Home / Gallery / Astro-photography / Horsehead Nebula Mosaic 2017
Horsehead Nebula in Ha. Was originally intended to be a 9 pane mosaic, but the lack of clear skies around December 2016 and January 2017 meant that the project was unfinished for that year. The middle 3 panes had been completed (7 x 600s each) so I just combined those. Horsehead Nebula works really well in Ha, lots of interesting hydrogen clouds and formations.
