IC 2177 in HST, sort of ...

[rat156]

IC 2177, the Seagull nebula in Narrowband adjusted HST palette. This shows only the "head" of the seagull (and is pretty much upside down).

Taken over three nights in January 2014, Hydrogen Alpha 5 and a quarter hours, Sulphur II 3 hours and Oxygen III 2 hours.

This object is rich in hydrogen, but there is significant amounts of sulphur as well, there isn't much oxygen, I had trouble teasing the OIII data to get a useable amount of blue into the picture.

The relative amount of H:S has been tweaked a bit to give a pleasing result, or the image would be dominated by the Ha data and be bright green.

You're turning some beautiful images Stuart!:thumbsup:

It's interesting to see the close-up, striking with the Hubble palette.

Cheers,

Justin.

I concur with Justin. Beautiful image Stuart. A really nice 3D feel to the image too. Silky looking data.

Hi Stuart,
A great picture to look at & admire.
Lots of detail & I like the gold colour.

Now that is excellent! Yes, I agree, this gold color in narrowbands is quite attractive.


Very sharp stars, and well processed. :thumbsup:

Hi All,

Thanks for all the positive comments.

Whilst I was playing with the data trying to produce a "super luminance", which I never did get right, I got some interesting results from CCDStack. Here's one that I quite liked, it's more like the highlights of the nebula. Also a starless (almost, there's quite a few artefacts still in the image) version.

Cheers
Stuart

That's a really nice image, great work :)

Love the gold color Stuart, good work. Facebook I dont think will give us high resolution image, even if you uploaded one.

Regards

Nice image, Stuart. I quite like the non-traditional orientation.

That's really sharp and nice Stuart, I prefer the first version.
Maybe its me, but I think I looks better rotated 180.
the areas at 4 O'Clock look like waterfalls.
What scope was this?

Cheers
Alistair

wow, extremely well done Stuart, very smick.

Ahhhhh, Starless! Lovely celestial art! Adding a few bright stars back in would be a classy touch.

[multiweb]

Really like that starless version. The palette really suits the subject. Top shelf stuff. :thumbsup::thumbsup::thumbsup:

Hey, I'm all class, just ask Mike Sidonio!

Funny you should mention that though, at the ed of the imaging run was a 30 second LRGB set of images. Sunrise meant that I didn't get any subs, though next clear night I'll shoot them and plonk them over the starless image, hey presto, LRGB stars and narrowband nebula. Should be quite classy then!

Cheers

Yeah, I really should work on my website a bit more. I've now discovered that Illustrator does web pages as export, might have to have a look into that.



I though way too wide field for you Fred. But thanks anyway.

Cheers
Stuart

There ya go Alistair...

Here's the same image with the LRGB stars placed over the top.
