My chosen constellation, Cassiopeia, was first named by Ptolomy, a Greek astronomer, in the second century. In theme with the crown shape of the asterism, it was named after the queen of Aethiopia from Greek mythology: Cassiopeia. According to legend, she had boasted about the beauty of both her and her daughter, Andromeda, saying that they were even more beautiful than the sea Nymphs. As punishment, the sea god, Poseidon, placed Cassiopeia in the sky - supposedly leaving her clinging to the throne she sits on while circling the North Celestial Pole.
In some of the images we took, you could see singular streaks moving across several of the images. These were most likely satellites or shooting stars that happened to be crossing the sky when we took photos. As far as things in the image I processed, the coloration of the stars in the asterism is quite interesting. Almost all of the stars are a bluish white, but the farthest star to the top right of Cassiopeia is a light yellow color. This also happens to be the brightest star in the constellation - Alpha Cassiopeia, colloquially known as Schedar.
Roll your cursor over the image to see HB's annotation and see below for her description of how she created it.
To get the results of this image, we used a Canon T7i attached to a tripod to take long exposure pictures, as well as a 50mm photo lens. When comparing individual images, there were enough slight variances that I thought it would be worth a shot to stack them. After that I used SiriL to post-process the image until I was satisfied with the look.
