This Sh2-1 and Sh2-7 image was built by using Ha, OIII, and RGB filter.
Total exposures:
26 x 5 minutes using H-Alpha filter,
20 x 5 minutes using OIII filter.
23 x 5 minutes using R filter,
21 x 5 minutes using G filter and
28 x 5 minutes using B filter.
Color mixture details:
Ha only into the red channel!
Find the H-Alpha image (http://www.werbeagentur.org/oldwexi/gallery_deepsky/_ha_26x_starless.jpg)before mixing with RGB here:
OIII was mixed with different percentages into the green and blue channel.

You can find more images of the southern sky i have captured on my homepage (http://www.werbeagentur.org/oldwexi/gallery.html)
All image processing was done with PixInsight.
The exposure series happened in June and July during 20 different nights.
Details to the Objects:
Sh2-1: This combination of HII region and reflection nebula is ionised by the
B1V class star Pi Scorpii (HIP78265). Sh2-1 is a member of the nearby upper
Scorpius subgroup of the Sco OB2 association.
The Sco OB2 association is part of the
Gould belt (http://galaxymap.org/detail_maps/gould.html) and the inner edge of the Orion spur.
Sh 2-7: Is the core of a huge diffuse nebula and is ionised by the B0.2IVe
subgiant binary Delta Scorpii. Delta Scorpii is a member of the nearby Sco OB2
association.
Both Sh2 objects are approximatly 650 light years away.

Equipment used: Telescope T8 at i-Telescope in Siding Springs Australia (http://support.itelescope.net/support/solutions/articles/231911-telescope-%20%208) .
