SNR G206.9+2.3 in Monoceros

[gorann]

This is a very rarely imaged and quite weak Supernova remnant a bit east of the Rosette Nebula. It was shot in the morning of March 2nd under 70% moon, which is not the best for Oiii, and seeing was quite bad that night. Still my dual-RASA rig picked it up (it cannot for example be seen in DSS2 images on Aladin Sky Atlas). I was using the NBZ filter on one RASA and the Oiii filter on the other.

I was just pointed at a German site with some info about it: https://forum.astronomie.de/threads/14-woche-der-supernovarest-g206-9-2-3-im-einhorn.286227/

Dual RASA8 with ASI2600MC on Mesu200. 51x5 min IDAS NBZ (Ha+Oiii) and 51 x 5 min Oiii (Baader Hi-speed). So 8.5 hours in total. Processed in PI and PS including all the XTerminators.

Cheers, Göran

Never seen this one before, I would call it the Embryo Nebula.

Looking close in it has some red filaments which are separate to the background Ha?

What was that single cell thingy out of Star Trek called? The one where Spock went inside in the shuttle. That is what it looks like to me

Or Dividing Cell Nebula? Yes, I see at least one rather clear Ha filament that lines up with the Oiii filaments.

Wonderfully ethereal planetary.

Thanks Olly! It shows that there are still a few rarely imaged gems out there. I am sure it would be even more ethereal on a moonless night with a more steady sky. My RSM was around 1.5" that night, while it is usually between 0.5 and 1.0".
