A faint and obscure SNR: RCW 114


4 segment mosaic
7.5 hours each segment
5nm Ha
FSQ
Proline16803
Coonabarabran, NSW
There is little if any OIII in this object, and SII is nearly non-existent based on spectroscopic studies of individual filaments. So I concentrated on H-a only for this production. It's rarely imaged if ever by amateurs, but astronomer's know it from SNR surveys of the southern sky in search for ancient remnants of exploded stars.

Enjoy the ride!

Very cool, John!

That's fantastic John!

What is the RA and Dec for that gem?

H-alpha is often under-rated...Great shadow and highlight handling of a rare subject. Not sure why excellent images like this are not more popular.....:question:


Very cool image :thumbsup::thumbsup:

Super image John

Thank you everyone!

A very impressive image John. Not just for it's quality but for hunting down a faint obscure extensive SNR. I may if I get the chance to see what it looks like in NII and HA.

I used Registar with your image to show its position and extent. Right under our collective noses on the tail of Scorpio!

Cool shot John. :thumbsup: I had captured it in one of my widefields (https://public.bay.livefilestore.com/y1pyi0Tpg4MslGgOm0u1Ays8Sr9yfyGRfRU KDfgCq3xuvkLvIu7Y-zS3-hcQdGSit8hFDl9W7bgjC1tQSun0FGprg/milkyway_ha_aratoscorpius_ff.jpg?ps id=1)before but never really noticed until Brett pointed it out.

Thank you Bert,

There has been research on faint SNR's in the southern milky way from the UK Schmidt Telescope. In 1999, I met one of the principal investigators at the UK Schmidt, working on the ancient SNR survey. Waht a fun project. I think I was more impressed with the gigantic Ha filter they had for the Schmidt camera to do the survey.

Scanning my recent Scorpius mosaic, I have found several faint SNR candiates that were catalogued from the Ha survey.
