Description

R = 1215 x 0,24 sec und 1488 x 0,35 sec und (Version B, C) 434 x 0,75 sec

G = 1598 x 0,20 sec

B = 1609 x 0,20 sec

This was the second attempt on 19 March 2018 to image the trapeze with short exposure times. Close to the brightest star in the trapezium (C), the component F is just visible. Also H1 and H2 are weakly recognizable. The stacking was done with the drizzle-function.

The luminance is taken from the red channel. In Version B are added 434 x 0,75 sec captured on 4 March 2018.

In Version C some objects are marked.
