My PixInsight Narrowband Workflow - 2022

I thought it was about time that I created a video showing my current PixInsight monochrome workflow (2022). I tend to keep things simple, I just don't have the deep data for anything too fancy.

Really appreciate this video, Paul. Phenomenally helpful.

[@michelemazzola5497]

Thank you so much!!! I will try with my data

Thanks Nelson.

Great video. Will definitely use this.

[@PaulymanAstro]

Thanks Roger.

[@rogerwilkinson2818]

I have recently found your channel, excellent work and clearly explained

[@PaulymanAstro]

Thanks Roger.

[@starsips]

Great work mate! I like your workflow!

[@PaulymanAstro]

Cheers. I like to keep things simple.

[@starsips]

@@PaulymanAstro I completely understand your comments about "no astro for months"... I think it's been nearly 10 months for us in Northern Rivers, with a night or two here and there that have been clear

[@sanddollarastro8017]

Nice video.. you should make a 'how to use GHS' video! Also, can you make your pixelmath expressions available? Thanks.

[@PaulymanAstro]

Thanks. I do have a few videos on how I use GHS. But an updated version using the new process is in the works. I can absolutely look at making my pixelmath expressions available.

[@RigoFromSpain]

Yes i like also the phrase "keep it simple", anyway great workflow, sorry about the six months rain, move to Spain like i did from Belgium, 300 clear nights a year

[@PaulymanAstro]

Wow that would be amazing.

[@krellon]

2 nights imaging in 6 months! Dude, you need to move to the UK, we get atleast 3 nights!! 😂🤣😂🤣

[@PaulymanAstro]

Haha. One day in the future the La Niña cycle will end and we will have our good fortune with clear skies return.

[@josephluciani5531]

Fantastic video, thank you for this. Quick question, how different would it be to apply this workflow to an OSC image?

[@PaulymanAstro]

Thanks. If you mean a OSC narrowband image using a multiband filter, then once you have separated out the channels you could run with it pretty well as if you had done mono. A modern OSC with a multiband filter is pretty awesome.

[@DamianVines]

This is really great Paul :) How could I adapt the expressions if I don't have any Sii data?

[@PaulymanAstro]

Thanks Damian. For just Ha and Oiii I use Ha in the R channel, Oiii in the B channel and then the same G expression as in the video. That’s how I processed the OSC in my latest video as well.

[@yzz9833]

Could you make a video showing how you do this with more than 3 images? I’m curious how you’d map all these filters JWST outputs to the appropriate colour channels.

[@PaulymanAstro]

That sounds like an interesting video idea. I will definitely look into it.

[@schandler52]

Very nice and thorough. However I am just a beginner and have used only photoshop for my narrow band processing. I watched your recent osc rapid video for beginners which was very good. Could you make a beginners narrowband video which goes a bit slower than this one?

[@PaulymanAstro]

I’ll try and organise that.

[@SimjetAU]

Can you do a complete workflow in OSC please using the latest PI ?...I still struggle with PI a lot...BTW I love your videos....6 months of rain...you must be in Qld...we are over up it here

[@PaulymanAstro]

I’ll see what I can do. I know I have some OSC data on my NAS somewhere. I’m in Sydney, we might have a night or two of clear skies this weekend and on new moon no less.

[@SimjetAU]

@@PaulymanAstro We have had only 2 rain free weekends up here since the start of the year....I am over the clouds. Got my first scopes in january and took 5 weeks before I could get a few clear nights. They have been very sporadic since then.

[@travelanddrones]

Excellent video, but could you please make a video about the process to get to the 3 images (Ha, OIII, SII)? I mean how do I put them together? I have 10 Ha images + 8 OIII images + 8 SII images, but since I'm learning how to work with filters, etc, I don't know how to get the final Ha, Oiii and SII images you show in your videos. Thks for your good videos Paul

[@PaulymanAstro]

I can look into that for sure. But to be honest you can’t find a better and more thorough explanation of how to stack your images in PI than Adam Blocks series in WBPP, it’s free on CZcams or you could complete his Fast Track series.

[@travelanddrones]

@@PaulymanAstro thks for your advice. No doubt I'll check that.

[@user-yr2tn8sc1x]

Can the PixMath equations for creating the Luminance be used on Broadband or is just extracting the L channel better for RGB?

[@anata5127]

Have you used Linear fit at the beginning?

[@RyansAstrophotos]

Would something like this be possible with a OSC using L enhance?

[@PaulymanAstro]

Absolutely Ryan. I believe most split the RGB channels and consider the R as mostly Ha and the GB as Oiii. You could then do some dynamic pixelmath to create a faux green channel for nice HOO image or if you wanted an SHO look a faux red channel.
