HI All,
I have finally had a pocket of time to process some data!!
Man, my processing is even rustier than before!

https://savannahskies.smugmug.com/Nebula/i-9KsRH39/A

0.5M Classical Cassegrain on a PME2 mount. STX16803 with AOX guiding at around 6 to 8 Hz.

HaO3LRGB image.

Data obtained through May and June 2017.
Just looking at the folder of calibrated images I see there was 66 hours of data all up.

Regards,
Tim

Sub zero cool!

[phomer (Paul)]

A very interesting object.

[Joshua Bunn (Joshua)]

Very smooth Tim, nice colours.

That’s a gorgeous image Tim, I don’t think I’ve ever seen so much detail in the outer shell before. In fact I’m not sure I’ve seen that outer shell before!
Cheers
Andrew.

Great detail in the nebula itself, but after 66 hrs I would expect that the outer shell would be much better defined and brighter?

Lovely star colours too

Excellent image quality Tim

A phenomenal image Tim. If boosting the shockwave meant losing some of that gorgeous detail in the neb itself then I think its a good tradeoff to keep the detail.

I think I finally understand where I have been going wrong.... I only put a tenth of the integration into targets

Wonderfully deep image Tim, shows regions and depth that most others don't quite reach

Yes!! You guys have picked what has been driving me crazy with this image!! I do see a much denser outer shroud in the NB data that is toned down in the final image here---I am still playing with the data to try and show the star colours and the detail in the central nebula as well as the brighter outer shell....I will hopefully have a second version to post if I don't get put into a straight jacket first...

Thanks to everyone who has commented!
Cheers,
Tim

Great detail in the central shell, Tim, and a stunning image.

How much time did you spend on the Oiii, Tim?

Cheers,
Rick.

Hi Rick,
With the O3 there is about 10 hours of data.
I have uploaded a thumbnail of the mean O3.

Thanks, Tim. The APOD is a combination of Martin Pugh's data and mine. I collected over 36 hours of Oiii. That outer shell is a dim sucker!

Cheers,
Rick.

The detail within the nebula is gobsmacking.

[Placidus (Mike and Trish)]

Yes, what Geoff said: Gobsmacking.

[Stevec35 (Steve)]

Incredible - the central part is the most detailed I've ever seen for this object.

Cheers

Steve

Thank you all very much.
I will keep trying to balance the core with the outer shell some more.
Cheers,
Tim

Holy Smokes!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!

Big scope: tick
great skies: tick
superb camera: tick
adaptive optics: tick
expertly processed: tick

Not surprising this a one heck of an image. Well done!

Thanks very much Lewis and Peter.
