After another canceled public telescope viewing Friday evening due to thick clouds and light snow, I was pleased to see a nice Saturday filled with sunshine followed by a clear night.
With no particular sketching targets in mind, I scanned the terminator for interesting sketching targets and stopped when I could see sunrise at Ramsden (26 km.) along with all those crisscrossing rimae (rilles).
Northeastward away from Ramsden and across Palus Epidemiarum, I also added two additional ancient craters Mercator (49 km.) and Campanus (49 km.).
This break in our poor Chicagoland spring weather was long overdue.
For this sketch I used: 400 series black Strathmore Artagain paper 9″x 9″, white and black Conte’
pastel pencils , and Conte’crayons, a blending stump, plastic eraser.
