NGC 2174 in Hydrogen Alpha
Size: FOV of this image is about 1 degree.
Distance: 6,400 light years
RA: 6h 09m 23.6s
Dec: 20 degrees 39' 33"
NGC 2174 is a region of hydrogen alpha emission located in the upper
portion of Orion,
near the boundary between Orion and Gemini. It is located near
IC433 in this
widefield view, and can also be seen in this widefield
view of the Orion region, both taken by Peter Erdman. The
darker dust lanes within this nebula, as well as its relatively compact
size, give it a superficial resemblance to NGC 281.
