![Herschel's Ring is a nebula produced by the stellar wind from a super-hot Wolf-Rayet star ploughing into pre-existing medium.
Red: [SII] 10hrs, Green: H-alpha 5hrs, Blue: [OIII] 6hrs, all in 1hr 1x1 subs..
Field 36'arc, North up. Aspen CG16M on 20" PlaneWave.
As befits a WR rather than an SNR, there was very little SII in this image,](https://photos.smugmug.com/Category/Wolf-Rayet/i-mTVpZF6/0/dc9d713d/M/Hershel%27s%20Ring%20Ha%205%20OIII%206%20SII%2010hrs-M.jpg)
![Eagle nebula. 15 hrs narrowband. Red: [SII] 6hrs, Green: H-alpha 3hrs, Blue: [OIII] 6hrs. Aspen CG16M on 20" PlaneWave CDK, on MI-750 fork.](https://photos.smugmug.com/Category/Star-Forming-Regions/i-rcKGQ2j/0/20c39705/M/Eagle%20Ha%203%20OIII%206%20SII%206hrs-M.jpg)
![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/M/Mermaid%27s%20Pantry%2C%20NGC%20456-M.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. Aspen 16M on 20" PlaneWave.](https://photos.smugmug.com/Category/Star-Forming-Regions/i-qWZRK52/0/46793d2a/M/0066%20NGC%20300%20etc%20SMC%20Ha%205hrs%20OIII%205hrs-M.jpg)
![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/L/0051%20Snoopy-L.jpg)
![This is a low-res caption for the main image. Note the three mythical animals, all in right profile, all strong in [OIII] (blue). I take the location of the SNR (very strong in [SII]) from Kavanagh PJ et al, XMM-Newton Observations of the N 206 Superbubble in the Large Magellanic Cloud. Sources for the animals are harder to track down.](https://photos.smugmug.com/Category/Supernova-Remnants/i-d7Fzc4f/0/de6d1bbc/M/Annotated%20version-M.jpg)
![Henize 206 in the Large Magellanic Cloud. See separate key image for location of the magnificent supernova remnant at 10 o'clock from centre and about 40% of the way out and strong in [SII]. Numerous shock fronts, very strong in [OIII] blue) suggest a menagerie of mythical creatures al in right profile.
H-alpha 6hrs (green), OIII 6hrs (blue) SII 6hrs (red). STL-1100M on 20" PlaneWave CDK on MI-750 fork mount.](https://photos.smugmug.com/Category/Supernova-Remnants/i-M689Cr8/0/719c5962/M/Henize%20206%20Ha%206h%20OIII%206h%20SII%206h%20E1-M.jpg)
