Horsehead panorama
Alnitak, the eastern belt star of Orion is flanked by the Flame Nebula and the silhouette of the Horsehead Nebula.
The picture is from an imaging run in Summerland on the 0° night of February 17, 2015. A total of 16 ten minute exposures were taken with a modified Canon XSi DSLR camera through a Borg 101ED apo in f4.2 astrograph mode using an IDAS nebula filter, and they were processed and combined in ImagesPlus.
