SH-101 (Tulip nebula)

SH-101 is a faint emission nebula in the constellation Cygnus. It is also dubbed "Tulip nebula" because of its flower shape. It would take far longer exposures to capture more of the background nebulosity in the region. This is a natural color image taken through RGB filters and clear filter to enhance detail.

I recommend viewing the high resolution image:
