I made an observation of the walled plain Maurolycus (41.8*S, 14.0*E, 71 miles (114 km) diameter) on April 2 , 2009 (02:00 U.T.) using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain (253x). The seeing was average to good (5-7/10) with clear and dark skies (5/6). The central peaks of the Maurolycus rise over 15,000 feet (specifically 15, 518 feet (4,730 meters) above the floor of the plain. Terraced walls are prominent over this massive plain. The terrain over the northwest portion of the plain is pockmarked with small craters and ridges. Baroclus (44.9*S, 16.8*E, 51 miles (82 km) diameter) is the elliptical crater to the southeast of Maurolycus. It contains two smaller craters over it's eastern section. Faraday (42.4*S, 8.7*E, 43 miles (70 km) diameter) lies in shadow to the west of Maurolycus.

What a fine drawing. Do you use a stilus and drawing paallet or mouse? In the upper left of the large central crater is a stippling effect, how was that accomplished?

Beautiful, detailed rendering of a very large and complex crater on the moon. You have captured the crater at a time when the lighting adds much interest to the view.
This electronic method of sketching is quite beautiful and pleasing to the eye. Your attention to detail makes your sketches outstanding. :waytogo: :bow:

Frank :)

Great sketched observation. Very 3 dimensional looking.

That sunlit angle inside of and at the upper left of the crater illuminating all those craterlets is just amazing!

Frank, Mike, MikeV, Sol, and Uwe

Thank you all for your very kind compliments on my Maurolycus observation. I was impressed with the amount of detail that I was noting over the region (especially the floor of the plain). I actually noted detail that I did not record as the Moon was obstructed by my home. The northwest section of Maurolycus is very complex consisting of small craters/pits surounded by bright ridges and rifts as well. This section represented a challenge to render.

I promise to show an example of how I did it soon but I initially recorded the position of the craters/pits then slowly added the bright ridges in sections. One can produce such "mottling" using filters provided by image processing software (e.g. Paint Shop Pro, Gimp, Photoshop, etc.) as well.

I currently use a Wacom Graphire 3 graphics tablet (4 x 6 inch) for my digital renderings. Wacom, as well as other graphics tablet manufacturers, makes a variety of graphics tablets for the digital artist that fits various budgets. The more expensive Intous graphics tablet (2,048 levels of pressure) is great for the dedicated graphics artist but the less expensive Bamboo (512 levels of pressure) is more than adequate for the majority of artists. http://www.wacom.com/index2.php

I look forward to everyone's future observations.

Perfect scope for that kind of detail and captured in an excellent way by your observing. Way to go, Carlos.

Amazing work. I would loose track of all the features. :shocked:

Eric, Roland and Rony

Thank you all for your very kind compliments on my Maurolycus observation. I was very impressed with the amount of detail visible. It was difficult to decide where to start. I am glad that I was able to record it well. The best of luck in your own observations.

A fantastic digital drawing of a very complex crater! You've done an amazing job capturing the floor and rim details. That little black four leafed clover looking crater group on the north rim is spectacularly rendered. As always, your sketch and reports are exemplary!

Thank you for the compliment on my Maurolycus observation. It was a daunting but rewarding task to record this complex crater. I have been inspired by your (and other observers on the forum) wonderful lunar observations. I look forward to those wonderful observations in the future.
