Please find attached a sketch of the lunar crater Plato and its environs….I used soft graphite pencils to do the sketch on cartridge paper. The colours were then inverted on the computer. This sketch is based on a number of observations I have made of Plato in the last year. I use a Meade LX90 GPS telescope. It has an aperture of 203mm. Plato is one of my favourite regions on the Moon as I love how the crater is filled with deep shadows when the sun is at a low angle.

Crater Davy (35 km.) and the Davy crater chain (catena) were my targets for this evening of sketching and although the seeing and transparency were predicted to be above average that was not the case.
The Davy crater chain is 45-50 km. in extent. It arcs across the floor and eastern rim of crater Davy Y (70 km.). Since it does not line up with any impacts of note it is not likely a sequence of secondary craters. There is also no evidence of volcanic activity associated with this chain. Robert Wichman and Charles A. Wood as well as H. J. Melosh and E. A. Whitaker believe that a comet (or asteroid) may be responsible as it broke up while inside the Earth’s roche limit. As it went in on the moon like a train of meteors it would have created a chain of impacts. A paper published in 1994 by Melosh and Whitaker explains the hypothesis.

NGC 2266 es un cúmulo abierto en la constelación de Geminis; fácil de encontrar; se encuentra a 1º 50’ de la estrella epsilon. Unas cartas de mag. 6,5 son suficientes para localizarle.
De magnitud 9.5, no lo aprecio en el buscador de 9x.
Es un pequeño y llamativo grupo bien separado del fondo que se halla en un campo estelar rico.
Tiene forma de triángulo, en el que destaca uno de sus lados formado por una cadena arqueada de varias estrellas brillantes, cuya magnitud va descendiendo gradualmente desde una de las estrellas de una esquina (mag. 9).
Concentrado al medio, con dos docenas de estrellas pequeñas diseminadas irregularmente y con un fondo moteado debido a las estrellas que no son resolubles con este equipo.
De tamaño considerablemente grande, unos 5’ o 6’.
Observation notes:
NGC 2266 is an open cluster in the constellation Gemini, easy to find; 1 is at 50 ‘of the star epsilon. Letters of mag. 6.5 are sufficient to locate. Magnitude 9.5 do not appreciate it in the search box 9x.
Is on small and striking good fund separate group that is in a rich star field.
It is a triangle, which highlights one side formed by a curved chain of several bright stars, whose magnitude gradually descending from one of the stars of a corner (mag. 9).
Concentrated in the middle, with two dozen small stars scattered irregularly and with a mottled background because the stars are not solvable with this team.

Hi
This is a sketch of the crater Gassendi, one of the most beautiful “fractured floor craters” on the moon.
The sketch was made through my 6” achromatic refractor (TS Individual 152/900), binoviewer, a pair of 8 mm eyepieces and glasspath at 293x. The seeing was variable, usually bad but with very good moments of few seconds that allowed me to perceive the structure called “Rima Gassendi”: a pattern of fractures inside the crater.
I hope you to enjoy with this sketch.
If you wish to read more about this observational report and others, please visit the web of my astronomical group (www.laotramitad.org).
l like the crescent Moon shining on the western sky in remained blue,vermilion hue just after sun set.
lt was always looked as most mysterious, beautiful, or with some a feeling of affection.
Of course l used to see not the horizon alone but l see beyond over in my mind trillions of trillions of moons rising on over its parent planets maybe from in our own galaxy to in the Hubble Deep Fields galaxies. Also l think about trillions of advanced civilizations.

On May 25th, I’ve sketched a famous, nice object: Messier 6, or “Butterfly Cluster”, a beautiful cluster near the end of the Scorpion, celebrating a historical date in Argentina: 205 years ago, argentinians started to organize a revolution against the Spanish Empire which succeed and helped a lot to declare our Independence six years after that initial revolution, now called “Mayo’s Revolution”, which happened on May 25th, 1810.
I used a newtonian telescope SW 150/750 f5, graphite pencils 4B, 2B and HB, on a white paper, and then edited with Photoshop tool.
As for the title, it’s the name of a famous argentinian rock song, called “Mariposa Pontiac/Rock del País” (translated: Pontiac Butterfly/Country’s Rock), from a very famous band here, “Los Redondos”.

Assessments: I can see a bright star that I consult with the Stellarium program, I think it can be HIP 43519, the other very faint stars, it costs me perceive, after a while to adapt, I’m seeing a number of stars that make visually cluster resembles as a bunch of grapes, is what comes to mind.
Comentarios: Puedo ver una estrella brillante que consultando con el programa Stellarium, creo que puede ser HIP 43519, el resto de estrellas muy tenues, me cuesta percibirlas, tras un rato de adaptación voy viendo una serie de estrellas que hacen que visualmente el cúmulo se asemeje como a un racimo de uvas, es lo que me viene a la mente.
Friday evening just before the altocumulus clouds of the approaching depression covered the sky, I could do another sketch of the moon: This time it was crater Posidonius and its surroundings.
Ah, by the way, this time I tried a new pen: For the bright areas (e. g. the western rims of Posidonius A and J), I took a whitecoal pen instead of chalk pen. That provided much brighter contrast.
Another novelty for me: I didn’t use a diagonal but an Amici prism, so that the view in the eyepiece wasn’t mirrored at all. The view was a bit less bright, but for the moon it’s still bright enough.
