Hi all, I've finally managed to take some images of Mercury on september 25.
They have been made with a C14 under poor seeing (but relatively good given
the low altitude).
I've used an IR-pass filter and the RG610 red plus an IRcut, both in order
to try getting an image as "steady" as possible ;-). A manual selection of
around 300 raw frames out of several thousands has been needed, the usual
softwares used for registration were totally unable to process the highly
Frank : the three images seem to show dark markings near terminator : one
south, one north, one in the middle, so maybe we could have hope that they
are real but on this topic I will rely totally on your knowledge of the
planet. The problem is that this C14 may not be correctly collimated.
Best regards to all
