HH 222 The Waterfall Nebula

Located in Orion. Accurate proper motion measurements of HH 222 reveal that the shock structure is a giant bow shock moving directly away from the well-known, very young, Herbig Be star V380 Ori

Blimey. Getting 15 hours of clear skies in Grimsby must have taken almost as long as the bow wave to move into that position!

I can't wrap my head around the scale of images like this. They just blow my mind. Thank you for sharing!

I started this when Orion crossed the meridian at 2 am, last night it crossed at 21:20! So its been a bit on and off for a couple of months, hence the heavy handed noise reduction ?

That is some faint nebula there Martin. As Ken pointed out 15 hours on one object, in a season ?? Great to see objects that are not normally shown on the forum.
