Wow, this is a tough object. Tough to process and tough to capture.

My obervatory roof blocks the object after just two hours of imaging each night. The image has 5.3 hours so and the time to image it is running out for this year.

Processing for star colour needs some work I think as saturation is just not quite right. Pushing the blue results in the blue gas and dust looking un-natural.

See if you can find the galaxy too.

The satellite trails were also tough to remove, data rejection needs more work.

Thats dusty (and three satellite trails to boot ) but a really nice image Paul.
Galaxy at bottom edge 1/4 in from left hand side?

Thanks Allan you are too kind.

Three trails actually and yes your positioning of the galaxy is correct. It just seemed to pop out at me when processing. I wonder if all the dust just changed the star profiles???

A very nice FOV, Paul! I've only tried processing a very dusty area once so far, but I found it very tricky to get everything looking good at the same time.

Cheers,
Rick.

Nice one Paul! Well framed. I love the dusty blue stuff! An interesting object too! Does need more data though - double IMO - that will make it much easier to process.

Cheers, Marcus

Fascinating object. Let's hope you can get some more time in on this one. Might need to cut a flap in that southern wall of your observatory.

A very interesting object Paul. It looks like it would be challenging to process.

That's a lovely galaxy image Paul, if it wasn't for all that dust...
Nah, it looks really awesome, I like those wispy streaks and swirls and the colours are beautiful. Where do you find these stunning dust clouds?

Thanks all, appreciate the comments.

Marcus, I thought double too. Still some noise present in the data despite the long subs and the deep cooling.

Rolf, I did not find it I just took the idea from Greg Bradley who imaged this a month or so ago now. It is a fascinating region.

Graeme, maybe more next week when we go down to the house. Was thinking Monday might be good if that suits you. Tony is keen too for Monday as he has Space School from Wednesday onwards.

A very good photo Paul.

I really like the contrasts and composition.

Nicely done Paul.

The image scale probably doesn't suit it as much as a wider view though. Your STL11 would've worked nicely on this one.

Lots of detail, great tracking. Dust is tough as its always going to show the noise being so dim but noise isn't distracting. As always more exposure is better than less exposure weather permitting of course.


Greg.

I actually rotated this image 180 from the original capture orientation. All three images of this region on the net have the same orientation. Mine I wanted just that little different.

You are probably right Greg, but I think the 2.7" focusor on the TSA would be problematic with the STL11 and using a reducer. I could be wrong but I think I would get serious vignetting. What do you think?

I am now in two minds as to whether I should gather more data on this or commence my next image which involves the RC. Perhaps I could collect some more data and then change scopes? Maybe doing that would work better.

Excellent Paul, a pleasure to view . Sparkling, but with a warm analog feel.

It may be OK with the 2.7 inch focuser. Someone posted about using an STL11 on a TOA130 with 2.7 inch focuser and I expected vignetting but it turned out fine.

You'd really have to try it out as it could go either way. My experience was with an FS152 and 2.7 did not work out. But that was an older reducer and perhaps later ones work better.

Greg.

It certainly is a lot harder than it looks to process out dust like that. Great image Paul, particularly for a multi-night project as you describe.
