The TravelerComet (C/2020 F3) (NEOWISE), over Butte, Montana, July 14, 2020. July 2020 seemed occupied by tracking and photographing Comet Neowise as it swung by the earth and sun. In defiance of fears that it would disintegrate, the comet came from behind the sun and became visible to our eyes.
I ended up taking a lot of photos (trust me, you will never see most of them) and in the process learned more about how to capture images of celestial objects, while preserving smooth, blue, night-sky gradients.
It seems to be troublesome:
To create this image, I aligned five images (each taken at ISO 3200, f5.6, and 4 seconds) to sharpen the comet and control sensor noise. Keeping the sky smooth was difficult, because that part of the image was still short on the information needed to produce its colors. Increasing the ISO and/or lengthening the exposure would likely have helped.
I like this image because I managed most of the exposure issues and captured some detail in the comet's tail. However, the endmost parts of the tail likely extend off the image to the right. I wish I had moved the comet a little to the left and down so that it didn't crowd the right side.
On the bright side, I have lots of time to learn more about night sky photography; Neowise is not scheduled to return for about 7,000 years. I might have it down by then.
