I've just downloaded it and it ran fine, libcfitsio-3.dll is present in imppg-win64.zip. Can you try downloading again, unpacking to a fresh directory and running from there?

On another note: did you copy "imppg.exe" somewhere else (and renamed it "imppg 1.9.exe"?) It has to stay in the same folder as all the other files (DLLs, images etc.). However, it's fine to make a shortcut (link) to imppg.exe (e.g., on the Desktop).

Hi Filip/Great Attractor,

I have used ImPPG 1.9.1-beta or the latest version, and have noticed "Add Mask" option in the unsharp mask section.

Is this enablng mulitple unsharp masks to be applied ?
How do you create the mask on the sun or is it applied to the whole image ?

There is no option for a blend mode or mask layering order or am I missing something ?

Thanks!
Magnus

Yes, multiple unsharp masks can be created. They are applied sequentially; no plans currently for more elaborate blending options etc., but now that you mention it, I'll add "move up/down" buttons.

So far I've been using 2 masks at most; one for sharpening (amount > 1.0), and then one with a much smaller sigma for slight denoising (amount < 1.0).
