See Stars Drifting Along: A look into the very dim Flaming Crown Nebula SH2-313

his is a very dim nebula in Hydra and was a challenge to shoot. Even at transit it is only 35degrees in the sky, decently small (10' across), dim(26.2mag/arcsec^2) and I have my neighbors roof to contend with.
What an intriguing object it is though! There is some debate on whether it is a planetary nebula or a Stromgren sphere . The central star is a binary pair of white dwarfs in a very tight orbit. This is one of the rare times you can see the motion of the stars through the medium. Especially in OIII you can see the wake it is forming as it is moving through the center part of the nebula. As with all debated objects in astronomy there is tension on whether it is proper motion of the binary pair through the central gasses or the gasses moving past the binary pair and interacting with the strong magnetic fields the white dwarfs are creating. Either way the visible motion is just amazing and something rarely seen. We are also graced with a plethora of galaxies and even a Carbon Star in the frame.

Recently discovered your channel! Although I dont own Pixinsight (yet!) I like watching your scripts and tutorials! Subbed!

Awesome, thank you!

Nice work.

Very Nice Frank, was this your standard set-up ? Greetings from sunny Spain

[@setiv2]

Yes that is my standard setup. I do have C8 sct i swap to sometimes, but going for dim objects I like the Orion 120ST with 0.8x reducer making it pretty fast at f4.

@@setiv2 And no problem with exposure of 900 seconds ?
