Description:
A rarely observed protoplanetary nebula I’ve first read about in Cloudy Night’s Sketching forum. It’s as small as expected, but much fainter. Elongated to the N-S, with a clearly visible dark band divinding the nebula to to halves, when the seeing gets better for a few moments. Reminds me of a faint little nearly edge-on galaxy. I haven’t checked photos of this object before my observation, so I’m quite surprised now that I’ve seen the dark band, because even on a sketch made with 600mm scope it does not show up. But I know that my eye did not lie. A highly recommended gem.

PanSTARRS and the Andromeda Galaxy

C/2011 L4 (PanSTARRS) and M31
C/2011 L4 (PanSTARRS) and M31

I made this sketch using my 15×70 binoculars at 1:45 UTC on 4/5/2013. I was just able to get both objects in the the field of view. The comet was brighter than M31, particularly in the core, but smaller. The comet’s tail was noticeably wider than it was when I observed it a few weeks earlier on 3/13. It was an interesting conjunction but was hard to get a lot of detail, M32 and M110 were not even visible, because they were both about 10-15 degrees from the horizon.

The Peculiar Shape of NGC 4449

NGC 4449
NGC 4449

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.

Object Name: Double Star HR 7169 & 7170 in Corona Australis with NGC 6726, 6727 & 6729.
Object Type: Double Star with three Bright Nebulae
Location: The Summit of Haleakala on Maui at 10,000 ft. elevation
Date: July 24, 2012
Media: Light pencil on white paper, scanned to GIMP, and color inverted, Labelled in Mac Preview.
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.

M 64 – Black Eye Galaxy

Messier 64
Messier 64

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

NGC 3079 – “Flocky galaxy in Ursa Major”

NGC 3079
NGC 3079

Object Name: NGC 3079 (UMa)
Object Type: Barred spiral galaxy – edge-on view
Location: Hombeek, Belgium
Date: 14th March 2013
Conditions: Clear transparant sky – seeing 2/5 ant. , NELM 5.7 (UMi method)

Optics: Celesctron CGEM1100 (SCT 11” f/10), Hyperion 10mm (280x), FOV 15arcm
Media: Graphite pencil on white paper, inverted scanning

Notes: This observation was made during one of the few clear nights of the past winter period with tempertaures dropping to minus 10°C. Galaxy NGC3079 is one of the better objects in the Hershel 400 list and was at first impression quite difficult to see with diffuse and faint impression. When using averted vision the object displays a richdom in details with an overall flocky appearance, 6:1 elongated and a faint irregular core that extends to the north in a triangular brightening. The southern core area is very flocky. Two bright areas are clearly visible on both sides of the core, of which the detail in northern area is more explicit, sharply defined with a darker area towards the east and resembling a second core. A real nice object!

Clear skies,
Tom Corstjens
