Thanks for watching the video! Feel free to ask anything related to astrophotography, NINA, or PixInsight!

Great tutorial, subbed

[@SPACEJUNKastro]

Thank you!🙏

[@waldemarwitt764]

Thank you. Very informative! I subscribe to your channel. Slowly feed the material and it will be great!

[@SPACEJUNKastro]

Thank you, much appreciated!

Do you see any advantage to the NBColormapper method over Bill's Ha to RGB advanced method in galaxy mode? NBColor looks much more complicated, but I've struggled some to get good results from the Bill's script too.

[@SPACEJUNKastro]

I’ve used Bills PixelMath for some time but it’s always been hit and miss. With NBcolor mapper I have much greater control over the whole process and I can produce an acceptable result every time. It’s definitely worth to take some time and learn how to use it.

[@Jcastleinfo]

@@SPACEJUNKastro Thanks! It's good to know the hit-and-miss result was maybe not just me. I will give this method a try over the holidays. I have about 50hrs of M33 just waiting for me to spend a day on it.

[@SPACEJUNKastro]

That’s quite some time! Good luck with that. Clear skies.

Do you have a beginner video? I've been using APP for 5 years now but want to switch up PI.

[@SPACEJUNKastro]

Check out the playlist, you can find a couple of videos covering the basics in PixInsight with free data to download and follow along with the video.

I really like your videos car you simply do what it's need; no empty chatting, just contents. You go fast? Maybe it's true but these are not contents for newbies of pixinsight. But, man, please, stop with this horrorific background music!!! A nice silence is better. Please.

[@SPACEJUNKastro]

Thanks man. I try to improve something every time I publish. Will consider your suggestion. And finally I agree - it’s not something for complete beginners, so I assume the audience has basic knowledge. I have other videos pointed more for beginners that contain “empty chatting” 🤣

Oh boy! 1. Way too fast delivery. Most people who would watch this video would not keep up. 2. The script you reference is frankly broken! There is a better pixel math way to do this. 3. Over doing the inclusion of Ha and Oiii into rgb images can be a big negative (i'm guilt of this!) 4. One has to be very careful with GraXpert because the AI version is not so good, manual mode is I think better if not too much nebulosity, else DBE still rocks as less signal loss in critical areas. Overall result B+. I've subscribed becuase I think you are smart and will get better at this, more critical thinking perhaps! Oh, in just in case you missed it, slow down!

[@SPACEJUNKastro]

Thank for the critique, much appreciated! 1. Agreed! Will consider on next video. 2. The script is genius, not broken! I am aware of bills pixelmaths if that’s what you are referring to, but I get consistently better results with NBColourMapper. 3. Use with caution! 4. Agreed! Check out my other video where I talk about GradXpert and oversubtraction. And finally agreed, DBE is the way to go. Thank for B+, will improve.

@@SPACEJUNKastro fwiw, I just did my first try at combining narrowband with broadband, and I liked this approach vs the Bill Blanshan script because my narrowband is from an L-Ult and I wanted to bring out the OIII nebulae as well. While it's not mentioned in this video, I followed pretty much the same process with the extracted OIII data and got a pretty decent result. Definitely need more integration on the nb data though. Afaik the Blanshan scripts don't support bringing the OIII in too right?

[@SPACEJUNKastro]

I tried it multiple times with Bills PixelMaths even with OIII signal. It can be done, but not once I got results like using NBcolourMapper.

[@pcboreland1]

@@SPACEJUNKastro I've used this script, and I do think it has issues that will I'm sure will get fixed, regardless try using something along these lines, it is kinda the same thing but I feel easier to manage: R - med(r) + 0.4*r, where r is the narrowband image red channel for say Ha. Same formula used for both the green and blue channels for Oiii. You have to play with the scaling factor.

[@KurtFB-r6x]

For me this is an interesting method and as others have mentioned, you could slow down some. If you could do another follow up video taking more time on each step (not a lot of time because I’ll probably stop and start the video many times until I learn this technique). Just subscribed.
