NGC6164/6165 HaOiiiRGB

[RickS]

Inspired by a few of the recent images including this little gem in the FOV I thought I'd have a go at reprocessing my 2014 data. I think it's quite a bit more subtle than my previous attempt.

NGC6164/6165 is a bipolar emission nebula (not a planetary) in Norma. The outer Oiii shell is very faint and it takes a lot of data to capture it well at long focal length.

Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB, 3nm HA, OIII, SII
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: 16x1200s + 38x1800s Ha, 37x1200s + 73x1800s OIII, 7x180s R, 7x180s G, 7x180s B
(1460m Ha, 2930m OIII, 21+21+21 RGB = 74.2 hours)

Cheers,

Maaaaaaate.... Very impressive! Totally nailed it. :thumbsup::thumbsup:

[billdan]

Rick very impressed, the bubble against the background wall of Ha just looks out of this world. Definitely something out of Startrek.

Geeeeeeeez, Rick, I'm speachlessssssss ....

[Placidus]

Just stunning. Excellent internal detail in the centre part of the nebula. Great depth in the outer shock ring and in the background. Lovely image.

[marc4darkskies]

What a great image! Excellent colour contrast and detail! :thumbsup: Well done Rick!!

Cheers, Marcus

[gregbradley]

That's a ripper image Rick and worth the repro.

I think you have shown the Ha and O3 background better than the earlier collaboration image.

This is on my wishlist for imaging with the CDK17 next time whilst its in such a good imaging position at the moment. Long focal length really suits it and your stars are so small as well.

Greg.

Incredible. The front towards the top of the image is reminiscent of bubble wrap. Very smooth.

[Andy01]

Simply the best version of that object I have ever seen! :eyepop:
Bravo Rick! :bowdown:

[Rod771]

Yes Rick! Bookmarked for sure, fantastic! :thumbsup::thumbsup::thumbsup:

[RickS]

Thanks, Peter! Would be a good target for the big Alluna.



Thanks, Bill.



Thanks, Ian.



Thanks very much, M&T!



Thank you, Marcus!



Thanks very much, Greg. I've squeezed a lot of images out of this data, but at 74 hours that seems fair :lol:



Thanks, Jerome.



Ta muchly, Andy.



Thanks, Rod.

[vlazg]

That is fantastic, something to aspire to

[RickS]

Thanks, George.

[SimmoW]

What they all said! Amazing

[alistairsam]

That's fantastic Rick. Superbly done.

Did you combine ha and o3 for the Lum?

Alistair

[RickS]

Thanks, Simmo!



Ta, Al. The luminance was a blend of straight Ha and starless Oiii.

[ozstronomer]

Fantastic image Rick, just love the O111 shockwave against the background

Well done :thumbsup:

Cheers Geoff

[RickS]

Thanks, Geoff!

[strongmanmike]

A lovely rework Ricki :thumbsup:...you're starting to challenge the number of reworks I did on my deep Cen A back 08/09 :lol: Love It! :thumbsup:

Mike

[Octane]

Magnificent.

H

[topheart]

I agree, one of the best renditions of this subject!
Well done!
Cheers,
Tim

[RickS]

Thanks, Mike. You have a few years up on me but I'll do my best to compete :D



Thanks, H. Good to see you're still around.



Thanks very much, Tim.

[Atmos]

That is magnificent Rick, not sure what else to say but :eyepop:

[Joshua Bunn]

Awesome Rick. It has a natural feel to it... goes to show how we improve our processing over the years.

Josh

[RickS]

Thanks, Colin :thumbsup:



Ta, Josh. Good to be improving. Hope I can keep doing it!

[DJScotty]

Great image Rick. Beautiful colours and detail.

Top stuff :thumbsup:

[Paul Haese]

Yep that is a better presentation of that data Rick. The nebula is bright and really nice saturation. Love those tiny stars too.

[RickS]

Ta, Scott!



Thanks very much, Paul.

[multiweb]

+1 Awesome Vista Rick. Subzero cool. :thumbsup::thumbsup::thumbsup:

[atalas]

As usual Rick....terrific! the shells are amazingly well defined.

[RickS]

Thanks Marc & Louie!

[Shiraz]

well that pretty much closes the book on that one - how can anybody ever hope to top this excellent image. I have been trying to get a bit of O3 on this region and am amazed at how much detail you have obtained - stunning.

[RobF]

Fav object, done to perfection. Top stuff Rick.
Going to Astrofest?

[RickS]

Very kind of you, Ray!



Thanks, Rob. If the weather looks good I'll be at AF from next Sunday through to the bitter end. If it's cloudy then I'll come up on Wed or Thu morning and stay until the weekend (since I agreed to do some PI sessions.)

[RobF]

Should see you there then.....

[RickS]

Great! Look forward to catching up, Rob.
