M33 - The Triangulum Galaxy
Photo description / processing
The first session took place on November 2nd, and I only managed to capture through the red and blue filters. I completed the green channel only on December 26th. After finishing the post-processing, I noticed an "artifact" in the upper right corner of the frame in the form of a sequence of red and blue dots. At first, I wanted to remove it, but after an investigation, it turned out to be a large Jupiter trojan asteroid from the Trojan group - 16070 Charops, with a diameter of over 60 km. At the time of imaging, it had an apparent magnitude of approximately 16.85 and was barely distinguishable in individual frames. The color is explained by the use of a monochrome sensor, and the absence of green dots is because the green channel was completed almost 2 months later. So, a small thing - but a pleasant one.
