The hole in the clouds opened in right direction, and it was there long enough for me to finally and positively identify Proxima
.
I even glimsed the red colour, I hope it was not only my imagination.
Very helpul asterism for me to find it was the crescent (indicated in red) with the star rougly in its centre, together with Rob's somewhat distorted Cassiopeia-like asterism.
I attached the chart generated with CdC, and the circle is roughly my 20mm Zeiss Hygens eyepiece, 45' FOV diameter.
Thanks again for your help, guys..
