Very fine in both senses. Beautifully done. Reminiscent of parts of the Vela SNR, where there be dragons.

Thanks, Martin. There is a lot of Ha! Almost no Oiii and a small amount of Sii...

Nicely done Rick.

It looks like a Supernova Remnant.

Thanks, Greg. I have found a couple of sources that say it resembles a SNR but nobody willing to say it definitely is one. There's almost no Oiii which seems unusual for a SNR.

That's a unique, rather beautiful and intriguing image Rick, nicely processed mate, the filaments are very 3D

Ta Mikey! Most of the credit goes to SH2-114 for being so photogenic but I did try to bring out the best in the data.

Here's the tiny quadrupolar planetary neb, Kn 26, in SHO palette and upsized somewhat. It's only a tiddler at about 35 x 80 arcsec in size.

Huh! Spotted that in the full res but in OIII dominant process (?) it looks more like a PN now

You're putting together some really unique images of late Rick. I really like the emphasis on the sharp edges of the shock waves. Lovely colour too which looks very much how film images once looked.

Lots of Ha and a little Oiii and Sii but I tried to make it look a little less green.
