Thanks mate. Welcome back. Foraxx is an interesting one to get your head around but once you have run through it a few times it starts to click and the results are amazing.
Thanks for this I came across the forax PM a while back but my attempts always came out so underwhelming so just left it be. You went the extra mile for me here and gave a good explanation of how to do it. Will be putting this to work later. Thanks again 👌🏻
Thanks Luke. It is a pretty cool idea once you start playing with it. You can even start to play with the palettes within the formulas and get adventurous.
@@PaulymanAstro it is indeed, and your HOO pallet looks amazing. I always seem to get light reds and blues where as yours has nice dark shades. I really need to figure what im doing wrong, do you reckon its my filter (L-eNhance)?
This is fascinating, a real improvement on a standard RGB result. Thank you very much for sharing this, I will be adopting this method for trials on my current project. Cheers.
Thanks mate. It is an awesome idea once you get your head around it. I’ve started playing with other dynamic factors and blending some of my other favourite palettes like OHS and HSO.
@@PaulymanAstro It would be great if you could also show us with the OHS and HSO palettes, but not in 5 minutes!🤣 I would like it to be very detailed so that we can understand what we are doing. Thank you very much for this great video!
The beginners PixInsight series is terrific. These clear, well paced, short videos are an ideal way to learn this complex program. Photometric Color Calibration has been recently replaced with Spectrophotometric Color Calibration and a video on this process would be very helpful. Finally, additional short videos on other frequently used PixInsight processes would be greatly appreciated.😊
Thanks for watching Victor. SPCC is definitely on the cards. I have some 5 minute Friday videos on the processes I use the most frequently but aim to expand that into 2023 to cover some others.
@@PaulymanAstro The Friday videos are what I was looking for and I look forward to the video on SPCC. Here are a few things I’ve run into: If SPCC gives you an error message: 1. Increase the Saturation Threshold under Signal Evaluation. 2. Go back and perform Plate Solution and SPCC on uncropped images to get more stars 3. Decrease Minimum detection SNR from 0.40 to 0.10 The SPCC graphs I’ve generated so far are scattergrams, not the nice tight bands of dots that follow the plotted line that I got with the old PCC, and the images generated occasionally have unusual colors.
Really interesting tutorial on this method. I have an image that I am struggling to get a pleasing result from with regards to the palette so I think I will give this method a try to see how it comes out.
Thanks Greg. I never really got much out of straight Forax either since it just looked like HOO. It wasn’t until I started really looking at where it was diverging and then playing with the dynamic factor images that I started to think wow this is really something cool.
Thanks Pauly for your great YT videos. Your work is excellent. I just tried your Forax script in Pixinsight and greatly appreciate all the hard work you have put into it. I very much like the result of the dual band HOO Jellyfish Neb I just finished precessing. Do you think there could also be other color mapping combos in the future? That would be really cool and unique. Thanks again!
Thanks James. Glad you like the script. A simple way to try other Dynamic palettes would be to just add your channels to the script in different orders and see if it produces something you like.
Sure. The expression for 2 channels is easier. You need to create the ho image as I did in the tutorial first. Then the expressions are: R: Ha G: ho*Ha+~ho*Oiii B: Oiii I have also now created a script that will do much of the work for you. I have a video that links to the repository for the script.
From what I’ve seen Siril looks great. Happy to see GHS is now available and I did see they are including some PixelMath so that’s awesome. In terms of the pixelmath expressions above then, I’m not sure how plug and play they are for Siril. The tilde represents “not” if there isn’t an equivalent in Siril you can use (1-ho) in place of ~ho.
Possible to do this in gimp? I know you can combine mono channels to make a color image, but compared to pixinsight all you could do in gimp is visually adjust various layers to certain brightness and contrast, then combine and still pixinsight seems way more rewarding.
I’m sure it would be possible using luminosity masks and their inverses. But this method does really highlight the power of pixelmath inside PixInsight.
Man I take a six month break from burnout, and I have to relearn all these Pixinsight techniques!
Well done
Thanks mate. Welcome back. Foraxx is an interesting one to get your head around but once you have run through it a few times it starts to click and the results are amazing.
It's great to see someone explaining some of the PixelMath ideas.
Thanks Stephen.
It's quite a piece of work I must say! Thanks for makign this video, it's the clearest i've seen so far on the Forax palette. Keep them videos coming!
Thanks very much!

Thank you so much Paulyman for this video. Absolutely fascinating. You are a talented teacher with a very clear method of explaining technical tasks.
Thanks Rick. You’ve made my day.
Great explanation. I've used the ForaxX palette before but have not really understood what was going on enough to improve it.

Another great video! Cheers Pauly!
Thanks mate.
nice job, i'll have to try this on my next sho. i love the blend, best of both worlds. I never cared much for straight Forax.
Thanks Greg. I never really got much out of straight Forax either since it just looked like HOO. It wasn’t until I started really looking at where it was diverging and then playing with the dynamic factor images that I started to think wow this is really something cool.
Can’t wait to try this!
I am in the process of making a script to automate some of the steps in this video. So keep an eye out for its release.
Excellent work! I'm lovin 'it!
Thanks Adriana.
Perfect explanation of Math. THX :)
thanks for this video, I like the yellow green "backlight" it provides :-)
Thanks. I saw your latest image using the palette on Insta, looks great.
@@PaulymanAstro thanks, following this video made it easier for sure. 👍

Love your videos - thanks for sharing
Thanks John.
Thanks for this tutorial. Can you add Pixelmath expression when using only Ha and Oiii images.
Sure. The expression for 2 channels is easier. You need to create the ho image as I did in the tutorial first. Then the expressions are:
R: Ha
G: ho*Ha+~ho*Oiii
B: Oiii
I have also now created a script that will do much of the work for you. I have a video that links to the repository for the script.
@@PaulymanAstro thanks. I do not use Pixinsight but open source SIRIL including only pixelmath.
From what I’ve seen Siril looks great. Happy to see GHS is now available and I did see they are including some PixelMath so that’s awesome. In terms of the pixelmath expressions above then, I’m not sure how plug and play they are for Siril. The tilde represents “not” if there isn’t an equivalent in Siril you can use (1-ho) in place of ~ho.
@@PaulymanAstro All the expressions are identical... As I can understand pixelmath seems to come from opensource...
Possible to do this in gimp?
I know you can combine mono channels to make a color image, but compared to pixinsight all you could do in gimp is visually adjust various layers to certain brightness and contrast, then combine and still pixinsight seems way more rewarding.
I’m sure it would be possible using luminosity masks and their inverses. But this method does really highlight the power of pixelmath inside PixInsight.
Will you release an update that works with the latest PixInsight version 1.8.9-2?
I have updated the repository in the past week or so, so hopefully it should update automatically.
awesome
Thanks Dan.
why "forax"?
That is the social handle of the guy who first published the pixelmath expressions.
o1*sii+~o1*ha
ho1*ha+~ho1*oiii
(ignore, its just so I can copy paste it whenever I come back to this video)
