This and the previous image are different stacks of the same 5 exposures. This one was done by Sequator (fully automated alignment, only needed to draw a rough sky region), with 15 dark frames. The stacking also greatly reduced noise in this case. The improvement from using dark frames was obvious as well. The “reduce light pollution” function with the “uneven” option worked really well. While it did not remove light pollution completely, it darkened the sky by a lot which made the Milky Way more prominent. In addition, Sequator handled (“froze”) the foreground in the same process. The noise seen in the image was due to the use of the “Auto brightness” function. It was used in addition to the HDR option (against the software author's suggestion) simply because it made the Milky Way even more obvious, though at the cost of bringing out much more noise. Nik Define2 with luminosity mask reduced it somewhat. Another issue with the AB + HDR approach is the colors of the result look a bit unnatural and very different from the Photoshop result. I was not able to adjust the colors to be close to image 1.
