M20 Trifid, M8 Lagoon, NGC 6559 Chinese Dragon and everything nearby

Accumulation over all clear nights of the first two weeks of September. The accumulation turned out so-so. Out of 500+ 2-minute frames (gain -25 at 0 degrees), only 85 were usable. Efficiency like that of the notorious steam locomotive... These objects were hanging low above the horizon, conditions were so-so. Stray light, gradients, planes in crowds. 1/3 of the frame around the edges had to be cropped. The question arises - maybe it would have been better to shoot all this with a 200mm focal length right away? At 135mm it's some kind of neither-fish-nor-fowl: no longer a landscape, but not yet deep sky.
