Flying Horse Nebula - NGC 7380
NGC 7380 is a young cluster of bright type O and B stars near the center of this image.  The red emission nebula Sh2-142 is part a large HII region illuminated by these stars.  Interspersed dust lanes shape the contours of the nebula into a flying horse, trailing a long flowing cape. 

This image combined 320 minutes of H-alpha, 130 minutes of red, 80 minutes green and 100 minutes of blue exposures, all unbinned.  Total exposure time was 10.5 hours.  An ST2000XM camera was used through a TEC 140mm refractor.
