IC1396 Elephant Trunk Re-Process Using : 2022-09-11 AIC Adam Block: Color Modifiers in Narrowband Images Talk

[Astrobdlbug]

Everyone,

I watched the Adam Block talk that was released on AIC channel earlier this week that really helped me understand the way 'dynamic' colour pallette mixes can be generated and why, if you have good data in all the Ha, Sii, Oiii channels then this processing technique maximises the captured detail from each channel.

 @TerryMcK posted up his Veil image and a more detailed summary of the processing flow ealier this week and after reading it and seeing the results, I decided to have a crack at using this technique on the narrowband data I captured in August on IC1396.

I will not lie, it took quite a lot of time and experimentation to get to this point as I used stretched images, Adam in his talk demo used linear images, so I had to experiment with the multipliers and the modifier images to avoid saturating various colour hues that generated a less than optimum result !!

Terry  - I used the HO_Modifier and HS_Modifier in this flow.....

I used the Dynamic_HOO mix stars I had processed previously.

Anyway its another way to present narrowband,

 

What do people think of this pallette ?

Wow that is absolutely awesome Bryan. I rewatched the video again to get my head around the modifiers and think I need to practice a bit. 

I love the colours and the Sulphur and Hydrogen are very distinct.

Looks gorgeous to me.  
 

I learnt my foundation processing from an Adam Block DVD but that was with photoshop.  I don’t use Pixinsight.

That's incredible Bryan. I'm usually not a fan of such strong saturation but it works on this target!

I really like the palette Bryan. To me it looks a really strong & deep mix of colours that seem to accentuate the " elephant trunk". I also like the subtle star reduction too.

I've just watched Adam Block's presentation on AIC again and my head hurts on the modifiers. However I understood what he was saying and now need to try it out. He's a very clever guy and his teaching skills are fantastic.

Now playing around with modifiers. I must say that changing the values of the PixelMath calculations is fun - seeing what comes up in the combination of image incorporating the modifiers. All sort of garish colour combinations are possible.

Fabulous. I wonder what the JWST will do with this artefact.      Gary

Fantastic image. Since you asked about the pallete, I like it but think some of the reds in the lower clouds and in the lower part of the trunk itself are a bit too hard edged for my taste. But still a great image.
