Another chicken :)
But I think my first time imaging it. 2nd NB image. Had such drama with this one. It turns out my NB filter set from Antlia contained a blue filter instead of an OIII one. It took me a couple of days to figure it out, and with this weather we're having, that's a lot of lost time!
Anyway, SHO image presented here. Tried layering in RGB stars as I took RGB subs, but I'm not good at that. Something to learn going forward.
268M + Esprit 120. Seeing was terrible, but hey, clear skies!
OIII: 240 seconds x 42
Ha: 240 seconds x 40
SII: 240 seconds x 27 (didn't realise I hadn't hit 40!)
Gain 56, offset 26, High Gain readout mode.
Larger version here (https://adamlawler.smugmug.com/Astrophotography/Deep-Sky-Objects/i-nTQXVHz/A), go have a walkaround and tell me what you think!

Adam,
My goodness only your second Mono NB image , what a cracker !!!
Love the Bok globules just suspended there amongst interstellar space
Mind boggling detail and resolution too, such a clean image
Well done indeed !!!
Any chance of your integration details ?

Hi Martin
Thanks for your kind words! That's lovely encouragement to keep going.
I'm like you; the black globs of this nebula are fantastic. Would love to see a nice close up of this region one day (are you game? :))
Sorry about lack of integration details. I've updated the post now to show this

Beautiful detail Adam. I’m just not sure about the colour. I wonder if it might look more attractive if you move the tint away from so green ? Just a thought.
Cheers

Hi Ryan
Thanks for your comments. You mention something I spent a while considering. When doing the standard LRGB combo, SHO comes through green and that's it's more traditional colour. I actually removed about 80% of the green. When you take too much out, it becomes bi-colour.
That said, I probably will revisit it and do another combination with a different palette, just to see what it's like :)
Thanks again!

That's a terrific NB image. I agree, for only your 2nd NB image you've nailed it.
Greg.

Thanks Pete! Considering the seeing over the first night especially, I'm glad the detail has come through.
haha, cheers JA. Pleased you think so!
Very kind, Greg :) Hope all the struggles are worth it!

Very nice Adam, definitely worth looking at the largest size image there, the Bok/Thackeray Globules look very nicely defined :thumbsup:

This is a great pic !. well done, bodes well for more NB. You have the nack for NB colour mapping early grasshopper :D.

That's a great image. Personally, I like the green in it. The trend these days (and certainly on Astrobin) seems to be a bi-colour orange/blue whereas a gradation from blue/teal to gold/red through a hint of green gives a better sense of the three ionised elements that are being imaged. I think most people think of the Hubble Pillars of Creation image as the prime example of the Hubble palette and it certainly wasn't a binary image (see attached). That is just my opinion though (I'm hoping to start a conversation, not a flame war ;)).

Always, can't really appreciate the quality and beauty of an astro image at a small image size, and as they say, all images look good on yer phone screen ;) :thumbsup:

Ha, thanks Fred. I can't claim credit for that, that's just a simple LRGB combination in PI, and then a little SNR.
Thanks for the comment, Nik!
Cheers, Kevin. Yes I do notice that many SHO images turn out bi-colour. They still look great though! I just wanted to try out something not as common with this image. I know many aren't keen on green, but that's okay :) We all like what we like.
Ha, too true. Small images can hide a multitude of sins :rofl:

Superb image Adam. So much interesting detail. I’d love to learn your star reduction technique one day.

Hi Stéphane,
Thanks for the comment!
To be honest, I just use the EZ Star Reduction option in PixInsight. The EZ Suite is a set of scripts developed by "DarkArchon" and for the most part, covers at least 50% of my workflow. It's a fantastic and easy set of scripts to use:
https://www.cloudynights.com/topic/719344-pixinsight-ez-processing-suite-the-suite-for-your-processing-needs/
That said, it helps shooting narrowband as stars (especially Ha) tend to be smaller anyway. OIII usually has the biggest stars in the range.

Thanks Adam. I did notice the EZ scripts in Pixinsight. Can't say I have yet used any except the live stack which I use mainly for fun during imaging. Thanks for the link.
Nicely done, I am still struggling to get that colour pallette with my NB.

Thanks LKD! What sort of colours are you getting?
Cant seem to get the deep blues and gold hues.

I've found it depends on the target.. e.g. this one I just posted (https://www.iceinspace.com.au/forum/showthread.php?p=1556572#post155657 2) I couldn't get working either, but the gas mix is very different. Hardly any SII at all, compared to Ha and OIII.
