I took this last weekend in reasonable seeing.

Ha O111 LRGB image. 9 hours and 20 minutes.

Nice one, Greg! Good detail in the core and showing a lot of the outer shell.

[topheart]

Yes!
I agree with Rick.
Well done!
Cheers,

What Rick said

[Slawomir]

Looks awesome. You have beautifully captured the swirly clouds of ionised gas around the central star.

[markas]

Great shot! You've got the outer OIII shockwave, which is not so easy....

Nice shot Greg. This is not a planetary nebula though. It's actually emission from an O type star.

Wow the detail in the core and outer shells is fantastic Greg:thumbsup:

[Peter Ward]

Nicely done. Great image scale and details. :thumbsup:

[gregbradley]

Thanks Rick.



Thanks Tim. I had already decided to image this one before you posted yours just so you know I am not stalking you (no need for an AVO hehe).

Its quite different from yours as its more of a narrowband image. You must have gotten a lot of RGB data and I like that colour in the nebula as well from RGB.



Cheers Geoff.

Ah thanks Steve. I should've looked that up before I posted it. I'll correct it.



Thanks Louie. I am very happy with this Microline 16 with its 6 micron pixels. I thought it would simply lose sensitivity but even at .43 arc secs image scale the scope and conditions are keeping up with it.



Thanks Peter. I did spend a lot of time processing this and its quite a complex image. You tend to lose perspective when you spend a long time in one sitting. I left it for a while and came back and the original was way too saturated so I corrected that.

Hi Greg,
Yes, it is interesting how the predominant NB data changes the balance of things. I like your rendition.
Cheers,

Hi, Greg,

You've achieved great depth in the outer OIII shell, showing not just the brighter bits but lots of detail. In the central region, there is an intriguing inverted cone or funnel structure that I always look for. In your image it is immediately above the central star. You've got quite a bit of fine microstructure in the cone. Superb!

Best,
Mike

[gregbradley]

Yes the NB data definitely makes a different look. Thanks.




Thanks Mike. I have been surprised at the level of extra resolution the CDK has given with the Microline 16 camera. .43 arc sec is a pretty tight image scale. I know you are imaging at even less at .39. Good seeing becomes very important with those figures.

That is different looks good Greg great detail

Looks great Greg, a fascinating target too, well done! :thumbsup:

Thanks Martin.

Nicely done Greg. Heaps of fine details. :thumbsup:

[gregbradley]

Thanks Marc. I have been very happy with the resolution the Microline 16 has been getting on my CDK17.

I've been informally calling it "the Megaphone" for a while :lol:

[gregbradley]

Yes I only first noticed that on Tim's very very detailed image. So I was looking to see if it showed up in mine. Previous attempts did not.

[Paul Haese]

Nice work Greg, the detail is excellent.

[gregbradley]

Thanks Paul. I am happy with the result.

Greg.
