74% Waxing Gibbous Moon

I decided on cruising the Moon tonight, but this time, sketch pad in hand, I did a rough sketch of the entire visible surface. When I had finished, I was able to verify with Google Earth's lunar maps what I saw and where I went. I'm just not that familiar with the lunar features yet, so I figured this would be a good way to learn.

I'm using a Zhumell Z12 12" F/4.9 with a 13mm Baader Hyperion eyepiece (115x 0.68° TFoV) and an Orion Variable Polarizing filter.

I started in the Northern region and cruised down the terminus into Mare Imbrium. On the North side of Mare Imbrium, I could see small mountainlets and the worn-down crater Plato with its nearly flat floor. Cruising East along the edge of Mare Imbrium and turning South with it, I came across crater Aristillus, Autolycus, and Archimedes. Turning West, I came to Timocharis and Lambert then South again to the smallish crater Pytheas. South of Pytheas and moving beyond the border of Mare Imbrium is crater Copernicus surrounded by a maze of wrinkled mountains and valleys of light and shadow. Very cool. :cool: A little East Northeast is Eratosthenes also surrounded by a mountain maze, then Sinus Aestuum. South from Copernicus along the terminus I could see Reinhold and Reinhold B then South into Mare Nubium, I could see Bullialdus and its satellite craters Bullialdus A and B. I sketched these 3 craters as my first lunar sketch because they were relatively easy and looked doable given a few hours.

Here's my sketch of Bullialdus and Bullialdus A and B. I switched to the 5mm Hyperion (300x 0.24° TFoV) for the close-up:

I tried lunar sketching before and the results were horrible. I practiced sketching from photographs a few times and got better. Last night was my first night "officially" at the eyepiece and somewhat successful. Hopefully, I'll be able to pull off some more ambitious sketches in the future, but sometimes I just don't get enough time at the eyepiece. :(

It is clear you enjoyed doing this and the results look just great. :cool: :rainbow: :bow:

You can be proud of this sketch. Be carefull, sketching the moon can be addictive. Stop before it's too late ;)

You can make the size of the scanned sketch smaller. Mostly it gives an even better result.

Yes, I'm starting to feel the addiction. I was looking at some of the more complicated lunar features and thinking about tackling them already. :)

I'll see if I can shrink them down.

Hey, thank you, Frank. The darks are darker and the lights are lighter. Looks like it adds depth. Definitely better. :)

Very nice sketch indeed. I've always found sketching the Moon difficult to do so I'm very impressed. :bow:
