Corona Australis (work in progress)

Hi team,

Here's 3 hours 7 mins 30 secs of my take on Corona Australis.

I hope to add more to it when the Moon is favourable once more.

Bigger version here.

Edit: I just noticed that I didn't mask my iteration of morphological transformation and the glob has suffered as a result. Oops.

SBIG STL-11000M, Takahashi FSQ-106N, Losmandy G-11 G
25x450s f/5.0 530mm at -20 degrees Celsius

Cheers!

H

That's a great start, H! The FSQ+STL11K has a great FOV for this object. Did you mention elsewhere that you were planning a mosaic? It would be great to see more

Cheers,
Rick.

Rick,

Cheers, mate.

Do you know if there's a debloom script for PixInsight? I will ask SBIG to fix my blooming issue while the sensor cover slip/chamber seal is being fixed. I was looking through old images where I had taken ten minute sub-exposures and there was no blooming. I seem to get them in my 450-second exposures now.

The mosaic I was working on was Rho Ophiuchus. I don't know if I will get a chance to finish it this year as it's starting to slip lower and lower. The GradientMergeMosaic process has had a very hard time blending my exposures properly (I'm following the proper methodology, too: register (mosaic/union) with frame adaptation, which makes my 4x2 scaffold, then, register (match images) each panel to the 4x2 scaffold (using previews for assistance), then run GradientMergeMosaic on the matched images). It seems to work well for the 3x2, but, falls apart when doing 4x2. It's not matching well, at all. No biggie, I will have to fix it up in Photoshop or weight via PixelMath on the pre-GMM'ed registered images using masks.

I don't think there is a good canned solution, H. I have seen some threads with suggested workflows for fixing blooming, e.g. http://pixinsight.com/forum/index.ph...34867#msg34867

Ah, that's right! A fantastic target for a mosaic.

I've only tried my hand at a mosaic once (the recent Veil in Ha) and everything worked well. I nearly have enough data to complete a Ha/OIII bi-colour now so fingers crossed that it all goes together smoothly.

Cheers,
Rick.

Looking really nice H, heaps of dust and I like the less traditional vertical orientation too

No debloom script that I've seen. Every time it's asked the response is to rotate camera and let image integration reject the blooming.

You just have to love the FSQ and 11000/11002 sensor combination. Great field of view H. Hmmm this has me thinking.

Yes, its a match made in heaven. Reducer on the 8300 just isn't the same when you do the maths. Sigh.

Beautiful work H!

Looking good H.

So much detail and so sharp.

I like the composition.

Good luck with it.

Ross.

Nice Job,

I Think its amazing that every white pixel is a star and realistically all those pixels are stars that are more massive then our own sun. It ceases to amaze me that that this image probably only accounts for a small portion of the stars that are really there including stars the same size as our own and dwarf stars 'Hot Jupiters'. It would be interesting to see an Inferred image taken of the same portion of sky for comparison.

The high res version is so sharp and detailed, can't wait to see this finished.

Cheers,
