Crater Hommel (125 km.) and Pitiscus (82 km.) are both very prominent craters of the lunar southeastern highlands.  I was able to capture both of them near the terminator showing those remarkable shadows creating the illusion of great depth.
At the time of this sketch the Moon was waning gibbous phase. South is up in this sketch. The moon was 18.5 days into this lunation and 87.2% illuminated.

 

Sketching and Equipment:

 

Black Artagain sketching pad, white and black Conte’ pastel pencils, white Pearl eraser, blending stumps
Telescope 16” f/4.41 Dobsonian telescope on an equatorial drive platform at 299x with 6mm eyepiece

Date: 09-18-2019, 06:50- 07:00 UT

Temperature: 32°C (89° F) clear, calm
Seeing: Variable, Antoniadi III(fair)-IV (poor)

Another nice sketch Frank.

I feel complicate to sketch a portion of highlands and you do that so well

Ivan, Ian and Michel,

 

Thank you all for your kind words.

---

Ivan - That 20 inch scope you are standing next to looks like a galaxy killer and I see you have the galaxy clusters sketches to prove it in your posts

---

Ian- Where did you  find that picture of me in the green vest and red necktie?

---

Michel - I have many abandoned southern highland sketches because of getting lost.

Lunar sketchers make me envious, Frank you're not helping. :)

Thank you both gentlemen.

Beautiful Frank. One of the cool things I see as in your work is that its actually an artistic motif. Not a clinical drawing and thats what really comes across here.

 

Superb as always.

 

Pete

Staggeringly good sketch, Frank!

 

Good deep shadows too. 

 

I am going to be completely honest here. 

Having checked Antonin Rukl's Atlas of the Moon where these 2 Hommel and Pitiscus craters are positioned - I can safely say that I have never observed either of them.

We can find them on Map 75 in Rukl's atlas. 

The only crater I have ticked off on that map is Biela which is 76 kms wide. 

 

By the way, Rukl says Hommel was Tycho Brahe's teacher. 

That does surprise me!!

I thought that Brahe knew everything!

 

Clear skies, 

 

Aubrey.

Clint, Norme, Pete and Aubrey,

 

Thank you for your kind words.

 

---

Clint- I know what you mean

 

---

Norme- you need to try one more time laugh.gif

 

---

Pete- I am at my happiest when sketching the Moon or Mars

---

Aubrey- Tycho Brahe was a real party guy, must have been an interesting student

 

Frank :)

PS Thanks for all the likes

Andre,

 

I thank you but I just sketch for fun, lots of practice but not talent like some of the true artists here.

I understand. Like you I do it for fun too and  I saw much better lunar sketches than mine. Me too I have lot to learn.

 

Andre.
