Horsehead, bright nebula NGC 2023, and (at least three, probably four) Herbig-Haro objects (circled). H-alpha, 6 x 1hr subs. Aspen 16M on 20" PlaneWave CDK on MI-750 fork. Field 36 min arc, North on the left.
A Herbig-Haro object is formed where a polar jet from a young star slams into pre-existing material producing a mushroom cap on a stalk. These four are too distant to see any detail. Easier examples are seen in the Trifid nebula and in Master Yoda's Walking Stick in Corona Australis.
Clearly a sea-horse, emerging proudly from the salty spume. Observe the small rhino horn on the horse's nose. As well as an obvious set of reins, bits of kelp are hanging from the horse's mouth. Tastes vary. The horse is observing a Loch-Ness style sea-serpent, riding the breaker to the horse's left.
