Hi all,

On Dec. 28th I met my friend Nicola and we had a session on Mars with
his own Orion 250mm newtonian featuring optics which left something to
be desired.

Seeing mainly poor with a fair window lasted enough to grab the 3 RGB
streams. The small image scale allowed a fast exposure (1/30th sec.) and
a low noise (less than 10dB) to better freeze the turbulence. The Iris
drizzle (2X) worked beatifully indeed! I didn’t expect such a result!

But as always happens, the boring side is facing me whenever I grab Mars
under acceptable conditions. So, the B image is much more interesting
than R, you can see there the 3 lined up orographic clouds over
vulcanoes and the isolated Olympus cloud on the right.
Also, notice the completely dissolved NPH making the thiny NP with its
dark collar popping up nicely.
