Great video with loads of tips and tricks (apart from the colour bit). Getting rid of those really small stars by making them fuzzy is great....I have been trying to do that on my images recently, but without much success - I was using curves to try make them vanish, but putting the out of focus is great.
Hello! Congratulations for your amazing work! Any video about adding a colorized Ha into a RGB image? Or we just have to colorize the Ha like in this video and then add it to RGB using PixelMath?
Could you comment on one item that I do not quite understand about Pixelmath. You are adding the Ha and O3 images that have been converted to RGB to the individual R, G and B channels in Pixinsight. I would have assumed that one adds by definition a grayscale image to the individual channels. (e.g. what happens to the blue component of your Ha when you add it in Pixelmath to the Red channel).
Is there any reason why you do division instead of subtraction for background extraction? I always thought that flats correction was division and background. Subtraction or gradient was subtraction
Hell yeah brotherman. Just a tip to save time, use ABE with function degree set to 1 or 2 and it will get rid of those fairly simple gradients ez pz. (I know.. I used to hate ABE too)
Hi one question. I searched your videos HOO. I photographed in 2022 the Veil Nebula with the Extreme filter. This year 2023 with Triband Ultra RGB Antlia filter. But I would like to accentuate the red and blue colors, extracting Ha and O3 from the 2022 data with APP. I found a formula for HaRGB online, even though I don't like it much. Do you know any formula for adding Ha and O3 to the 2023 data?
Ulitmately all you're really doing there is changing the result so that the green channel contains very little information as when taking the two RGB images into the Green expression, the green channel contains very little data as you made them mostly red and blue. It would be useful to see a comparison where you do the first combination using the grey scale images, but set the G channel to zero as thats closer to what you're doing in the final version.
Great Video!!! Do you have any idea how i might get star x termanator to speed up? I have a reasonably fast laptop and its still 13 minutes an image to remove stars. If i do batch processing on this thats 26 minutes. Thanks
hello, i tried this technique again and found that its really hard for me to create the balance of the chanels that is not overly saturated. Any advise on how "diluted" the colours should be?
I'm finding that when I precolor each master image that I need to color without adding any saturation or c component vibrance boost. For some reason when they are combined in pixelmath the saturation gets enhanced. Try pulling back on the presaturation.

Oh hell yeah!
Hell Yeah! Late to the party, but that's good stuff... Thanks for sharing!
I can tell you’re quite proud of this one. Hell yeah man. One of the best!
Hell yeah, brother! Another great tutorial! I appreciate how you always give such great tips and explanations. Thanks!
Thanks man!!!
Hell Yeeeahhh!!!! Your tutorials are incredible and the help you have given me is very much appreciated. Keep the great content coming.
Will do....thanks!!

Woot, Woot!!
Squiggly line symbol is called Tilde. ~~~~~~~~~~ Yet another very comprehensive tutorial by the way!!
Ah...but when do you use it? Lol
@@enteringintospace4685 when ever you feel included to do so!!😆
Inclined!!!!! Not included, stupid auto connect!!!!! 🙃😁
Awesome tutorial. I will try on my Veil Nebula tonight...thanks for that Steve'O
If anyone goes too fast on RUclips just slow the speed down to 75% . Try it it works. Every RUclipsr should tell their audience this.
Hell Yeah! beautiful process
Thanks!
Nice!!! 👍🏻
Ooooh! Dat is Nishe!!

Hey sorry for late response. I've definitely done some Colorized hargb images but haven't done a video on that process. But for you I will 😊

PixelMeth can never be simple lol (*.02)+j/k(oii~.4). great work and thanks again!!!
Right on!!

Would you have used GHS to stretch the H and O if you were to do it again?
Hell yeah brotherman. Just a tip to save time, use ABE with function degree set to 1 or 2 and it will get rid of those fairly simple gradients ez pz.
(I know.. I used to hate ABE too)
Lol...I still use it but there are time when it seems to invert the gradients. Plus...if it doesn't hurt its not worth it 😄😄
hell yeah :D
How many hours and what gear?

Hey sorry for the late response Facebook notifications stink.
I should have a video out soon doing just that! Stay tuned..

Get a desktop computer with a NVIDIA GPU, StarX supports GPU acceleration.
Thanks! I tried the Cuda core upgrade but then read where that didn't make a difference with star x.
For now it remains worth the wait.

Bam!
The ~ tilde symbol in regular expressions inverts the value (in pixelmath the value of the pixels), so ~x = 1-x
¯\_(ツ)_/¯
Thanks for sheading the light 👊
Great tutorial very thorough as to the process. However, personally I could do without the childish interjections.
