I spent a couple of weeks recently on a beach vacation, and had some time to experiment with different techniques and media. One of them is attached... sketches of Posidonius crater, based on a photo shown in Norths' "Observing the Moon".

For the sketch on the left, I used #2 and #4 pencils on art paper, this was my warmup sketch. I used a grid to improve the sketch accuracy, you can see some artifacts of that on the sketch.

The right sketch was my second attempt 4 days later using black construction paper and kid's white chalk sharpened to a working point. I used a blending stump and a eraser shield on this one. My conclusion: white on black paper is a great media for the moon. I intend to use this technique during the next lunar month for some real-time effort on interesting objects.

NOTE: the image scan doesn't do justice to my originals, it is too coarse displayed in this format.

These two sketches look great. :cool: You could likely go larger on the scanned images by a factor of 2-3.
The more you sketch using white on black paper the better you will like it. :rainbow:
Practice is a key element for success but I know I don't need to tell you that. Nice post.

Both techniques produce excellent results. It will be up to you to decide which one produces a better representation of what you observe in the eyepiece. I look forward to your future observations with either technique.
