Vast Nebula in Norma

[PhotonCollector]

NGC 6188 Nebula (RCW 108) and NGC 6193 Star Cluster
in Norma.

This is an image I created recently of the vast nebulae complex NGC 6188 in the southern constellation of Norma. The entire nebula covers a massive area of the sky more than 3° wide. The bright star, at top centre, is SAO 227049 (Visual Magnitude 5.6) located near the centre of the star cluster.

Excellent work there. I doubt we would have any chance of seeing that visually in anything but the darkest of inland sites.

Wow! Nice shot, that is very vast! An interesting object.

Great shot there, excellent detail, hey Scott have a go a that one will you with your magic filter just for a comparison.

Nice one Paul,

I've never seen this one imaged before. Looks like an interesting target. What is your FOV? I'm guessing (to lazy to calculate) no more than one degree. Do you think this is the most interesting part of the complex?

One more question. Is the pruple deliberate or is it "just how the camera saw it"?



Thanks

Hi Itchy, thanks for you gratious welcoming comments the other day.

I think the purple (or rather magenta) is the colour of the nebula. If you look at David Malin's partial image of this nebula (A view of the Universe - Pg 90) you will see that the nebula is indeed purple/magenta in colour (same/similar to my image).

And yes this is definitely the brightest part of the nebula. I know that for fact since STAR Atlas:PRO showed me it was the brightest part and I subsequently spent several nights imaging other parts of this very big nebula.

I think we are all conditioned to think that nebulae should be red in colour, since up until just recently only film was used for imaging. Film typically shows Ha/HII regions as red, and so for decades we have seen images of red nebulae.

Yes the FOV in my 'scope with the Canon 300D is 50x33 arc minutes, however the image I posted is cropped and less than that (probably close to 30 arc minutes tall).

That is a very 'Pretty' Neb (if that is an allowable term for us big macho guys to use).

Stunning pic and well captured!

[PhotonCollector]

Thanks.

whether you describe it as pretty, beautiful, awesome, or however, the fact that you looked at the image and liked it as well makes me 'pretty' happy.

My pleasure!
