Hi Antonio,


Nice work! The LRGB version shows the compromise in resolution that occurs when using an IR luminance to pump up the contrast... the RGB image is sharper.


thanks for posting,

Alan

Hello,
as anticipated I uploaded also the RGB version which may be compared to IR-RGB:

Polar cap is definitely more prominent, as well as bluish haze/clouds on the eastern limb covering Syrtis Major: this renders more faithfully the visual effect perceived at the eyepiece, even though some fine surface detail pops out better in IR.
Thanks for looking!

Antonio
