Pitatus is an old, large 97 km. diameter crater on the edge of Mare Nubium. The floor of this crater has a linear central peak which was casting a fine elongated triangular shadow at the time of this observation and sketch. To the south craters Wurzelbauer (88 km.) and Gauricus (79 km.) could be seen; both of these craters show badly warn rims; both much older than Pitatus. Attached to the northwest rim of Pitatus is the crater Hesodius (43 km.). At about the eighth or ninth day of lunation you can observe the famous “sunrise ray” beaming across the floor of Hesodius through a break in the wall with Pitatus. This is certainly a sight worth observing.

black Conte’pastel pencils and blending stumps.

Object Name : NGC 40
Objet Type : Planetary nebula
Location : Melgar de Fernamental ( Spain )
Date : 2014, Septembre 3d
Lunar day 9
Drawing instruments : Graphite pencil , GIMP program to invert the colours
Equipment used : 8″ Newt , Baader ortho classic 6mm , Astronomik UHC filter

The object is easy to find but rather dificult to see , the central star hides the nebula

Clear skies

NGC 6995 (Veil Nebula)

Object Name: NGC 6995
Object Type: Supernova Remnant
Location: Morella (Spain)
Date:31/08/2014
Media: white paper, graphite pencil, 7B, HB, scanned and inverted with Paint
Equipment: Newton 8″ + plossl 25mm + OIII filter
Sky Conditions: Clear sky, no light pollution, good seeing and transparency
Notes: Without OIII filter that nebula appears as faint “cloud” at the eyepiece field but I can see some structures along the nebula. Using OIII filter the image is incredible!, I can see much more details and structures and the contrast between the sky and nebula is higher. One of my favourite objects, awesome.

Thank you.

Open Cluster NGC 6940 in Vulpecula

Greetings to all the ASOD community, I share this sketch of a fascinating open cluster in the constellation Vulpecula. It is amazing the eyepiece, lots of stars of various magnitudes with asterisms of all forms in the imagination and also a double star, all accompanied by the gaseous layer that surrounds the star cluster. Very good image even at low power.

Best regards.

Crater Gassendi and the northern part of Mare Humorum

Lunar crater Gassendi and the the northern part of Mare Humorum - September 5, 2014
Lunar crater Gassendi and the the northern part of Mare Humorum – September 5, 2014

Here is a sketch of the Moon on the 5th of September from my backyard
in Adelaide, South Australia.

The moons phase was waxing at 83%, with only the very western edge
still in shadow. I observed with a C11 SCT. Seeing was quite
reasonable, so I took a 15mm eyepiece + 2x Barlow for a close look.

The shallow illumination on Mare Humorum made the creases on the mare
floor stand out. Crater Gassendi, toward the bottom, showed stark
shadows. Rimae Hippalus was visible, passing through the partially
submerged crater Hippalus at the top right. Because I used a diagonal
prism, the sketch is mirror imaged.

I used pastel chalks and black and white pastel pencils on black
paper.

Goldilocks & The 3 Sun Bears

Aloha!

While observing our ever changing Sun today I was struck by a grouping of prominences on the western limb. All of them of high intensity and curving towards the same direction. They made me think of the story of Goldilocks & The 3 Bears!

Object Name: M51
Object Type: Galaxy
Location: Morella (Spain)
Date: 30/07/2014 – 22:18 UTC
Media: white paper, graphite pencil, 7B, HB, scanned and inverted with Paint
Equipment: GSO Newton 6″ f/5 + Hyperion 13mm (57x)
Sky conditions: Very good seeing and transparency, no light pollution and clear sky

Notes: At the eyepiece field I can see two white cores of different brightness and size, surrounded by a faint and grey nebulosity. M51B(smallest galaxy) has elliptical nebulosity and M51A has round nebulosity. It’s not difficult reveal two spiral arms around M51A’s core, which one of them ends in M51B. This is my first astronomy sketch.

Thank you.

Dorsa Euclides F and Euclides

Object Type: Moon

Location: Tarragona – Spain

Usually it is not easy for me to draw the moon, and if I have to draw something as delicate as lunar wrinkle ridges (dorsa / Dorsum), things get complicated. But the time I spent enjoying Dorsa F Euclides, Euclides and the neighbors ghost craters worth it.

For more details of my observation you can visit my blog:

Thank you and best regards.
