Here's my entry - the Leo Triplet:
High Resolution Version and more image information available at http://www.astronome...php?c=113&p=490
Base 200mm image is from 119 x 10 min subs at ISO 800 plus 64 x 5 minute subs (25 hours total) at ISO 800 captured with a Gary Honis modified Canon 450D (Baader mod) using a Canon EF 200mm f/2.8L II USM prime lens at f/3.5. Guiding was through a Celestron C-8 using a ONAG on-axis guider, Lodestar autoguider and Phd Guiding.
M65 and M66 detail image is from 89 x 5 minute subs at ISO 1600 (7 1/2 hours) via an orange tube Celestron C-8 at 1160mm (f/5.8) with the same modified Canon 450D. Guiding was through a Celestron C-8 using a ONAG on-axis guider, Lodestar autoguider and Phd Guiding.
NGC 3628 detail image is from 329 x 3 minute subs at ISO 1600 (16 1/2 hours) via an orange tube Celestron C-8 at 1260mm (f/6.3) with the modified Canon 450D. Guiding was with an Astro-Physics 80m f/11 guidescope using an Orion SSAG and Phd Guiding.
Thanks for looking!

I'd like to have another go at the contest. This time with my drawing of M46 and its lovely little planetary NGC2438. It took me about two hours behind the eyepiece to make this sketch (pencil on white paper) and perhaps twice as much elaborating it on my PC. I tried as well as I could to render the 3D-effect of this magnificent and rich open cluster, especially since I observed it with my 2" binoviewer and a couple of 24mm Explore Scientific 82° eyepieces. I hope you like it...

I would like to submit my latest lunar sketch to the contest:
Object Name: Grimaldi, Hevelius, Cavalerius
Object Type: Lunar craters
Location: Twello, The Netherlands
Date: April 23, 2013
Media: White pastel pencil on black paper
It has been more than a year(!) since my last lunar sketch, but on the evening of April 23th I dragged my 3" f/16 Polarex refractor outside for some good old sketching.
The most prominent feature on the lunar 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. The sketch was made through an old 7mm Orthoscopic eyepiece (171x). The image is mirror reversed (north=up, west=left).

I observed the crater Ptolemaeus at the terminator line on October 11th through my Nexstar 5i Cassegrain at medium power magnification and through high thin clouds at times, the seeing was medium to fair, and produced this dry pastel sketch including the whole moon at near 29 inches diameter onto 100% cotton fiber black pastel paper. As a final touch and favorite theme, I added an artists conception as seen from the surface of the moon at Ptolemaeus.

Hereby I would like to submit my sketch of Langrenus crater made December 19th.
Although the Moon just peeked over the warm roof tops at the end of the evening, I couldn't resist myself to make a quick sketch through my Polarex Unitron 75mm f/16 refractor. The seeing was horrible but at a magnification of 92x the image was quite pleasing. Langrenus is big enough (133 km wide) to view even at low power, and yesterday it proved to be a nice target for sketching. The floor of the crater was already pitch black, only the top of the outer rim received some last sunlight before entering a cold, two week night. The little triplet of craters Naonobu, Bilharz and Atwood made the view even more appealing.
I made the sketch with a white pastel pencil on black paper.

Here's my entry for Jan 2014 sketching contest.
I chose this one because it was the most unique so far this season. The Io transit shortly after opposition was amazing in that I suspected being able to observe Io eclipse it's own shadow. It was also faintly visible against the SEBn.
The festooning was pretty nice, but the cloud features in the north were quite nice even if LRS-1 was missed. Some of the rifting in the SEB was unique, as well, in that it's not often observed. Neither are the ovals in the SSTeB preceding the GRS. It was a great night worthy of sharing.
This sketch was made beginning 1700UT on 8 Jan from Luzon in the Philippines. Seeing was good to excellent, transparency was average. Equipment used was a 150mm MCT on an undriven EQ mount. Magnification was 240x with 8mm TMB II.
I'd prefer to submit the sketch in my avatar, it is more detailed and maybe a little better rendered. This one is more unique, so it was a tough choice. I hope I chose well. The write up is here.
