Object name: NGC 1907
Constellation: Auriga
Object type: Open Cluster
Location: Dehnamak-Semnan-Iran
Date: 2011/12/21.
Time: 11:45pm local time (+3:30 GMT).
Media: Graphic pencil white paper-photoshop edit.
Equipment: 200mm Dobsonian telescope-f/6-focal length 1200.
Conditions: Clear sky with a little dust near the horizon
Object Name: Comet C/2009 P1 Garradd
Object Type: Comet
Location: Caldera Rim Observatory, Jemez Springs, NM, 8300 ft. elevation
Date: March 23, 2012, approximately 10:15 PM
Media: Pencil on Tracing Paper, Multiple Layers for Color
Notes: We used a 20-inch F/5 telescope at 195X (13mm Ethos). This drawing is a composite of two overlapped sketches, one of green-grey luminosity, another of a dark red background that was observed. The sketches were scanned with a Kodak 10 megapixel digital camera while backlit by a red light, and were then aligned/combined in Photofiltre, to create a color image.
North is to the right in the image. We observed what appeared to be two tails, one green-grey, and another dark red (at the edge of visibility). When the comet nucleus was moved out of the view, we could follow the red “tail” for more than 1/2 degree, and it curved to the North. Distinct streamers (lines) could also be seen in the green-grey tail–at the edge of visibility. The faintest stars in the drawing are about magnitude 14.7.
The comet moved and changed during the observation. The drawing should be representative of what was seen at approximately 10:15PM.
Mars – March 2012 (Move mouse over image to view labels.)
Overview of my Mars sketches in March 2012.
During March large areas of cloud and haze where visible.
Especially till the end of the month the region of Hellas Planitia
appeared very brigth with overlayed clouds.
Sketching:
Pencil on white paper, black background added in PS
Object Name: Bullialdus.
Object Type: Lunar Crater
Location: Bristol
Date 3rd March 2012
Media: Drawn at scope with graphite pencil on white paper then scanned and processed using Sketchpad Pro on ipad.
I used an 8″ SCT with a mix of 20mm bino viewers plus 8-24mm Hyperion zoom lens.
Weather was good. The crater was not optimal for shadows but the tiered wall could be seen, as could the multiple peaked mountain in the centre.
I have blurred the result to more closely approximate the actual viewing experience.

Beautiful evening with the 4 day old Moon above Venus and the planet Jupiter above the crescent Moon. After a careful look at the crescent Moon through the telescope at low power, I needed to decide if I should attempt a sketch of the beautiful view of western Mare Crisium or the crater Furnerius which was the easier target. Considering the air temperature which was cold, I took the easy way out and sketched Furnerius.
With the terminator well past this region, I knew I would have time to go indoors and warm up if I got too cold. I centered the eyepiece on my target and turned on the equatorial drive platform. Furnerius is a large 125 km. crater that has the appearance of the old pre-Nectarian period crater it is. Its walls and floor are battered with many small craters and Rima Furnerius was detectable on the northern side of the floor. Crater Fraunhofer (57 km.) another old crater was sketched to the south and much younger Stevinus (77 km.) was showing off its central peak to the west.
Sketching:
For this sketch I used: black Strathmore 400 Artagain paper, white and black Conte’ pastel pencils and a blending stump.
