Hi Marios, is this a sketch?  Looks like a photo!  What techniques and supplies did you use?  Very cool.

I looked at them today at Cagliari between 13.10 and 13.31 with a small achromatic 80/400 (Konus Vista - 80) equipped with a glass solar filter with full aperture at 50X (with a Vixen 8 - 24 zoom eyepiece. not so recent anymore, bought used by a friend). I also used a star diagonal mirror (otherwise you can't get into focus). The observation was conducted in full light. In the photograph I took with my mobile phone of the drawing (putting on the flash) the shadow of the leftmost spot did not come.
