Location: Maastricht – Netherlands
Date: April 18th, 2013 – 19.00h UTC
Media: Graphite pencil 5B on white paper
Seeing: Variable, with moments of very good conditions
Equipment: 12″/F5 Dobson – Nagler 3-6mm Zoom – 375x

Height above the horizon 36 º Observation at sea level in Barcelona (Spain)
Media: pencil in white paper, Microsoft Paint
Notes:
Horizontal image investment because used diagonal mirror.
The predominant color on the planet is a very pale yellow (at other times showed an intense golden) contrasting with some greyish belts with ill-defined irregularities. It clearly shows the shadow of the planet on the rings.
The Cassini Division shows a high contrast and a black is intense and well defined.
I could clearly see the satellites Titan, Rhea, Dione. Tethys only very weakly.
Enceladus, I’d be on the limit of this equip, but It was not possible to distinguish. Mimas is beyond the scope of this opening.
Hello asod, this sketch show is pretty irregular galaxy. During the observation, I could visualize the extreme deformities, without much effort. A large object that caused a great sensation through the eyepiece. Do not stand by its size but by its peculiar shape.
Regards.

Notes: This sketch was executed with a Celestron C925 on a CGEM with a Swan 40mm EP and a Williams Optics 45º erecting prism diagonal at 58X. The wind was 10mph, Temp: 47ºF, Humidity 24% under a first quarter moon at 2130. The Lit. Rho is 12.8″, Theta is 280º. I measured the pair with a Meade 12mm Astrometric EP and obtained an average Rho of 14.8″, and average Theta of 218º.
I am interested in the nebulosity of the three NGC objects that are included in the field of view. I plotted 25 field stars including one outside the F.O.V. to the west and two outside the F.O.V. to the WSW.

Bonjour,
Voici un dessin de la comète C2011L4 Panstarrs fait avec un dobson de 345mm, focale 1504mm et un oculaire de 40mm (37 fois de grossissement)
Elle est encore bien brillante et très belle à voir.

Hello,
Here is a Sketch of the comet C2011L4 Panstarrs done with a 345mm Dobson, 1504mm focal length and an eyepiece of 40mm (37 times magnification).
It is still bright and beautiful to see.

Hi All. M67 has many nebulosity in the cluster.
And M67 is one of the oldest cluster in the sky.
I give a guess that is related to nebulosity…? I don’t know exactly 🙂

Hello friends artists,
this is my sketch of the Panstarrs, one of the comet of 2013. The tail of the comet was long enough and the head was very light. This is my first comet and I liked it so much. I observed it with a 100 mm telescope, at 7,30 p.m. It was visible with naked eye like a 2 magnitude star. Moreover I observed it with a 20×80 binocular, and it appeared equal, more or less.
Hope you like this sketch! And I hope you understand my english!
Hello,
this week I take the chance at the first April to sketch Messier 64. First I observed the supernovae in M 65. I needed more than 2 hours to confirm the sighting with my 10″ ACF. I appreciate the brightness was somewhat less 15 mag and my telescope was at its limit. The conditions were quite good (no wind, temperatures about 0° C, dry air). After this I enjoyed the nice galaxies in Coma Berenices and Virgo Cluster. Markarians Chain is always feast for the eyes. M 64 was the last galaxy in this observing session and so took my pencil and paper block to hold the impressions.
Unfortunately, there were problems with my scanner. The finer details don´t come out and some areas are to brihgt. I hope you like the result anyway.
Object: Galaxy
Name: Messier 64
Telescope: 10″ ACF SC
Eyepiece: 22mm Nagler
Magnification: 120x
Location: Germany near Tauberbischofsheim
Medium: White paper and pencil – inverted colors with Windows Paint

As the evening progressed the sky became mostly clear with some ground fog adding to the light scatter and the inevitable falling temperatures of an early spring night. Nevertheless, it was good enough for some observing and sketching. Crater Theophilus (100km.) was more than 450 kilometers from the terminator but remained an attractive target in the eyepiece as the Moon cleared a nearby building in my southeast.
Theophilus is a complex Erastothenian era crater at just over 1.3 billion years in age with large central peaks of deep crustal material that formed on the rebound from the initial impact. The appearance looks fresh when compared to its much older Nectarian period neighbor Cyrillus (100 km.). It was evident while observing this pair that Cyrillus was showered with ejecta from Theophilus and prior millennia of countless strikes by incoming rocks from space. The central peaks of Cyrillus are smaller, more muted and worn down. 300 kilometers to the west of Theophilus the Apollo 16 astronauts Charles Duke and John Young collected 96 kilograms of rocks over 3 days back in 1972 which included some ejecta from the Theophilus formation.
Remote sensors on the orbital spacecraft Chandrayaan-1 detected Iron rich Magnesium –Aluminum oxides on the central peaks of Theophilus adding to the knowledge of the composition to the deep lunar crust as indicated by a publication last spring.
Two other craters included in the sketch are Mädler (29 km.) also of Erastothenian age and Ibn-Rushd (34 km.) an ancient one at more than 3.2 billion years.
