NGC 55 in hydrogen alpha. 9 hrs 2x2 binned (to get the really faint stuff) from 2018, plus another 4h30 mins unbinned (hopefully to get at tiny bit more bright detail) from last night.
The galaxy looks for all the world like a bread stick wrapped in alfoil, very crumpled, catching the light.
But on close examination, standing well off in a spiral around about the brightest, fattest bit (slightly right of centre) there is what looks like a band of tinsel or perhaps barbed wire.
One wonders if this is a tidal tail, or whether it is a structure supported by a strong magnetic field. If so, it's pretty nifty.
Huge amounts of star formation happening.
Full field here.
2018: Aspen CG16M. 9 x 1hr subs, 2x2 binned.

Field 34' arc, north up.
We're inspired to get more Ha, but it won't be
this new moon.
