NGC 3576 The Ibex Nebula

After grabbing the Ha the other day, I managed to collect the SII and OIII on Tuesday night and this is a fairly traditional and original style emission line filter palette, with no RGB.

As mentioned already I had some good seeing for this data collection so that's always good

With those prominent horns of nebulosity that sweep back over the main bright central "head", this nebula has always looked like the head of a magnificent Ibex to me

Capture details are under the image:

Awesome detail Mike, Lovin the colours. Interesting take it's likeness to an Ibex. As Ian says, it looks like she is holding a large fish by the tail. Really nice image mate.

Awesome. As with the H-alpha only version, magnificent contrast in the detail, without it looking over-sharpened. Stars looking beautiful, with proper narrowband colours, and nicely processed.

Soon as I clicked on your terrestrial ibex, saw the horns in the sky.

Brilliant! So much detail and it does not look over sharpened, no signs of worms either

Beautiful image Mike. Those 'Ibex' horns are quite unique.

Very fluo colours. Pretty cool. Surprised you got some details with the seeing of late.

Where are my sunnies??! ........... Aaaah .... that's better!

Seriously, a great image Mike and very striking - excellent! The only nit-pick would be that I'd tone down (desat) the blue / violet at the base of the horns - it's distracting and somewhat out of proportion to the nicely balanced colours in the rest of the image.

Cheers, Marcus

Cheers boy's ...yeeees, it is colourful
This is arguably (close to) the true colour palette for narrowband emission line images - see Richard Crisp's site, the pioneer of "Wavelength Ordered Emission Line" imaging in amateur ranks. Of course, we all interpret this stuff slightly differently too..aaand who knows, I may tweak it some yet

Marcus... that was the bit I liked

Greg, Love One! ...my favourite shirt like that is a bit worn out now too

Hi Mike,

An interesting - unique rendition/interpretation. Sharp.

I am going to have to get my head around the colour though. I have never been a fan of Crispy's stuff.

Cheers,
Tim

Well, it isn't exactly a Crisp palette but certainly more like some of the earlier Hubble palettes than more modern amateur interpretations

Having said that and in the light of day, I think I will give it a tweak when I get home

Mike

Don't change it too much Mike, I think it looks great, it has that neon look about it.

Very striking, Mr Mikey I actually prefer the detail in the Ha but the colour version has an abundance of chutzpah.

Cheers,
Rick.

Ok Bill I didn't do too much, just reduced the magenta bias and electric blue around the tornado in the centre a little

Apart form the contribution form the two other filters in the final SIIHaOIII, when I blink the two Rick there is really no difference in the level of actual details the B&W nature of the Ha does look more contrasty of course

Well, thats a rather awesome rendition Mike, but I cant see a fish, Lol.
Anywho, compared to other images recently, this is not as bright as, quess because of the selected signal you have chose to capture - with that said, your results show up very much betterra the low half of image where them bright spots of nebulosity patches are, & quite interestingly resolved which leave to ponder further on them !
Dig the colour palette also Mike, top show and grouse image

Hi Mike,
another masterpiece.
Great colours & you've even got some of that dark nebula above
that so many imagers don't capture.
Well done.

cheers

I think a lot of people open an image, take a quick look, form a first visual impression and move on, that's it, which is fine of course, t'is a free World...but if you take the time to really look at an image there is often more that comes through. Apart from the pleasing level of details showing as a result of the better than average seeing on hand, what I am most pleased about with this image is that it very clearly shows the varied distribution of the three emission lines. Look around the image for a while and some complex variations become evident, you can see red (SII), Green (Ha) and Blue(OIII) mixing all over the image, there are nuanced OIII blues spread here and there with the Ha and OIII mixing to form a glowing turquoise colour in places, the SII and Ha mix in places to form a lovely mustard green, the Ibex jaw area is completely mixed with the three emissions forming an intricate mosaic of colours. Many other images of this nebula simply don't show this, so while they may look more pleasing to some eyes from an aesthetic stand point, they often don't show the full scene with these three emission lines
