At March 9 I managed to exposure about four hours of H-alpha light for NGC 2147.
I'll shoot more exposures for this soon to have more signal and colors.
There seems to be some rarely imaged faint looped shapes at bottom of the object, I haven't seen them before.
NGC 2174, the Monkey Head Nebula in Orion
A starless version
An inverted image to show the bottom filaments better
