It looks like you used Eric's data there Peter!

Hubble, plus a tad of Keck and VLT :)

P.S. I doubt the slight background brightness variations are hints IFN....
probably the neighbours DFF (dammed ......g flood-light)

Stunning detail. Adaptive optics using xi 1 Centauri as the guide star at 20 frames a second?

I wish I could produce images with that sort of contrast. Wimper.

Best,
Mike

That looks fantastic Peter, the 16" is certainly showing what it is capabile of :)

A sweet image Peter! Great detail - nice and crisp! :thumbsup:

I know it sounds a bit sacrilegious, but I'd probably reduce the dust induced red cast a bit to make the colour nuance in the galaxy pop a bit more.

Hi Peter,
you have extreme detail there.
That Alluna RC 16 is an amazing scope.
Imagine if you set it up away from the city lights!

cheers

Thanks for the input guys.

Marcus...I agree..backed off the red a tad. (Same URL)

Looking nice.
Certainly better than many other I've seen of this target

Now you're talking, "pop" has been achieved! Very nice indeed!

Great image, Peter. Looks much better with the colour adjustment.

I'll thank Marcus for the hint...interestingly it now better matches the AAO's stock image of this galaxy.

Holy Dooly Peter that is awesome. Very sharp and I like the colour.

Bigger please. I want to see the tendrils of gas and dust.

Colour still looks a bit magenta to me. Detail is good though.

You make it look too easy. I like the repro, great details as usual. :thumbsup:

Thanks Marc. Ah... I wish it was easy! The ever increasing light glow from Sydney makes my urban imaging more difficult with time. I've also much more work to do due the fact I'm now using an instrument rotator.

Fantastic for acquiring bright guide stars, but now I need flats for each unique camera rotation angle.

While I prefer sky flats, I suspect I'll need to migrate to a softly glowing El panel soon (sigh...more expense! ) for timely calibration frames. If you push my recent effort (above) to the nth degree, you'll see radial illumination background changes, which simply are due the flat fields being a few degrees off....More exposure time would good, plus a larger scope, larger dome, better seeing....:lol:

Ta Paul....might tweak it a bit more, but I think you already know I don't do HR on the web.



Thanks. I admit some photons were culled via a tiny bit of decon ;)
