A PixInsight processing tutorial to get the blue to pop in your HOO or Dual narrowband images! You first need to have aligned and calibrated H and O frames (from dual narrowband this can be done by Channel Extraction, then R is H, and (B+2*G)/3 or max(B,G) is O)

Outstanding video. I had never seen the EZ process scripts so that was a big help. A lot of these tools I have used before but this workflow seems to have gone better than my usual! I still opted to process the HOO and a Lum separate to combine later. Mostly because even with 15 hours of O3 (NGC 7822) it was still pretty noisy.

In this processing of the blue work flow I’m impressed. Being sorta retired I can spend hours and hours in pixinsight. I’ve watched all the osc color sho videos for pixinsight and Astro pixel processor. I believe I have found the one , like the one video with practice I can master it. I use the L extreme filter . I have been thinking about the $2000 plus equipment set up for narrowband . I mean I just bought the Stellarvue avx 102t so why not. But then I told myself wait and see what processing advancements come up. You did it thank you. I might have to watch it 50 times but I’ll get it.

That’s yet another great video, Cuiv! Great to see how you bring those blue’s forward and nice how you used DBE to get rid of the introduced artifacts. Usually I do DBE at the beginning and never touch it again, but for these situations it can work very well. It’s of course a matter of taste, but as much as I try, I can never really appreciate the results of TopazDenoise. It tends to make the image a bit plasticky/artificial. Hope your scopes will be back in operation soon!

On another issue, I recently got the pedestal problem with some of my images as your OIII. I solved it more or less by adding a pedestal value in WBPP but I can't figure out how I got the problem in the first place and why it affects some of my acquisition but not others.

First seen this method by me! Supercool! Thank you for the great instruction. For the unperfect edges in the range mask I would use CloneStamp in the mask ( eventually in combination with an Adam Block - black "color bucket" to pic the pure black from). I mean the trick if you drag a clone and put a value of 0 in Pixelmath on the clone. Than you have pure black as reference point for Clone Stamp. Greetings and Clear Skies, Christian

Thanks Cuiv, very helpful. Hey I know it is off topic but may I ask how do you review your subs before stacking? Is there a particular software you use to quickly review and weed out the bad ones? I started with my Canon DSLR and was using Backyard EOS which made it so easy to page through all the subs and delete bad ones. I'm working with a ASI294MC and NINA now and not sure of the best way to review the fits files. I'm trusting DSS and taking a low percent. ;o)

Hi Gary! Well on the Rosette, at least from here in Tokyo, I'd for for HOO first, then maybe add SII later! Probably completely ignoring LRGB. Number of subs completely depends on your conditions and how you see your SNR evolving, so I can't help there. I'd probably shoot to have twice as much OIII as Ha, as the Ha can get a great SNR very quickly. Good luck and clear skies!

When I do RGB/OSC shots, I stick to reality using Photometric Color Calibration. For narrowband you stick to reality, but not to what human eyes can detect. You map relevant physical bandpasses to different colors, and how you do that is completely up to you. Hubble nebulae pictures typically use that same technique. It is physically correct and appropriate, but since there is no RGB reference dictated by our eyes, there is a lot of freedom in processing.

@@CuivTheLazyGeek where I see disadvantages, I see growth and opportunity for growth. I think being confined to such bright white zone, we have had to attempt and improve our processing skills. I don't mind my bortle 9 skies anymore. Your work is great as always! Keep it up buddy! 🙂

One note: When using ABE and DBE you should choose the correction algorithm based on what you are trying to correct. Sky gradients are an "additive" component to the image (since every pixel collects " N " photons from the nebula + " M " photons form light pollution), while vignetting is a "multiplicative" component (every pixel collects " N*L " photons, where N is the number of photons emitted by the nebula and L is a scaling factor telling us how much of those photons actually reach the sensor. In the middle of the image L is 1, at the corners it might be 0.7 due to vignetting "catching" 30% of the light incoming). You should use "subtraction" for sky gradients, and "division" for vignetting. I hope my comment makes sense 😅

Your comment absolutely makes sense! A long time ago I was doing this religiously (and yes I tried division when preparing the video) but for the life of me I've never see division doing better than subtraction... I know in theory it should for vignetting but...

In PixInsight you have the ChannelExtraction process, or a button top-left that does that. You could also use the new WBPP channel separation feature.

Cuiv!!!!...What Did you do to your Rigs?......Out of Commission!!!!....LOL........Great Tutorial. I don't use PixInsight.....Yet....LOL......But its good to see how it works when I do. I primarily use Linux ( I'm a Programmer, and Technologist) so most of my processing is done Open Source.... But, I finally built a Windows Laptop for Imaging, Guiding and Editing..Just to make life easier...Ill Buy PixInsight soon... Look forward to the Next video....

Pixinsight does run on Linux by the way! So that will be fine! It actually runs better on Linux than on Windows!

Quiv! You will benefit greatly with the newer Topaz... I had ver. 3.0.3 (which has 'Low Light') and works quite well. But the latest version handles noise much better. Like it's learning or something :P! Anyway the differences are quite profound..

AI Clear is there. Same thing just labeled 'Clear'. There should be 5 options to choose from. Standard, Clear, Low Light, Severe Noise and RAW.
