Demonstration how to measure the magnitude of comet C/2019 Y4 with ASTAP

[han59]

I have made 5 minute video demonstrating how to measure the magnitude of comet C/2019 Y4 (Atlas). It's an almost fully automated process. The comet flux is measured and converted to a magnitude using the imaged stars as reference. Calculating the star magnitude/flux relation is fully automatic using Gaia DR2 catalogue as reference (calculated Johnson-V). The only manual operation is selecting the area and removing the stars near the comet.

Feedback about this new method is appreciated
