Astrophotography PixInsight Tutorial - Adding H-Alpha to Galaxies

Hey guys! Sorry for the failed focus, I noticed it when the video was done already...:c
Anyway, here's my first PixInsight video, covering adding H-Alpha to galaxies.
Where I found this method: www.arciereceleste.it/tutorial...
Thank you for watching and clear skies!

Great video man really looking forward to seeing more of your work!

[@CrazedConceptions]

Thank you! :)

[@miketaivalmaa1530]

Thank you .. This has been a challenge for me and you cleared it up ..

[@janeclark1881]

A really interesting video. It's a shame that your image is slightly fuzzy, because I can't quite read the text you typed into Pixel Math. 🙂

[@christianvulpescu1398]

Very cool method! Thank you so much for that tutorial. I did this with other methods but this one is for sure the best one.
I am deepy impressed.

[@CrazedConceptions]

Thank you! I'm glad you liked it.

[@DrewJEvans44]

Such an excellent tutorial for Ha data. Thanks for this!

[@theone4140]

Excellent video, I hope you continue on making more. Very helpful.

[@CrazedConceptions]

Thank you Adam!

[@tullyfisher]

Very helpful and well-explained tutorial. 👍🏼

[@josephluciani5531]

Love this!! I’m relatively new to post processing and although I wish you would elaborate on each step of your tutorial, I will keep rewatching it until it sinks in. Can your technique be used with a OSC camera? I’m looking forward to exploring more of your channel. Can’t wait to try this out come galaxy season this spring.

[@nathanbarnard5997]

Great video! It worked instantly for me. Keep it up

[@lucasmaguire7625]

I'll Take this as an early birthday present haha. you got me excited for galaxy season!

[@CrazedConceptions]

Hehe go get em mate!

[@dalep2842]

Thanks for this! I plan to give this a try!

[@rebulaastrophoto7502]

This is awesome man!

[@CrazedConceptions]

Thanks buddy 💪

[@RaysAstrophotography]

This is great! Awesome work

[@CrazedConceptions]

Thanks man!

[@rudibarani]

Thanks for the great tutorial!

[@Thomas-mn5ih]

Would it not be a good idea, first to do a linear fit on the extracted red and the Ha?

[@abdullahbukhamsin6033]

Thank you so so so much. I have been struggling to add Ha to RGB.

[@CrazedConceptions]

I'm glad I could help you! 😇

[@erni898]

Nice ! i hope we se more from you man, its ice tutorial.

[@chriscausseaux4793]

For some reason when I go to add the HA data in the RGB image it’s not aligning properly… Everything is aligned as confirmed down to a scale of 20:1… I must be doing something wrong in alignment…

[@CrazedConceptions]

That's weird. Did you perform a star alignment before trying to combine them?

[@chriscausseaux4793]

@@CrazedConceptions Yeah... I mucked up the the dynamic alignment due to not paying attention which stars were being selected between the frames... DoH!

[@skywatcher250px]

Excellent tutorial

[@CrazedConceptions]

Thanks!

[@kevinsuhr7707]

Great tutorial 👍. Thx

[@CrazedConceptions]

Thanks man! :)

[@screwyouyoutube5493]

My pixelmath doesn't look anything like yours, so I am lost

[@CrazedConceptions]

Yeah PixInsight updated the look of PixelMath last year, but the functions are still the same. Only now you have the separate channels in tabs instead of below each other.

[@screwyouyoutube5493]

@@CrazedConceptions I figured it out..😂, this was my first day using pixInsight and the learning curve is a little tough, I've have a Mac and loaded DSS in a virtual machine then did all my processing in PS. This is much different and I am hoping to get some better results out of my images. Right now I have 12 hours of Orion with Sii, Oii and Ha, along with LRGB but am having a difficult time trying to find a good tutorial. I will figure it out, eventually, and as long as it keeps raining, I have plenty of time

[@Microtonal_Cats]

Why did I get pink not red, I wonder?

[@dalep2842]

I've tryed this and I keep getting: PixelMath: Processing preview: Alpha->Preview01
*** Error: No such image:
Alpha-Q*(r-med(r))
I have Q=0.1 in my Symbols tab and Alpha-Q*(r-med(r)) in RGB/K tab

[@CrazedConceptions]

Hmm, weird. It suggests that you got a wrong file name of some form... Perhaps the red file is with a large R? Every name has to match for pixelmath

[@dalep2842]

@@CrazedConceptions Thanks for the reply! Ya I went thru everything multiple times and even started from scratch with the formula. I couldn’t get it to work and I didn’t have a response here so I watched Amy Astro and while her formula is much more complex it did work and I was really pleased at how it all turned out.

[@peatkortenjan5676]

did you teach yourself all that?

[@CrazedConceptions]

Well yes but actually no (:

[@wanderingquestions7501]

The H alpha signal is not drowned out. Compared to the white light the h alpha signal is in fact trivial. What you are illustrating is a scientific fake

[@CrazedConceptions]

I'm not quite sure what you mean, honestly. Subtracting the continuum light from the H-Alpha channel is quite literally the most scientific way an average amateur astrophotographer can implement hydrogen data into broadband images...
