Thanks to everyone for the nice words
Here's a new image of today with clear sky, windy and a good seeing (not exclellent but enough by my Sauron 14").
About the colors: I tested so many kind of curve with PS2 and at least I founded the right that doesn't appear too yellow and not so red.
I use PS2 to finalize the images, so the final unsharped image obtaind with Iris is passed to PS2 via .fit and then I convert in RGB16bit, add the colorizing curve (I named it Halfa by similarity) and then I finalize the image with some other little UM or gauss.
Cheers and good sky, Anto
