Hi, I’m brand new here and really new to Pixinsight and this script. I’ve been using it with success doing LRGB & SHO. I wasn’t sure what the best way is to combine all 7 of those.
After processing, I’ve done some editing in the extra processing tab going by the video’s advice. However, is there a “brightness” setting somewhere to brighten the image up? It’s probably right there but I don’t see it.
Is OSC processing the same as the others? Just load lights & cal frames and go?
I’m curious as to where to find the graxpert file path to put into autointegrate.
Thank you for reading! I did many searches on these subjects and I’m hitting a wall. I found this group on one of those searches.
Hi, One common way to combine LRGB and SHO is to take stars from the LRGB image and use HSO data for the background (like nebula). Or you can use the H component to create an HLRGB image. Using the Color palette settings in the Settings tab you can mix them any way you like. I am just not sure if many combinations make sense.
There are a couple of ways to brighten the image in the Extra processing tab.
You can use Enhance shadows and Enhance highlights for that.
You can use a Gamma value less than 1.
You can use Adjust channels, set R/K to a value bigger than 1 and check Only K to brighten the image.
I often use the ExponentialTransform option for that.
After brightening it is always useful to try the LocalHistogramEqualization to see if it would make highlights better.
Obviously you can try to make the image more bright from the start by adjusting stretching settings in the Processing 1 tab, or choose a different stretching method in the Settings tab.
Those options are available in AutoIntegrate but one obvious way is to use the CurverTransformation process directly.
Yes, OSC processing works the same way.
You can set the GraXpert path in the Processing 1 tab, and GraXpert settings there. Note that to make it persistent you need to click the small wrench icon in the bottom left corner to save settings.
Thank you. I really appreciate your clarification. My question on the GraXpert is where do I find the path so that I can copy & paste it to put it into the script?
