Object Name: M 27 dumbbell nebula
Object Type: Nebulosa Planetaria
Location : Monte Nieddu, Padru, Sardegna
Date : 17/10/2014
Media :graphite pencil, White paper , processed with gimp
observed with dobson SW 10″ goto at 96X with UHC filter.
NGC1514 is a very peculiar planetary nebula. We can see the central star, which is actually a double, shining at magnitude 9.4, while the nebula is somewhat difficult to observe. The UHC filter is helpful. Normally when we observe planetary nebulae, nebula appear much better than the central star… when the central star is seen.

Object name: Ring Nebula, M57
Object type: planetary nebula
Location: Ferrara, Italy
Media: HB pencil, photoshop
Description: I watched M57 using my Dobson 254 mm and 48x magnification with UHC filter. It was gleaming and brand. The sky wasn’t excellent because the lights of the city bleached it but anyway I like this object so much.
Hope you like it!
Object Name: NGC 6888(Crescent Nebula)
Object Type: Wolf-Rayet Nebula
Location: Bercedo, Burgos (Spain)
Media: Graphite pencil, white paper, scanned and inverted with paint.
Equipment: Dobson 8″ + 25mm plössl (48x) + OIII Filter
Sky Conditions: windy, regular/bad seeing, no light pollution
Notes:While I manage to not fall over the telescope because of the gusty wind, I try to sketch that nebula. It shows really faint at the eyepiece field and without the OIII filter is barely visible. The nebula has an elliptical form (I would say it is like a potato) and I can discern the NW nebula’s elliptic edge (supposing that the North and East are 12 o’clock and 3 o’clock respectively at the eyepiece field’s edge) and the nebula’s interior is dark.
• Object Name (NGC 6543)
• Object Type (Planetary nebulae)
• Location (OAB – Bauduen – Verdon – France)
• Date (October 16th 2014)
• Media (graphite pencil, watercolour, white paper, inverted via Paint.net)
To obtain this sketch I use the following optical combinations via the 24” f/d 3.3 on equ. mount of the OAB (Observatoire Astronomique de Bauduen)
An OIII filter to obtain better contrasts. Under a magnification of 240X and the OIII filter the nebulae center darkening is clearly visible.
With the same magnification but without the filter we can easily see the central star with direct vision; anyway we are a little dazzled by the close light of the nebula.
With a magnification of 120X we can observe the structure of one or two of the outer rings.
A 550x magnification allowed me to discern one of the two jets that extend the basic ellipse.
This is my sketch of the Cheesburger Nebula, NGC 7026, a Planetary Nebula in Cygnus. I did the sketch in my Orleans, Ontario backyard using graphite on white paper on Sept 23, 2014, a night of great seeing. It was cleaned up and inverted in Paint Shop Pro. The nebula is quite small, fairly bright with two diffuse nuclei and a hint of darkness between them. Even at 300x in my 12 inch dob I couldn’t confirm if the Cheeseburger has a pickle!
