NGC2174 Nebula in Orion\
Emission Nebula in Orion
Uploaded 2/9/16

This large nebula in the northern part of Orion is much larger than our old film shots suggest, spanning several degrees and includes both emission and reflection nebulosities. This is one of the first shots with our new 10" f/3.9 astrograph and proves the Baader coma corrector does a great job at producing sharp stars right into the corners.
