It has been more than a year(!) since my last lunar sketch, but yesterday I dragged my 3" f/16 Unitron/Polarex outside for some good old sketching.

The most prominent feature on the surface was a line of large craters formed by Grimaldi , Hevelius and Cavalerius. Although the Moon didn't climb higher than 30 degrees above the Southern horizon, magnifications up to 200x could easily be used. High cirrus clouds made the image a bit hazy (and I had to stop sketching after an hour because of thickening clouds) but the seeing was quite good.

- Polarex 75mm f/16 refractor
- Vixen 7mm Orthoscopic (171x)
- White pastel pencil on black paper
- Twello, The Netherlands, April 23, 20.00 UT - 21.15 UT

Absolutely stunning, Roel! BTW, happy belated birthday. :)

When I saw this on FB, it immediately brought to mind a similar sketch I did of it. hevelius-lohrmann-cavalerius sketch and observation

The trio along with Grimaldi certainly make a striking view along the terminator.

Beautiful sketch! I like the different shades of gray in the inner of the craters.

Thanks!

@Erika: that is a truly amazing sketch you made! I like the "widefield" composition, it give a better sense of scale somehow, I might try this myself next time.

What a beauty!!! My sincere compliments, Roel! The edge between the night and day sides is difficult to draw but you caught it beautifully. :D
