Interesting composition, lovely colours and Rick's perfect processing. In short, extremely high standard that we would normally expect from you Rick

The only thing that could be further improved is to do with optics/mechanics - star shapes in the top right and bottom left could be better. But I had to look VERY closely to spot that

Thanks, Suavi! I almost turned it upside down to look like tonsils instead of an elephant's trunk

You are correct about the star shapes. The problem with a remote scope is that tweaking collimation and camera tilt is inconvenient at best. The last time someone drove out to work on it it clouded over For now we'll have to live with the imperfections.

Thanks, Scotty! Working with the SRO data is a real pleasure. Of course, it's still possible to make it look terrible... with the awesome power of PixInsight

Really nice Rick, quite an interesting region. In most of the region there isn't much in the way of hard edges, largely just gradients of gasses from one region to another. Very nicely handled.

The full res is stunning. The structure of the trunk is so clear.

No fair showing off all these northern targets. This one seems to love being shot in narrowband/Hubble palette. Jealous as.

That's very impressive, a great image Rick. Flawless processing indeed.
Inspires me to do some more narrowband once my obs is ready

Lovely shot Rick, you have showcased the subtle variations produced by the three main emissions nicely One of those images that inspired a good long pan around and look, the sort of look that is usually reserved for busy galaxy fields - nice work indeed

As for the wonky stars identified by Suavi......even with the full res version open and even then, with my over sensitive dceonwavelette detectors on full.. I had to look pretty hard to see what he was talking about (I think he is a bit loony... like me )

Mike
Love you Suavi

Thanks, Colin. It's certainly interesting how the ionised gases are distributed. I'm sure it's even more complex than it looks from our 2D view.

It's a tough gig but someone has to do it, Troy It certainly is one of those objects that just works in SHO!

Ta, M&T. It seems unfair that we can't see everything.

Thanks very much, Mike. I did do a little decon and hoped it was subtle enough to sneak past you

Another great image. Anything special about the processing you did here? How did you mix it?
