to note how this comet changes dramatically every day.

Taken at f/3.5. This comet is now moving very quickly. Motion is noticeable in less than 5 minutes (5.5x normal naked eye magnification).
