Images Processed with StarTools

[avandonk]

I have been using StarTools for just two days. Here are some images I processed with StarTools.

NGC6164 in Narrow Band Hubble Palette 18MB

NGC6164 in blended RGB and NB 12 MB

Lambda Centauri in NB 13MB

NGC 6334&6357 in 3nm NII 6 MB

Only the last used any HDR in StarTools and even then it was a careful blend with a normal image so as not to offend the more sensitive eyes out there. :)


Some notes.

The contrast module seems to totally eradicate any gradients.

All images were sharpened, deconvoluted and noise reduced. All these operations do not seem to have any visible artefacts.

The images speak for themselves.

Ripper images Bert! My favourite of the bunch would be the narrowband version of NGC6164. This area of the sky is so fascinating at different wavelengths. Always something different to absorb and ponder on.

Something to consider. Given your 3 arcsec/pixel sampling I would stay away from deconvolution. Deconvolution comes into its own with oversampled data, not so much undersampled. This may lead to the stars becoming brighter which is really the opposite of what you want to achieve if presenting maximum nebulosity across wide fields. Reducing star sizes and brightness enhances large structure as the stars are less of a distraction to the viewer. Of course everyone has they own method and there is no right or wrong.

Well done. More please :thumbsup:

I'd also be keen to see that continuum filter given a work out. Should present stunning views of billowing nebulosity. What filter does it match, only your Ha?

Great collection Bert. You're on fire! :thumbsup::thumbsup::thumbsup:

[strongmanmike]

The new improved Bert :hi:

Here we goooo! hold on guys :thumbsup:

Awesome Bert! Thoroughly enjoyed those results. The nebulosity is real knock-out material. Really suits your set up with a large FOV. A mosaic of the complete Vela region does in this fashion would be explosive to see.

Astounding images, Bert. I've not seen anything at all like them. Love the processing and Jase does have a point, but they are really beautiful images in all senses of the word.

You are quite correct Jase and Allan. Here is a version of Lambda Cent in Hubble NB palette with no sharpening or deconvolution.

All I did was process each NB fit independantly with StarTools and then recombined them into a tif. What is interesting is that StarTools eradicates gradients if you process this way. More on this later.

Mike and Marc here is just a taste 10MB

StarTools really handles noise suppression well without losing detail.

Very impressive Bert
Looks like your a fanboy of Startools and how it processes your data.keep them coming, Allan

[avandonk]

I am not a fanboy of anything. Only what works after objective evaluation!


What is really useful is that the stretching in ST is very intelligent, much better than us fallible humans.


I have a lot of images I will post in the next few days.

Absolutely amazing work Bert!

WHOA!!!
This is just ridiculous amount of faint stuff you are picking up Bert. And no less than from (nearly) downtown Melbourne!
Incredible.

StarTools is quite a package. Images are stunning.

[gregbradley]

That's quite a pleasing colour scheme you achieved there Bert. I quite like the golden look.

Greg.

[jase]

The golden chook is growing on me, Bert. Mid tones and highlights are working well. Shadows are a touch too dark for me resulting in a higher contrast being presented. Seasoned to taste of course and if everyone's taste was the same, such images would be monotonous. So its good to see a different perspective. Keep them coming. :thumbsup:

[Bassnut]

This is just insane, jaw dropping, well done Bert.

[Rod771]

Fantastic images Bert! :thumbsup:

That's a very nice set up.

I may missed it :question: but how long were each of your exposures? (on average)

Cheers
