Thx Alan,
i just deleted the IR-RGB image and i replaced with a corrected one.
Unfortunately i noticed that the center of the RED channel was overexposed: "burned".
That defect wasn't noticeable on my iMac while was terrible on the MacBook!
Now i placed a better exposed image with the same name.
About the blank part of Mars: it's true!
I started the animation with some details (with some fantasy they seems two hands on Mars) but the first RGB i took was very blurry.
When i took the second RGB Mars rotated a lot leaving only those small details.
I'm happy about that new (used) optics.
Mars was captured at 13.070 meters focal length.
Remembering the words of Milton, Saturday night i took the chanche to test the collimation on a real star (i did the collimation with the tube in horizontal position) and it was still very very good!
Considering the diameter of Mars that C11 seems to show a fair detail.
Cheers

Very nice movie Alberto and a good long imaging session to see so much rotation.
Every time I get to look at Mars I see the blank parts!!
cheers,
Alan
