Details:
Yesterday's transit of Mercury in front of the Sun was almost entirely visible from the Netherlands. The transit started around noon in a perfecly clear blue sky and it stayed that way untill around 6pm, when high clouds slowly came in from the south. Unfortunately I missed the end of the event, but nonetheless I was able to watch everything non stop for hours. And it was absolutely wonderful!
It started with one of the greatest views I ever saw through my 60mm h-Alpha telescope: the tiny planet's black disk just grazing the side of a prominence. While the dot was just making a dent in de solar disk, the rest of the planet's dark side was ghostly visible against the background of a very dim "halo" next to the brightest part of the prominence. An incredible sight!
When the transit proceeded I started making a pastel sketch of the entire Sun's disk. Some small prominences were visible around the edge, and the northern half of the Sun was decorated whith nice filament and mildly active regions. After one hour I finished the drawing with the tiny and inky black dot of Mercury. I photographed the sketch the same evening, and used Photoshop to give it an orange hue and to correct the mirror reversed image. No further alterations were made.
