Jupiter and Saturn

I wanted to photograph the conjunction of Jupiter and Saturn. The two planets came within 0.1 degree on December 21, 2020—so close, I was unable to see the two planets as separate objects.

The photograph here was taken the following evening, December 22, when the planets were 0.2 degree apart, and still difficult for me to see as separate objects. (This was probably because Jupiter is brighter than Saturn, and its glare tended to hide the dimmer planet. Of course, my middle-aged eyes are not the sharpest.)

I actually took a photo the previous night, when the planets were the closest, but I had a much higher ISO but a narrower aperture, which resulted in a grainy image. This photo was taken with my Sony \(\alpha\)6000 camera, with a Sony G 4/18-105 lens. This was at 38mm, f/4, 0.625sec, and ISO 1000. Things are exposed to look somewhat brighter than they were to the unaided eye, but I thought this photo was nice in that it showed the trees to the left of the two planets. The last of the sky glow of dusk is visible in the photo, but it was not to the eyes. But I think this does give a good sense as to what the conjunction looked like to the eyes.
