NGC 602 in OIII

[Placidus]

NGC 602 is an open cluster at the edge of the small Magellanic cloud, surrounded by some faint nebulosity.

9hrs of OIII, 2x2 binned in 1hr subs to get the truly faint stuff. Note in particular the large but extremely faint super-bubble about 30% of the way to the right of the central brightest region, and an even more tenuous, somewhat larger super-bubble (asymmetrically around its own conspicuous open cluster) about half-way toward top left from dead centre.

The super-bubbles are not visible in H-alpha. Combining to produce an H-alpha OIII image tends to hide the faint OIII images. There is virtually nothing to see in SII, making it perhaps less likely that these bubbles are supernova remnant material, as opposed to pre-existing material, although that is a guess.

Mike and Trish

Kewel! Wow, and that super bubble is extra cool (can see the decon, shhh) Great stuff :thumbsup:

Man I gotta get out!!! I have major imaging withdrawals...don't wanna start boring the crap out'a you guys with any repros now do I :question: :D

Some amazingly faint stuff there, M&T. Very cool!

Cheers,
Rick.

Ah - I now see what Mike's comment was about. Excellent stuff as usual. Wish I had that OIII.

Cheers

[Bassnut]

wow, that super bubble is completely missing in my effort, well done and very cool!.

[Placidus]

Thanks muchly, Mike.




Thanks, Rick. It's the faint bits that intrigued us.



Thanks Steve. We need to do more H-alpha, as you have, but it's either full moon or raining.



Cheers, Fred. Took 2x2 binning and long subs to see it at all.

Fabulous Mike.

I took a test 10min exposure of this area a while ago for future image planning. Its an interesting area if done deep enough.

Greg.

[Andy01]

That's an awesome result.
Is there no way you could bicolour it with some Ha?
Or maybe just tone the O3 and add RGB stars back in - meh, nevermind, it's
probably just me looking to push your awesome image even further!

Well done guys :thumbsup:

Andy

[Ryderscope]

And all of that in OIII! Wow.

[Placidus]

Thanks, Greg. We'd love to know what the astrophysics of that right-hand bubble is. Could conceivably have been expelled by the bright star bang in the middle of the bubble. Perhaps it's a WR.



Thanks, Andy. We've collected some H-alpha, but need much more. Because it's pretty faint, for that we need for the clouds, haze, and the moon to go away at the same time.



Thanks Rodney. We drive through the speed camera at Glanmire once a fortnight, and look forward to your next image.

[RobF]

Awesome work. :thumbsup:
Thanks for sharing.

[Slawomir]

Wonderful and unique - thank you for sharing M&T :hi:

[Placidus]

Thank you Rob!



Thanks, Slawomir. We're greatly chuffed.

[Paul Haese]

Going deep there MnT. I am sure it will look nice with more Ha in bicolour. Nice work.

[Placidus]

Thanks Paul. Tonight it's cool, crystal clear, not too windy, but there's a gibbous moon so we're doing something bright, easy, and eight-legged in the LMC.

Best,
Mike

[LucasB]

Wow Mike n Trish! I love the depth in this image. It is a rarely seen view of this target.
Lucas

[Placidus]

Thanks, Lucas. Need to add some H-alpha now, I suppose.

[Shiraz]

very interesting image and investigation - not seen anything like this before.

thanks for the informative discussion too - triggered a lot of reading on a variety of topics.

[Placidus]

Thanks muchly, Ray. Glad you liked it and glad it triggered some interesting research.

Best,
Mike
