M27 - Narrow_Broadband Combination

Martin Pugh · #1 31-08-2011, 12:10 PM

Hello all
I wasn't actually going to post this image, since the data was collected during the days following the initial set up at SRO, when guiding and focusing were being tweaked and then there was the build up to full moon. The initial intent was just to blend RGB stars into the NB data, but that thought went even further when I started blending OIII and Ha into the RGB star data. That produced an astounding image all on its own, even before I started to add in the 3-filter NB data.

Image details:
Telescope: Planewave CDK 17”
Camera: Apogee U16M
Filters: Astrodon
Exposure Details: R(15mins)G(15mins)B(15mins)L(Syn)(7 10mins)SII(370mins)Ha(160mins)OIII( 180mins) Total exposure time 12.5 hours.

The combination worked really well I think.

Hope you like it.
cheers
Martin

Very unsusual rendition but it definitely shows the explosive nature of it. Beautiful field. You must be very pleased how the whole rig performs in that location. Very promising.

I'm going to agree with Marc, it's a most unusual rendition, with the outer envelope looking dusty/smokey, rather than an emission look that seems most common.
The detail is nice to look at with small and tight stars.... Big scopes will do that.
You will no doubt put the wind up the locals when you return as far as the imaging competitions go .although there has been quite an improvement on the local scene since you left,
Must be wonderful to have a scope in such a location, melbourne just doesn't cut it for clear skies, or great seeing for that matter.
Anyway enough blabbing.... Looks good

Definitely an unusual looking M27 but I like it a lot

Cheers

This is the most extraordinary image of M27 I've seen. I love it, absolutely love it.
Thanks Martin.

That is a fantastic image Martin.

The possibilities of that setup and location are tremendous.

OIII wings are so strong and interesting you give the OIII the best show over Ha. Glorious result.

Wow, I'm with Jeanette - it really underlines the explosive nature of the beast and is so "3D". Astounding image. Looks like a new era of amazement on the way as you stretch this new setup.

Thanks for the view Martin, the outer extremities go on ever. It is different, but the faint detail is the best I have ever seen. All the best.

Martin Pugh · #10 31-08-2011, 10:49 PM

Good morning and thanks very much.

You know, if I left the OIII emission line unaltered in the main part of the nebula, all detail would have been lost; it even overwhelms Ha.

So, I backed it off in the main part of the nebula to allow the other wavelengths to bleed through, but in a subtle way.

thanks again!

Cracking NB rendition Martin!
I too love the blend you've come up with (probably the blues

)
I've seen many different results with NB on this target, but I'll have to say, this would have to go down as a favoutite!

I can't get over the wonderful resolution you've achieved with this image. (well I can really... great gear, great location ,in good hands)
Lots of really interesting structure I've never really seen within the bubble. Gives us a bit of an inkling as to how the outer shell was blown off with the demise of the central star..

Simply stunning!!

Fantastic image, and like others have said the colours are unusual but very striking.
It looks like the bright knot in the shell on the right side is casting a long massive shadow out in space, which I guess it probably is. And the central star is so blue! A stunning view, thanks for sharing.
