Finally got round to this one.

Atik 314L over multiple nights. H-A, H-A, SII, OIII

That looks hypnotically 3d very nice.

Crackerjack !

Had to mess a lot with the OIII data (still wasn't enough)... may end up redoing this with 30 minute SII and OIII subs to really get that data in the bag..

H-A channel is nice

[RobH]

Really like the colour the nebula has using this filter combination.

Nice one Nick.

Cheers

Very good pic with an interesting colour combo thats works very well.

[Dave Moulton]

Nick,

I agree with Rob. The works filter combination on this one real well. Fantastic detail that really stands out. Very sharp image, I love it.

It's an unusual colour, but I quite like it Did you use Ha as a lum layer too then Nick?

The SII output of this one is fairly pathetic, even with 30 min subs you get barely a smudge, but it does seem to alter the overall effect nonetheless.

The OIII really starts to come to life with 20 min or greater subs, but still needs lots of them to really give the depth to the lagoony bit in the middle.

Looking forward to seeing more.

Awesome!!!!!

That is so nice and the SII data really changes the object completely...

Really nice Nick!

Thank you so much. I was really unsure on this one, as the OIII was noisy (10 minute subs) and the SII, as said, barely there. I used HA lum and then HA, SII, OII combinations as LRGB in MAxim (varying levels) and then used the hue/saturation adjust in CS2 to get a balance which I found nice..

[Dangerous-Dave]

Just seen this - good work Nick. Original looking colour palette. Yes, Ha certainly overwhelms OIII and - especially - SII.

[narrowbandpaul]

nick, I would try not using Ha as luminance

the ha attenuates the S[iI] and O[iII]

a luminance made from all three channels would be fine however.

you got plenty of data so it should work well

[NickH]

Paul, not a combination I have tried, so thanks for that.

I tried Hubble pallette, and all sorts of variations therein.

Not though of combining all three for Lum.

Many thanks

The narrow bands have picked out the dark nebulosity and bocks globules very nicely. The green halos are a bit distracting

Paul's point about the luminence makes a lot of sense. What was the overall exposure time Nick

[NickH]

the halos are sadly all over the H-A dataset. Around 240 mins of usable subs in total, may attempt to stick some 30 minute OIII and SII ones in to the mix. Ran a 4 hour run of 30 min dark frames yesterday

[NickH]

Seems like the shot (I can now reveal that this was in fact taken with an AX103.... had to keep quiet on that!).... in AN got a bit squiffy (printers issue...not uncommon with newspapers and mags)... but no worries...

[saturn5]

Very unusual but superb.
