Tarantula
Tarantula in Greater Magellanic Cloud. Red: 2hrs [SII]. Green: 2hrs H-alpha plus 2hrs [NII]. Blue: 2hrs [OIII]. North up. The site of SN 1987a (unresolved) is marked at bottom right. In H-alpha it is a tiny green smudge. In [SII] it is two stellar dots.

![NGC 2467. A bright emission nebula in Puppis. Without much imagination one can see the dog Snoopy, more or less facing the camera. To the lower right is a frothy complex emitting in [O-III].](https://photos.smugmug.com/Category/Star-Forming-Regions/i-rfpRtD3/0/4caf80b0/Ti/0051%20Snoopy-Ti.jpg)
![A rarely photographed region in almost the exact centre of the Small Magellanic Cloud. The tiny globular cluster at top left is NGC 330. The other structures are faint and not in the NGC. Yellow: H=alpha 5hrs. Blue: OIII 5hrs. Various large disrupted ring-like structures are seen. Notice in particular the scalloped, gold filigree shock wave complex at about 1 o'clock from centre, which (speculating with little evidence) could be part of an old supernova remnant. The field as a whole is very faint in [SII] (not shown) but the filigree is visible in [SII]. The small, bright yellow arc at the top right edge is intriguing. Field 36' wide, North up.

![In the SMC, we find a Mermaid's Pantry, a cavern surrounded by gently waving brown sea-weed. At centre, probably creating the cavern, is open cluster NGC 465, comprising perhaps 50 small hot stars. At 6 o'clock is NGC 456 in the shape of a blue strawberry with a yellow hull.. At 2 o'clock from 456 is a Hawksbury jellyfish, swimming to the left. At 2 o'clock from centre is the head of a dolphin, mouth agape, also swimming left. Note very faint [OIII] shock waves around a large bubble at about 1 o'clock, and another large super-faint H-alpha bubble around 8 o'clock. (The mermaid herself requires a lot of imagination but the two bright blue structures between 456 and 465 might be part of her). Yellow: H-alpha, Blue: OIII 3 hrs each.. Field 0.5 deg, North at right. Aspen 16M on 20" PlaneWave CDK.](https://photos.smugmug.com/Category/Star-Forming-Regions/i-bwDMD8J/0/7dd5bde9/Ti/Mermaid%27s%20Pantry%2C%20NGC%20456-Ti.jpg)
