A nicely twisted galaxy. NGC 2442 in Volans. We were motivated to do this after seeing Lee's (CodeMonkey's) very fine version.
FLI PL16803 on 20 inch PlaneWave. Lum 7.5hrs. RGB 6 hrs total, over 3 glorious nights this new moon.
As usual, all robotics and all processing software designed built written by us in-house. Nothing bought at a restaurant.
The thumbnail is a tight crop. The FULL FRAME IMAGE shows at least 55 distant galaxies, most showing quite detailed form, as the galactic police would say.
A very interesting image. I always thought that galaxy was a spiral in one plane. Your image makes it look more like a twisted spiral like a propeller.

Your image is quite 3D.
Greg.
Thanks Greg. ESO says 'its distorted shape is most likely the result of a close encounter with a smaller unseen galaxy'. Sadly, I can't find anything about whether it is all in one plane, but it sure looks twisted out of the plane.

That is the most wonderful apposition of Homers. Thank you!
Thanks Allan. There's an intensely blue star in our shot. We wondered if it might be a quasar. It's intensely blue in Mike's shot too. It's so nice when two red-hot experts agree!

Great galaxy image guys .. it's the weirdest looking spiral huh? Love that detailed dust lane along the long twisted main arm.
Mike
Thanks Mike. I'm giving my tiny lunch box a clean even as we speak.
According to this article, the most likely "culprit" is the very conspicuous and funny looking fellow AM 0738-692, which is toward 10 o'clock and almost at the edge of the thumbnail. The article points out that AM 0738-692 also has not spiral arms but a pair of strong tidal tails pulled out of it, that just look like spiral arms. So quite an interesting galaxy in its own right.
The article also says that h-alpha is strongly concentrated in the star-forming part of the spiral arms of 2442. Perhaps next year we might try photographing it in H-alpha.

I knew it! I just knew it! that bloody little AM 0738-692 causing disturbances again! it comes poncing in, runs a few rings around a larger galaxy, who is just trying to meander out quietly with the expansion of the Universe, minding its own business...and then the blighter leaves after lifting the skirt of the big galaxy, just for laughs. Sheesh.. annoying little bugger
There are so many good things happening in this image MnT. Wonderfully detailed galaxies well processed with lots of interesting technicalities to ponder
