I prefer seeing this nebula north up. :D

Kitties hiding from bogeyman!

According to my pareidolia, she looks like the silhouette of MM in a mink coat in Men Prefer Blondes, with a microphone in hand, singing and dancing.

A large proportion of the YSO's in the LDN 1622 show characteristics of HH-objects. Could it be that the HH-objects simply mark a phase in star formation - I mean from every star? Or develops only certain kind of star jets, which become visible as HH-objects?

Where is the boogeyman? Under your bed?

Ha ha, no! The boogeyman is in the armpit of Orion, below Betelgeuse.

Phew, the smell!!! 😫
