[Peter Ward]

New!

Improved!

...well... Re-processed

(With some expert input from one D. Malin....for which I am very grateful)

Hope you enjoy the encore view!

Such lovely an intricate details Peter
Not sure if it is my eyes, my monitor or a combination of both but some of the whiter stars around Eta Carina appear to have a bit of a green tinge?

[Craige]

Stunning!

[h0ughy (David)]

lovely, ruddy beautiful

[gregbradley]

A great image even better. What did you have to do to the bright stars?

Sigh...a processing artifact.... I was oblivious to...but basically amplified noise. Sometimes you don't see the forest for the trees

Shouldn't be any green ...but I'll investigate...and appreciate the input.

Stunning image, the clarity blows me away. Congratulations on your award.

[Mighty_oz (Marcus)]

Sublime

[Stevec35 (Steve)]

Hard to see that ever being improved as an Eta Carina view Peter

Cheers

Yes, truly sublime Peter! Incredible detail! What's the image scale of the displayed image? What are the sub exposure details?

[Placidus (Mike and Trish)]

If I came across this image not knowing its provenance I'd think it was the best Eta I'd ever seen. The colour is lovely (not too magenta) but it's the razor sharp detail that does the trick.

[speach (Simon)]

Ho! yes

Thanks to one and all above for your kind comments.

The Alluna's native resolution is around 0.6 arc/sec per pixel with the STX...which is what I used for this image. The original was around 4000 pixels wide, but this was re-sampled to 1920HD size for the web.

Being in the suburbs, I use loooooong subs. Typically 20 minutes for RGB and 30 minutes for Halpha. The downside is I often get aircraft and satellites in the data, that no amount of pixel rejection will remove

SBIG's AO-X + Alluna's massive AFFC corrector is what really helped with the data....I had a run of sublime data with perfect stellar profiles to the edge of the sensor...this is *really tricky* with KAF16803's... they show even the slightest tilt or curvature that would be invisible when using a smaller chip.

The other piece of "white man magic" I am slowly relying on is Pixinsight's DBE tool.. Getting to understand this software is rather like bamboo-spikes under the fingernails...but once you more past the pain barrier it is a remarkable tool and well worth acquiring if you image in a light polluted location.

[Peter Ward]

The attached image gives a better perspective of the size of field corrector I referred to earlier....a serious optic!

[LightningNZ (Cam)]

That's incredible Peter. I feel like I could "swim" through that detail for days.

[Andy01 (Andy)]

No exaggeration, that's the single best amateur deep sky image I've ever seen. Thoroughly and deservedly winning it's Malin Category.

I went looking unsuccessfully for your original version, to see what changes you made following Dr. Malins' input - would be an interesting comparison for us all to learn from.

So maybe we need a section here on the forum for "Benchmark images" of various subjects - this would surely be the definitive image for this one.

[traveller (Bo)]

Wow, what a mesmerising view, loved the Finger of God!

Cliché alert - you have improved perfection.
So much sharper and richer in colour.
May i ask what you used to sharpen the image?

[alpal]

Hi Peter,
I still think it's the best picture ever posted on Ice in Space.

However - I am having trouble seeing the difference between this
& the original APOD:
http://apod.nasa.gov/apod/ap160527.html

Maybe it's slightly more colourful & sharpened better?

cheers
Allan
