Flaming Star (1500ly) and Tadpole (12,200ly) Nebulae in Auriga

Over the last 3 nights in competition with the clouds I still managed to get 109 quality pics. I had to chuck 42. These two nebulae are both so interesting in my opinion that I had to image them together. That required me to use the 384mm version of my telescope (that also decreases the f stop from 7.5 to 4.8). For some reason they seem to present themselves more appealingly in a vertical manner to me.
If you look carefully (zoom in) on the lower Tadpole Nebula and look to the left of center you should see tow bright stars (white dots) and to the left if you look even more carefully you will see their bodies as they swim towards the center.
Space is just plain interesting to me. To infinity and beyond as Buzz would say.
ASI2600MC Pro g100, AskarV@384f4.8, 109 10min pics (18.7 hours) exposure, +darks/biases/flats
AM5/ASIair+, EAF, Askar OAG with ASI174mini for guiding
PixInsight 100%. This turned out to be a rather challenging process because I basically processed the entire project twice. There a lot of technical reasons for this and it turned out to be wise. The first run had too much blue because of high clouds. The second time I ran I removed 42 more questionable images and it ended up substantially improving the result. Sometimes more is not better.
Because I took so many pics and had a bit faster f stop I was
able to bring the Ha out in the pic to the brilliant red that resulted.
