Nick, Of all the times to be comprehensive... lol. When someone presents an issue to me they rarely post a single screencapture.However, in your case the answer is found in the *first* warning of the console. "No valid PSF signals.... " So Nick... w…

Yes, it is very much over the top on my monitor to compensate. There isn't another great way. There is a very complicated way in which you force your monitor to be calibrated and then display images based on their monitors... way to much work I thin…
-
I do not know what you were told.Printing to metal is a difficult challenge. My approach has been to figure out a compensation adjustment you need to make in both brightness and color that will make the image look *horrible* on your monitor...but it…

No...that isn't how the astrometric solution works. I don't think you are using the right tool.You should be Aligning By Coordinates (in scripts). PixInsight should be able to interpret the existing astrometic solution that is provided in the HST da…

No. Applying flats is supposed to always help. I do not have workflows where you do not do helpful things. :) -the Blockhead

I don't think this is a light leak per se... it might be scattered light caused by the baffle (or an adapter). I would work on finding the source. Unfortunately, in my opinion, there aren't great solutions for getting rid of this. You can force Grad…

There is definitely something in the light path causing that scatter. There may need to be an edge of the optic or something that needs to be blackened.-the Blockhead

Yes The substitute script (the one *I* helped make) in combination with a mask (GAME) will blend seamlessly. TDE is turned down edge (a common malady of reflectors). -the BLockhead

I have a guess... you didn't give me this information though.A globular cluster has stars that range in brightness from saturated all the way to the faintest detected signal in your image. My guess is that you used BXT. Do you see the issue? There i…

Ok. Thanks!-the Blockhead

That technique, if it is the HDRMT bit, is now available as a single click in HDRMT. The intensity checkbox does this work for us now. But having seen what is happening..you now know how it works. -the Blockhead

You need to say what telescope you are using.If there is an asymmetric artifact as shown here..it should be connected to something in the light path at the front of the telescope. For reflectors this is often a cable that is sticking out from a seco…

Hi Roger, 4. I guess the confusing part of the question for me is the fact I do not think there is a difference. When you give SFS a color image...I think it is analyzing the three channels individually. So the results should be the same as giving S…

Indeed...I was going to say... what the $%^! are you talking about. (And did you see *my* old image of the same? (https://www.astrobin.com/g4oe2p/?nc=&nce=) -the Blockhead

Ha!

Hi Roger, 1. Maximum quality is the default. Really though, these are just presets for the number of things you turn off in WBPP to speed things up. These presets came before Fastintegration. If you are concerned about anything other than Maximum Qu…

Yes, I agree. You will get some saturation of the stars... but I think that is OK. I am a "nebulist" . Some people care more for the stars over the deep sky object itself and this has always puzzled me since it isn't the main subject. -the Blockhead
-
There is a constraint. I am tasked not only to show what I do...but also find workflows that are reproducible. The steps I show you get you to a consistent place and from there you can launch into other realms.You said: "SelectiveColorCorrection - I…

Let me add that I show how to use ImageBlend in many ways- quite a few examples in NB FastTrack.ImageBlend is the key to doing the job of what you want in PixInsight.-the Blockhead

At the moment the best videos that demonstrate the idea are these two: https://www.adamblockstudios.com/articles/continuum-subtraction-using-nb-colourmapper-scriptandhttps://www.adamblockstudios.com/articles/blending-halpha-using-nb-colourmapper-aft…
