Edge of the Schiller-Zucchius Basin new
      #3884505 - 06/24/10 09:19 PM Attachment (37 downloads)

With no specific sketching target in mind, I was examining the south terminator region of the moon and noticed it was showing what is considered to be an unfavorable view because it was turned away from the observer.
There was a poorly defined part of a scarp-like ring partially visible under craters Rost A, Weigel and Weigel B. This ring is just beyond the Schiller-Zucchius basin center which was not yet illuminated by sunlight. The southeastern portion of this ring illuminated by the rising sun presented a half dark, half illuminated pathway that ended at the terminator. I found this view at the eyepiece quite fascinating and had some difficulty capturing it correctly.
The “unfavorable” libration of this part of the moon near the terminator contributed to the shallow angle view. Even the appearance of famous, elongated, paramecium shaped crater Schiller was unusual.
These are the kinds of surprises that get me motivated to sketch the moon.
A beautiful photo of this region of the moon ( by Carmelo Zannelli) was featured on June 10, 2010 at LPOD. http://lpod.wikispaces.com/June+10,+2010

Frank,

An outstanding observation of the lunar limb showing of the Schiller-Zucchius Basin. You have captured much complex detail over this region. The complex craters and shadows are very nicely recorded. Thank you for sharing it with us all.

I took the liberty in cleaning the limb a little, adjusting the levels, and blurring it al little. I hope that you like it.

Carlos

Dear Frank, what a great sketch! Wh should not resign to sketch a region because of it not so favourite libration.

Frank,
Great sketch.


Off topic What would be a good moon book so I can learn the parts/names. Also an iTouch app.

Thanks for sharing:D

Jef, Galaxian, Tom, Carlos Uwe,and Lynn,

Thank you all for your kind comments and response to my lunar sketch.

Carlos- additional thanks for brightening and adjusting the image of my sketch.

Lynn - for starters you could download for no cost Alan Chu's Photographic Atlas of the Moon. It is provided free of charge and Mardi Clark c.n. member(photonovore) makes the English download available through her excellent website http://www.cityastronomy.com/moonbook-mirror.htm.
The Virtual Moon Atlas is another download you can make free of charge http://www.ap-i.net/avl/en/start
Sky and Telescope's laminated Moon Atlas can be purchased at Amazon.com for about $5.
Information about other moon books that are favorites of Cloudy Nighters can be found over in the c.n. lunar forum (lunie bin).

*Very* nice, Frank. I see why this area caught your eye--it looks unusual. Schiller always looks good, yes? Paramecium-like is a good description.

Frank,

Wonderful lunar sketch - thank you for sharing. I was studying some lunar maps the other night and noted the Schiller-Zucchius basin. I wanted to sketch it myself, but persistent clouds kept me indoors. Glad to enjoy your sketch!

Frank,

Tremendous sketch and I enjoyed studying it. Thanks for posting it.

I agree that the S&T Laminated Moon Maps are very good, they are my first choice of use in the field. S&T Moon Map If your using a reflector get the mirror image one S&T Moon Map Mirror . Alan Chu's Photographic Atlas of the Moon is excellent, and if you have a laptop with wireless connection you can use it in the backyard (no worries about LP with the moon). I also enjoyed the book Moonwalk with Your Eyes, A Pocket Field Guide by Tammy Pletner. It walks you through a guided tour of the moon based on the phases. Enough there to keep one busy for some time. You can preview it here at Amazom.

great sketch of the crator Schiller, glad you were able to get some observing in between rainstorms.

What a great sketch. I'm just in the process of learning to work with pastel (only 5 sketches so far) and I want to render such detailed region a high magnification too. Sadly the Moon doesn't rise that high this time of year in Holland (52 degrees north) so high powers are useless. I'll stick with full disk drawings for now...

Beautiful sketches like these make me hungry for autumn (Am I crazy!).

I think those features at the very edge of the Moon are the nicest. Because of the low viewing angle you get that space-flight feeling. It's all but unfavorable to me!
