This is a smallish (36' arc) and not especially bright part of the central Vela SNR, near open cluster Pismis 4. It is much fainter than the Pencil nebula, but perhaps rather more interesting.
Big one here
Total exposure 24 hrs. Green: H-alpha 5 hrs; Blue: OIII 10 hrs; Red: SII 9hrs, all in 1hr unbinned subs. Aspen CG16M at -30C on 20" PlaneWave CDK.
The brightest star is the eye of a fierce yellow dragon, leathery wings filling most of the frame, blue flames trailing the body toward top right.
This image was pleasing to us because of the relatively rich and abundant SII, as would be typical of a supernova remnant. OIII on the other hand was very weak and largely confined to a single diagonal streak.
Notice also the roiling, boiling, bubbling blister-like texture through most of the top half of the image - big badda-boom!
This seems to be a rarely visited part of the sky. You might therefore like to compare with an
LRGB version by Don Goldman.
Best,
Mike and Trish
