A Rupes and a Rima

Rupes Recta

Rupes Recta and Rima Birt
Sketch and Details by Balázs Benei


This is my other sketch, I made it at the beginning of April. Rupes Recta was very easy to observe, it was totally in the field of vision. Rimae Birt was not so easy but I could see it firmly. The seeing was very good at times, I could observ the crater Birt D, which had only 3km (~2miles) diameter. I think this was the end of the definition of my telescope. I made the sketch with graphite pencil.

My equipment: 110/800 (4′) Newtonian reflector, 2x barlow, 10mm eyepiece, 160x magnification.

Yours sincerely

  2. How long did it take you to sketch that magnificent landscape of the moon?

    It’s just dwo circle, and one line

    Sorry ….Sorry i have forgotten, there are horizontal and vertical axis too. 🙂

  3. Ok, you’re right. But it was just a try-out to send in this sketch. It was a surprise for me too. Yes, maybe it can be a joke 🙂
