I only have two or three notes about it, most of them positive ones: - Great data! Never seen so far data from this target as sharp and clean as those files! Love it! - Thank you for posting this video.. We learn a few new tricks and that's awsome and some alternatives in how to process our data. I'll try it also with data that I made from the NGC7000 that I didn't had the opportunity to shoot the SII yet. - In the end and that's the part I've been battle through the years. It's an HOO image as with some channels manipulation to look like an SHO. To be called a SHO image it must have a SII signal. I know that some people say the wavelengh of the Ha and the SII are not to far from each other, but if we analyse Ha and SII the signals are completly different. In this case it's been used monochrome images, but things tend to go worst if using the color CMOS with multiband pass filter that blocks the SII entirely, but the principle is the same as here. I know that many people will want to rip my head off with this comment, but is with the most respectful way that I'm too much BW on this: SHO is SII+Ha+OIII signal, HaOO is Ha+OIII signal, HOHb is Ha+OIII+Hbeta and so on.. In this case, I'm sorry, but is my position.
Hi Craig, Thanks much for sharing your process. I am interested to know if using BlurX in correct only mode before SPCC has proven to be better? I have been running BlurX for both stars and nebula after SPCC and I'm not sure why you split up the task.
That was a suggestion from Russel. He found that running BXT in correct only mode allowed SPCC to identify more stars, so the theory is that it might work better.
Screen blending mode add both color and detail. Color blending mode only affects the color so you won't get much detail. In this case, Screen blending mode retains more of the natural tonal contrast.
Very useful video with a lot of new things for me. Great processing and great data. Thank you very much Craig.
Craig, you give wonderfull tutorials, I love it !!!
Bravo
Thank you for all you do, Craig.
Excellent! I love these Photoshop techniques.

I don’t disagree, and even calling it a "fake Sii" is misleading. It’s really just a way to create a third color in an HOO image, maybe (H-O)OO.
Grazie mille!!! 🤩🤩🤩
great technique, thanks
Amazing,this will save so much time to capture S2.And it will be very good when you have the zwo 5 filterwheel,so you have now rgb and ha-O3
Keep in mind it doesn't actually create Sii data, it just creates a third color channel.
Love your videos but your computer needs to be sped up the waiting times are doing my head in.

on the blending modes in PS, when do you use screen or color. i am a little bit in the dark on this.
Screen blending mode add both color and detail. Color blending mode only affects the color so you won't get much detail. In this case, Screen blending mode retains more of the natural tonal contrast.
