Does imageblend appear in your PixiInsight/src/scripts/CosmicPhotons directory? If so you can probably add it using the Feature Scripts facility. If not then you can use Reset Updates to force a reload of everything in your repository list.

One technique you could try is to use clone stamp on the stars only image to remove the thin streams of nebulosity from that image. You can then form a new starless image by subtracting your clone stamp edited stars image from the original image. I …

For a, ie Green/Red, the "magic" numbers are 0.35 and 0.65. For b, ie Blue/Yellow, the "magic" numbers are 0.13 and 0.87.

It is not quite true to say: "The Bill Blanshan method is not really star reduction per se. It is a modification of the MTF (brightness) of the image on a star layer before screening back into a starless image." The script that Bill and I produced, …

Hi Jeff This is an issue I have been aware of - you have done an excellent analysis here so I will give you a thorough response - sorry if it is too much information! Let's start by analysing how Background Neutralisation (BGN) works. At a high leve…

The Initial State is a process container containing all the processes that were in the history of the image from which you made the clone. Double click the Initial State to open the process container and you will see all the constituent processes.

Hi Adam No problem! I see you have already updated your ColorMask script page - thanks! The link you have on that page is now pointing to the process but, of course, your video relates to the script version. It may be worth a few words to explain th…

The colour mask script has now been upgraded to a process which you can download using the following repository: https://www.cosmicphotons.com/pi-modules/colourmask/ (note the British spelling of colour!) The process improves on the script primarily…

The work around to create a new image is to clone the original image first, then apply the mask to the clone and then apply PixelMath/ScreenStars to the clone.

I am sure that Adam will have his own wisdom on this but let me throw in my 2d-worth! For standard SHO you would place S in the red channel, H in green and O in blue. The equivalent in NBCM is to add a layer with S set to hue = 0, saturation = 1; a …

I think you would need to use CloneStamp for this. But if you are clone stamping over nebulosity you will inevitably be creating stuff that isn't really there! So proceed with caution and use only where really necessary. If you are planning to repla…

I have placed an Image Solver instance .xpsm file in dropbox here. This works fine for me.CS, Mike

I think they may have quoted the FL with the reducer in place.

The Takahashi FSQ-106EDX has a focal length of 530mm so with the 0.73 focal reducer we have 387mm. If you use this in ImageSolver your image solves fine.

Hi Vic I have italicised quotes from your post below and added my comments. I hope these help. Selecting Clip mimics Arcsinh's unticked "Protect highlights" setting - That is correct. Stretching a starless image does not require RGBBlend - Usually …

Hi Victor That's a lot of work, thanks for sharing! In the GHS section you say you have not been able to get the Colour setting to work. May I offer a few words to help with this? The Colour option preserves colour in exactly the same way as the Arc…

Hi Reggie Bill Blanchan and I have launched a PixInsight process designed for solar image processing. You can check it out at Bill's YouTube channel. CS, Mike

Version 2.1 now released allowing overwriting of existing files.CS, Mike

The beta script should still be available from that repository. Have you previously successfully downloaded it? If so it looks like PixInsight has lost it somehow which does occasionally happen. I suggest in this case using the Reset Updates facilit…

Hi Ron So, when you run SXT on a starry image the first thing that happens is you generate a starless version of that image. Then, if you tick the "Generate Star Image" box, you are asking SXT to use the starry and starless images to generate an ima…
