Description:
This is the nebulous region around Alniyat, in the constellation Scorpius. The wide field image includes a hydrogen emissions nebula and two globular clusters, M4 and NGC6144. In the wide field image I combined almost 9 hours of exposures with the 8” and 80 mm telescopes, using two different filters.
