Big Round Things

image by Deirdre Kelleghan, Ireland

It was a roughly similar view 400 years ago when Galileo first pointed his telescope at the Moon. Like Deirdre he Chuck Wood

Technical Details
Dec 21st '09; 17:30 UT - 18:15 UT. 200 mm reflector, 26mm eyepiece, FL1200 mm. Pencil rotated. Seeing 2 , Lunation 5.23 days. 0°C.
10:15 AM; Deirdre added this info: I would have liked to do a pastel drawing of the Solstice Crescent Moon but it was too cold. To shorten my drawing time I choose to use pencils. The diameter was determined by a cereal bowl, approx 4 inches. The wonderful Mare Nectaris, was one of the best defined areas. Fracastorius showed its horseshoe edging out of the terminator. Piccolomini's central mountain was wrapped in shadows which created its circular shape. Seeing was not so good, Earthshine was just visible but no details stood out in the dark body of the Solstice Moon as one would expect.
