Comet Lovejoy and the Pleiades
Comet Lovejoy – Change in Position in One Day
Sunday and Monday evening it was clear, so it was time to find Comet Lovejoy again. This time it was near the beautiful Pleiades. Of course, that is worth a picture.
I thought it would also be fun to see how much the comet had moved over one day – the change is quite visible. I was hoping to go for a three-day comparison, but now it’s cloudy again.
Camera geek info:
- Canon EOS 60D in manual mode set at f/4.0, 3.2 second exposure, ISO 6400
- Canon EF 70 – 200 mm f/4L lens, set at 94 mm for Pleiades and comet and 200 mm for comet, manual focus at infinity
- Cable release
In choosing which picture is the best, I find that I am using the following criteria: good focus (automatic toss for out of focus picture unless happen upon cool “artistic” effect), no visible star trails (stars should look like a point, not a line), visibility of comet, color of objects, color of sky, and noise of sky. While I have pictures with darker, less noisy sky, they don’t show the comet as well.
I am also finding that the image quality is far better when I zoom to my desired field of view instead of cropping in post-processing to get there.
