Hi mate. Ive played around with duo band channels and tbh I can get the same (any) result with simple colour balance on the original image. Also it makes no sense to use green as the O3. If you look at sensor profiles..Yes, it has more signal than blue but it also has h alpha in it -as much as 1/5 of the red. Blue pixels are more specific to 03 as it has almost zero red sensitivity.

[@lukomatico]

Hey mate! - That's awesome if you've got an alternative better method to this, I will say this is an old video now by internet standards and my newer versions give far better end results though, might be worth checking out if you are on the hunt for some techniques! Cheers!

Can you please tell me why, what should I have done?

[@lukomatico]

Hey Ulf! - Assuming your PixInsight is fully up-to-date then it sounds like you did everything correctly, the next restart of PixInsight should have finished the install for you :-( It may be worth checking your current version against the latest download on the PixInsight website as the auto-update feature only works per-release for incrementals.

Thanks for the great tutorial, but one question, Is this procedure just as good as using something like Astro Pixel and doing the Ha extract and O3 extract and combining the images in App first? (For lenhance)

[@lukomatico]

Hey mate! - I'm afraid I'm unable to offer an opinion on that as I don't have APP! :-) There are certainly many routes to a similar end result, and I know APP is a good program so it wouldn't surprise me if it worked really well! - I'd just personally not know how to go about creating the synthetic 60/40 weighted channel in other programs without PixelMath! Thanks for your comment mate :-) Clear skies!

What did you use to stack the subs?

[@lukomatico]

Hey there! In this video I'll have used WBPP in pixinsight to stack :-) hope that helps!

[@alexandrefagundes7233]

Hey dude, thanks for your sharing. So, I have a question: when I try to apply the BackgroundNeutralization in my image, it's impossible to continue cause the process needs a Preview. How you can do this process without a preview of the background? Tks again for your sharing!

[@lukomatico]

Hey Alexandre! That's not a problem I've experienced I'm afraid, are you opening the tool and dragging the triangular process icon over the intended image, or selecting to run it without a target? That could be the issue :-) If you need a preview however, then alt+n will allow you to draw a preview box for the background which should allow you to proceed! Hope that helps!

[@lukomatico]

Hi luk. Can I ask you a question? Why did you use morphological transformation in the star mask of starnet ++? If you do "starless + star mask" and then morphological transformation, isn't that the same thing? Sorry for my English. I do not speak very well. I'm italian. Thanks

[@lukomatico]

Hey Salvo! - your English is great mate, much better than my Italian for sure! :-D I apply morphology to the stars separately to avoid it being applied to bright sections of nebulae also which can sometimes happen when used without a mask :-) I hope that explains my reasoning, thanks for watching and commenting my friend! 👍👍

Great video. Just had a go using my Heart and Soul Nebula data. Looks ok but how can extract more yellow?

[@lukomatico]

Hi Paul, I'm glad you've had a go at your data with it :) - to get more yellow I'd be tempted to either alter the pixelmath blended green weights, or instead use your curves in the green + red channels after recombination to raise those levels a bit which naturally would make more yellow :) While practicing this technique I just tried loads of variations of the above until I was finding results closer to what I wanted, It took me a while but you eventually start to get the feel for it. I hope that helps mate!

[@paulradford6902]

@@lukomatico I might try blending different amounts in Pixel Math. I tried the curves in all the colours but just couldn't extract the yellow that I wanted. Thanks for the advice Luke.

I got to Starnet point. When I open StarNet, there is no RGB and grayscale weights files. It suggests to select them. What files are they? After EZ Denoise and EZ Soft Stretch, I have saved files as .xist format. StarNet files are .pb Please elaborate about these files for StarNet. Do you create them? Thanks

[@lukomatico]

Hey Ana, if you click the little wrench/spanner icon then the weights files should be in your pixinsight install folder natively if it's a fairly recent version 👍 Hope that helps!

[@anata5127]

@@lukomatico I tried it did not work. But, I installed StarNet v2. Really easy to operate and quiet different from original StarNet. Overall, I run from beginning to end your method. Worked extremely well on Laguna Nebula!!! I used just L filter. It was my first guided (30 sec) image on rebuild from scratch (I.e. totally ruined) AVX mount. It was also first multi day photo (5h overall). Image was actually 6.5h, but I applied strength selection, and many subs did not pass quality control. Step-by-step moving towards full automation. I guess I will need couple of more month to be there.

[@anata5127]

@@lukomatico Yes, but I have a lot of problems with mounts and manufacturers of these mount. They are just well off specifications. What mount do you have and what is tracking and guiding accuracy?

[@lukomatico]

Hey Ana! I use a skywatcher eq8 and skywatcher eq6, - my samples of both mounts are capable of guiding around 0.6 arcsec in average conditions, down to 0.4 or so in superb seeing conditions 👍 - I have been very lucky with them both though!! Mounts can be a bit of a lottery sometimes, the only way to really guarantee you get a great one is to either buy used from a seller who can prove it's performance, or buy new and look at higher end mounts, perhaps even with encoders. Hope that helps! :-)

[@Yetithruhikes]

Important to emphasize that this is creating a Hubble COLOR palette and not a Hubble SHO image.

[@lukomatico]

Hey there! - thanks for your comment :-) I believe I did mention a few times in the video that it's a 'hubble-style' palette, and also that the SII channel is synthetic when creating it 👍
