View Full Version here: : NGC 6888 in Cygnus

this was actually an experiment; one that can only really be done (I think) under great seeing. I wanted to see how the 5nm Ha and 3nm OIII filters would perform in the U16M and CDK under full moon conditions.
So, most of the integrations that make up this image are 1 hour in duration (as I said, you need really good seeing to do this) taken under full or near full moon. Obviously, target selection is important here as the same results would not be achieved if the target was in close proximity to a full moon.
Total exposure time is 16 hours (8.5 Ha and 7.5 OIII)
What impresses me the most was that raw FWHM on the 1 hour integrations averaged 1.8 asp.
thanks for looking

Strange object different

Amazing stuff Martin.
I have never seen that image before. Awesome.
Looks like a brain wrapped in some kind of jelly.
I will bet money this is another APOD.

Holy hell thats good, most images I see of this object are wide field. But this is stunning.

Hi Martin. What strikes me most about this image is the sharp detail and the three dimensional feel. The narrow band data really makes that happen, but combined with great processing the image is dynamic.
The colour could be more saturated in my opinion though. Dealers choice though.
Wow that is an amazing image!
It looks like an alcohol vapour fireball or something.

Very 3D and detailed as others have said. Amazing result with a full moon!

An amazing photo Martin.
The sharpness and clarity give it a 3D look.

That's a stunning and unique photo - well done.
I have seen this on a couple of up-north forums but nothing quite like this image. Agree with Paul, the detail is incredible.
Roll-on moonlit nights, roll-out the NB filters.Still cant find the cloud filter though..:(

Wow. Smooth as silk. You've set yet another bench-mark Martin :thumbsup::thumbsup:

That's an amazing image Martin - very 3D and the contrast in texture between the pink and blue is spectacular. Thanks for sharing.

Martin .... congratulations .... this is fantastic image.
Impressive read about the FWHM ...
All the best,

Hello and thanks everyone for the comments.

Wow!amazing structure Martin.
27-06-2012, 06:01 PM
Thats AWSOME, looks like fancy SFX.
27-06-2012, 07:29 PM
Martin, this may be the best 3D looking image I have seen. Very impressive detail.
27-06-2012, 08:38 PM
Fantastic O3, I use the Astrodon 3nm and it is suprisingly noise free.

This image is splendid
It's a super good job !!!
28-06-2012, 08:39 AM
Excellent image with extraordinary detail captured with 1 hr subs! Spectacular!
28-06-2012, 09:37 AM
Yes, the 1 hour subs came out really well!
28-06-2012, 11:30 AM
I think that's the best I have ever seen of this one, it's just beautiful. The wispy blue that wraps all around really tops it off, very well done!
Looks like there is a big fat bok globule just under the central red star, interesting.

Hi Martin, missed this one. Is the link still working? Cannot get to the image..
28-06-2012, 06:35 PM
Thanks again for the posts.
Marco....link is good. Here it is again :)

Martin as usual another surprising image and under difficult conditions.
A great result thanks for showing
