Sunrise at Rainbow Bay

Object Name Sinus Iridium
Object Type Lava plain on the Moon
Location Deventer, the Netherlands
Date April 13, 2011
Media White pastel on black paper

I have made a pastel sketch of one of the features on the Moon which beauty always strikes me whenever it’s visible: Sinus Iridium (Bay of Rainbows). It is a very large feature and always looks very nice in even the smallest telescopes. On that evening of April 13 the Sun’s angle was just right to give the surface that gradient view: dark near Montes Jura with a gradual brightening towards the west. A few rilles were also visible. It was a very pretty sight through my 300mm f/4 truss Dob using a 5mm HR Planetary eyepiece (240x). The sky was a bit hazy while I made the sketch, but the seeing was great.

Kind regards,

Roel Weijenberg
