Helix 10 hours 40 mins CDK17

gregbradley · #1 17-09-2011, 09:23 AM

Here is one I took a while ago and just finished the processing.

Taken over a couple of months. I took the Ha and O111 early on and then a few nights of LRGB.

The aim was to bring out the outer nebulosity not often seen and the spiky O111 centre.

A very faint but spectacular object worth the effort.

Planewave CDK17 at F4.45, Proline 16803, Paramount ME. Taken from my home observatory in Kurrajong NSW.

What a jaw dropper!
Spectacular work. So 3d.
It's got everything going for it.

Not much nebulosity left to capture! Nice work

Hi Greg

Very deep overall image with a nice 3D appearance there that you don't often see in Helix shots. The central part is particularly pleasing. A top shot to be sure.

Cheers

Steve

Excellent Greg, and one of the most beautiful objects in the sky, i reckon, well done mate.

Cheers JJJ. The reducer on the CDK makes all the difference with these faint objects.

I imagine 100 hours would pick up a bit extra around the very very faint perimeter but not worth the effort or the clear skies it would cost!

Thanks Steve. The deep Ha and O111 give the detail, all binned 2x2 which seems to suit my scope and camera.

Thanks Leon. I think so too, it definitely has nice colours and a wild shape to it.

Stunning Greg. Simple as that!

Pretty hard to fault, I like the starburst effect, I have seen it once or twice before, from memory it's to do with the O 111 data.
There has been a marked difference with the helix shots of late, a hint of that second shell used to be all that was displayed now it's full on with the third just showing..... Where to next ?

The trend is definitely trying to go deeper and deeper.

An amazing image, Greg!

John Hothersall · #17 17-09-2011, 05:36 PM

The Ha is very deep and the O3 is starting to show those elusive rays through the ring, I think this is a splendid result. Interesting you binned the NB but it does not seem to have affected the final result.

Lester · #19 17-09-2011, 07:38 PM

That beast of a scope is really performing, outstanding view. Thanks Greg. All the best.

Meh, seen better. NOT.

That image is a belter!

What are you going to do with it?
