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.

Venus was shining like a million dollar jewel in the early evening sky. The young moon hung low in milky blue atmosphere, giant Jupiter watched the visually stunning occultation unfolding below.



As it got darker more and more detail became visible on the crescent moon.
Between finishing the Venus vanishing sketch and the reemergence of Venus
I put as much lunar detail as possible in the time and under the conditions as I could.

The view as Venus reappeared and once again sparkled like a diamond stuck on the moon was breathtaking .
I quickly place the planet as accurately as I could and then continued to enjoy the view

Here is my sketch from October 28th,2007. I got going early to avoid the predicted cloud cover. I had a long look into the halo around the nucleus. The material emanating from the pin point center seemed to be heading in a more southerly direction than I had observed in previous evenings. I could see darker areas fanning in the opposite direction in the inner halo. A star was visible just inside the outer halo. Because I could see a star through the out gassing then it must be very thin? The star was visually similar in size to the comet nucleus but a little dimmer. Sometimes the coma seemed to momentarily have transparent spaces within it. I have not seen a star in the area of the dark spaces, I wonder if these spaces are filled with dust? All this was visible even though there was a 17 day moon rising almost directly under the icy action.
