Started to learn a little more about how to do Galaxy processing. It is a totally different animal. Control the star size is such a headache. There must be something that I don't know yet - there is no way I could bring out the blueish dust glows and the vivid color of the core. I like the natural-looking result with good details. But I also like to know how to "pop" galaxy colors. Next time.

Huge thanks to my teammates TBC George, Chen Wu, and Yizhou Zhang for helping me complete the data acquisition. The weather at the beginning of 2021 was truly horrible!
