2018-09-07 Trifid Nebula (M20)

Early september I could add 2 new little sessions to my previous windy try at this subject.
Now stars have a much better shape.

Still needs more subs to allow for more stretching and uncover more clearly the blue nebulosity around the main, red part.

Capture: blend of 9 x 30s 3200 ISO on Celestron Nexstar SLT tracking Alt-Az
+ 13 x 40s 1600 ISO + 10 x 30s + 4 x 40s 3200 ISO on Omegon EQ-300 tracking RA
(total exposure: a bit less than 21mn)
