Radioactive Prawn

[Slawomir]

Hi all,

Sharing another narrowband image from Paddy in Brisbane.

I am not quite sure yet about the colours and brightness; this image looks quite differently on my ipad and on computer screen :shrug:

Nearly 20 hours worth of 15 minute subs.

Thank you for looking!

Love it Suavi!
Dramatic, colourful, great framing, well done :thumbsup:

[marc4darkskies]

Gorgeous Suavi! :thumbsup: Colours look beautiful and nuanced to me!!

[Atmos]

Very nice Suavi. There is something that you can do with 20 hours of data that I just cannot do with 4 hours! Excellent image.

[Slawomir]

Thank you Andy. I was a bit unsure about the colours - so I really apreciate your feedback :thumbsup:



Thank you Marcus. So I will will the image as is :)



Glad you like it Colin.

But I thought that unlike ancient & noisy CCD technology, CMOS with its ultra low read noise does not require long acquisition ;)

[Placidus]

Just awesome. Something to aim for.

[Octane]

Well done, Suavi! That's come out really nice. You must be very happy with your new scope. :)

I'm also on this one at the moment. Just collecting the last of the LRGB stars. Looking forward to finishing it off, too!

Ahem, I note the winky eye, but in case there's any innocent bystanders around, you're being a bit evil here. The missing bit at the end of your sentence should be: "per exposure". You still need the overall exposure time, it's just that these CMOS cameras help fill up the hard disk faster with more images to process. :)

Back on topic: Nice image, definitely better going to the astrobin link to see it than the cut down version here.

I really, really like the SHO implementation here Suavi. To turn this into a superb image, I would suggest you isolate (mask) the main nebula and apply curves or histogram transformation to brighten the background a little.

BTW, IOS cannot interpret sRGB colour palette so images will always look dark and clipped on an iPhone or iPad - its not your processing.

Thank you all for such wonderful feedback. It took me over 10 nights to collect this data (I have extremely limited views on the sky), so a pleasing result is a nice bonus :)

Thank you Martin for clarifying that it is IOS not reading colours correctly, and for your advice - I have brightened the background a tiny bit and the image does look better :thumbsup:

[Octane]

That looks even better!

Wow, Suavi. You knocked that one out of the park! Is this one of the first images from your new scope?
The high QE of your Sony 814 sensor is showing its strength here. Tiny stars as well. Solid colour, no noise. A wonderful image.

A great ad for the CFF scopes as well.

Your best ever.

Greg.

[Atmos]

The lightening helps :)

[strongmanmike]

Excellent Prawn there Suavi, enjoyable view and time well spent mate, take a :prey2: :thumbsup: My only minor suggestion is, to me it looks like you have washed out/de-saturated the colour a bit in parts of the nebula, perhaps as part of the desaturation of the stars, or from colour noise removal..?

Top job none the less :)

Mike

[Slawomir]

It was Martin's excellent suggestion :)




Thank you Greg. Yes, it's my second proper image with this telescope. I may yet fine tune the alignement/tilt, but so far I really like my new instrument.



Thanks Colin!



Glad you like it Mike and thank you for your comment. Actually I did not desaturate this data at any stage, but OIII was very weak so I had to stretch it a lot and more to get any meaningful info from it into the RGB. So I had to apply noise reduction to OIII (and SII) but only at linear stage before combining them into an RGB image.

[Regulus]

I like it, and there doessn't appear to be detail lost in the brightest parts.
looks great.

Hi Suavi

now, it is a superb image.

very well done.

cheers
Martin

[Chris85]

Unreal image, loving the colours on this one. I'm slowly collecting data on this myself, although by the time it clears in Perth it'll probably by too far gone!

[SimmoW]

That's lovely, detailed Suavi! And epic effort too. Makes me feel guilty for having over 20 degrees of view!

[RickS]

A most excellent, well cooked Prawn, Suavi! I hope to see it as an entry in the AAQ Astrophoto comp :)

[Slawomir]

Thank you Trevor.



Thank you Martin for your advice and encouragement.



Glad you like it Chris. Hopefully you will get at least a few more clear nights, but can always add more data next year :)



Thank you Simon. Yes, it can be a bit of a struggle to get enough data when we both have limited sky views.



Thank you Rick for your kind feedback and for reminding us about the AAQ astrophoto showcase :)

[vlazg]

Fantastic image Suavi, congratulations on the result, superhuman effort over 10 nights.

[mountainjoo]

Striking colours and tight stars as always, nice work.

[atalas]

Goregouse!well done Suavi :thumbsup::thumbsup::thumbsup:

[Paul Haese]

Nice Suavi, colour and detail are quite nice. Composition works too in my opinion.

[Slawomir]

Thank you George, Jerome, Louie and Paul :hi:
