M97 (Planetary nebula)
Also known as: Owl nebula, NGC 3587
Right ascension: 11h 15m Declination: 55° 1'
Constellation: Ursa Major
Date/time: 2008.04.24 20:30 UT
Equipment: 12" f/5 Newtonian
FoV: 20' Magnification and filter(s): 167x + UHC filter(s)
Seeing: 3/10 Transparency: 3/5

The M97, also known as the Owl-nebula is a very spectacular, famous planetary, in the vicinity of M108. It's a nearly regular circle, slightly elongated in E-W directions. Also on the Eastern and Western corner one can find two darker spots, the eyes of the owl. The planetary itself is quite an easy object, looks much brighter than the 11m as listed in catalogues, a homogenous shape with sharply fading edges. Discovering the eyes is a bit harder: especially the Western spot is tend to blink. Using your averted vision helps a lot to see the details. I was using my Baader UHC filter to finish this sketch, however according to my experiences a slightly better seeing helps much more than the filter.

M57 (Planetary nebula)
Also known as: Ring nebula, NGC 6720
Right ascension: 18h 54m Declination: 33° 2'
Constellation: Lyra
Date/time: 2008.06.10 21:30 UT
Equipment: 12" f/5 Newtonian
FoV: 14' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 4/5

The famous Ring nebula of the Lyra constellation is well-known even for people less obsessed with astronomy. An interesting fact is that its visual surface brightness is about half magnitude better than its photographic surface brightness thanks to the elements that build up its spectra, therefore it's worth taking a look of this shiny planetary nebula with any kind of telescope. Its position is very easy: you can hardly miss it on the line connecting the stars beta and gamma Lyrae. Its central star (14.7m) was barely detectable for me if at all, even with averted vision. I think it demands darker skies. The UHC filter did not help much on the view, but large magnification is really neccessary.

M27 (Planetary nebula)
Also known as: Dumbbell nebula, NGC 6853
Right ascension: 20h 0m Declination: 22° 43'
Constellation: Vulpecula
Date/time: 2008.06.10 23:30 UT
Equipment: 12" f/5 Newtonian
FoV: 1° Magnification and filter(s): 71x + UHC filter(s)
Seeing: 7/10 Transparency: 4/5

A huge planetary nebula in the constellation Vulpecula. The UHC filter enhances the contrasts somewhat, but it is a wonderful sight even without it. The shiny central part resembles the core of an apple to me and has a direction of N-S. Its far from being homogeneous: in its Southern half a brighter area can be observed. On the Western and Eastern sides of this core are two fainter areas that complement it to a whole "apple". The Western one of these looks much brighter.

NGC 6210 (Planetary nebula)
Also known as: Turtle nebula
Right ascension: 16h 44m Declination: 23° 48'
Constellation: Hercules
Date/time: 2008.06.22 21:00 UT
Equipment: 12" f/5 Newtonian
FoV: 15' Magnification and filter(s): 250x
Seeing: 4/10 Transparency: 4/5

An unexpectedly bright, but tiny (20") planetary nebula. If we already know what and where must we look for, it is an easy target. However, for me it was a really tough one for the first time: it took some time to realize that the mysterious "star" that shouldn't be there according to the star maps is in fact the planetary itself. At 71x it is completely star-like, however at 250x we are able to catch its smaller details too. It has an almond shape, elongated to the E-W directions, with a bright white core. Also towards these directions I could discover two faint little horns. It requires high magnification, and good seeing.

NGC 6543 (Planetary nebula)
Also known as: Cat's eye nebula
Right ascension: 17h 59m Declination: 66° 38'
Constellation: Draco
Date/time: 2008.06.29 22:00 UT
Equipment: 12" f/5 Newtonian
FoV: 14' Magnification and filter(s): 250x + UHC filter(s)
Seeing: 7/10 Transparency: 5/5

The first thing that catches your attention on this planetary nebula is its marvellous sea blue colour. After that you may notice its asymmetric shape, which is just like two halves of nut sticked together, slided a bit apart. With the UHC filter on the view is even more spectacular: many additional faint details appear around the planetary, and it also appears slightly larger than without it. It demands for a very calm, stable atmosphere. The oval planetary has a longer axle on the N-S direction.

NGC 7026 (Planetary nebula)
Also known as: The Cheeseburger nebula
Right ascension: 21h 5m Declination: 47° 39'
Constellation: Cygnus
Date/time: 2008.09.03 00:00 UT
Equipment: 12" f/5 Newtonian
FoV: 16' Magnification and filter(s): 250x
Seeing: 6/10 Transparency: 4/5

I find this object much smaller (around 0.3x0.4') than what is suggested by the values in catalogues (0.8x0.8'). It's a fairly blue, very bright planetary with a shape resembles a diamond, divided in N-S direction by a dark belt of matter in the middle. Its name is very felicitous when taking a look at its entire shape: Cheeseburger nebula. I can detect an additional faint nub on the NW part of the object. Requires large magnification and a very calm atmosphere.

NGC 7027 (Planetary nebula)
Also known as: Magic carpet nebula
Right ascension: 21h 7m Declination: 42° 14'
Constellation: Cygnus
Date/time: 2008.09.04 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 16' Magnification and filter(s): 250x
Seeing: 6/10 Transparency: 4/5

Also known as the Magic carpet nebula, this planetary is quite large, with a shape that fits its name well. The surface brightness varies widely, with a brighter larger part to the NW, and a smaller bright portion to the SE, divided by a fainter part. Its colour is remarkably blue, the dark parts are very spectacular with their deep shade of blue.

NGC 7008 (Planetary nebula)
Also known as: Fetus nebula
Right ascension: 21h 1m Declination: 54° 33'
Constellation: Cygnus
Date/time: 2008.09.02 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 12' Magnification and filter(s): 250x
Seeing: 6/10 Transparency: 4/5

A very large planetary nebula in the Cygnus constellation, also known as the Fetus nebula. Its naming perfectly suits its look, which is very conspicious. Its an asymetrical shell with widely varying brightness and an enormously shiny area to the NE. The central star is a 13.2 magnitude one, easily detectable because its surrounding dark areas. To the East from this you may notice another star of the similar colour and luminosity. I cannot see any hint of colour throughout the planetary. It's a nice object even at low powers of around 100x thanks to its relatively high surface brightness, therefore it may be a reachable target for small telescopes too. I've tried using my UHC filter, but the results were worse than without it.

Trumpler 3 + PNG138.1+04.1 (Open cluster)
Also known as: Tr 3
Right ascension: 3h 12m Declination: 63° 15'
Constellation: Cassiopeia
Date/time: 2008.01.26 20:00 UT
Equipment: 12" f/5 Newtonian
FoV: 45' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 3/5

This open cluster is located in a star field that's free from bright stars. Its most remarkable figure reminds me of a reaping-hook, and is composed by four stars between magnitudes 9 and 10. These are also considered the brightest members of the cluster, besides these only a couple of stars of 8-10m are visible in the field of vision, but most of the members are fainter than 12m. For about 20' to the south is the planetary nebula PNG138.0+04.1, but its nebulosity can only be suspected even by using averted vision - the large, 5.5' diameter planetary cannot really be seen even with the UHC filter on. However, its 13m central star can be found and a little haziness can be detected next to this star that is probably illuminated by the brighter stars next to the central one.

NGC 7662 (Planetary nebula)
Also known as: Blue snowball
Right ascension: 23h 26m Declination: 42° 35'
Constellation: Andromeda
Date/time: 2008.11.18 19:00 UT
Equipment: 12" f/5 Newtonian
FoV: 15' Magnification and filter(s): 250x + UHC filter(s)
Seeing: 5/10 Transparency: 3/5

The planetary, also known as Blue snowball nebula looks planet-like even on powers as small as 45x, with a charming cyan colour. I think this is the planetary, that looks nice even is a theatre-binocular. Naturally, a filter is unneccessary to view it, however I've found that by using a UHC filter its size expands, especially to the Northeast, where a dark blue thin arc shows up. Finding this planetary is not hard at all, but it's a bit tricky, because the viewfinder displays it just like a bright star which you are unable to find on your maps. It has a perfect circular shape of a diametre of 0.6', with a brigthness of about 8m.

NGC 2392 (Planetary nebula)
Also known as: Eskimo nebula, Clown face nebula
Right ascension: 7h 30m Declination: 20° 54'
Constellation: Gemini
Date/time: 2009.01.24 18:40 UT
Equipment: 12" f/5 Newtonian
FoV: 15' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 3/5

Also known as the Eskimo or Clown face nebula, this planetary is the real gem of the constellation Gemini. It's a very bright object, showing much details and is quite unresponsive on filters. I estimate the brightness of its tiny, star-like core about 11 magnitudes, with two perfectly regular concentric circles around it, each with surface brightnesses about 1 magnitudes fainter than this. The diametre of the inner circle seems exactly the half of the entire object.

NGC 6804 (Planetary nebula)
Right ascension: 19h 32m Declination: 9° 15'
Constellation: Aquila
Date/time: 2009.08.18 21:00 UT
Equipment: 12" f/5 Newtonian
FoV: 14' Magnification and filter(s): 250x
Seeing: 4/10 Transparency: 5/5

A faint little planetary discovered by Herschel. It has a diametre of 1', even at 71x it does not look like a star, but rather like a large, fuzzy little spot. By increasing the magnification, you may notice a slight elongation in the WSW - ENE direction. By some more careful examination, a slightly brighter central region is visible to the ENE, with a faint star on its edge, which I thought to be the central star. However, as I went on with the sketching, I started to notice an even fainter star in the middle of the brighter core area, first only with averted vision, later on with direct vision too, which I believe is the real central star of this planetary.

NGC 6891 (Planetary nebula)
Right ascension: 20h 16m Declination: 12° 44'
Constellation: Delphinus
Date/time: 2009.08.20 23:45 UT
Equipment: 12" f/5 Newtonian
FoV: 13' Magnification and filter(s): 250x + UHC-S filter(s)
Seeing: 5/10 Transparency: 5/5

A very tiny but bright planetary nebula, which looks pretty much star-like at small powers, but above 100x it starts to show some dimensions, looking like a blurred star. At 250x it seems quite large, without a filter it has some nice bluish colour. With an UHC filter and especially with averted vision its diametre grows even larger. Because of its small size it's very hard to discover any details, but by the time it looks as if the core has some tiny horn eastwards. SQM reading: 21.01 m/arcsec^2 9°C.

NGC 2392 (Planetary nebula)
Also known as: Caldwell C39, Herschel H45-4, Eskimo or Clown Face Nebula
Right ascension: 7h 30m Declination: 20° 53'
Constellation: Gemini
Date/time: 2010.02.21 20:00 UT
Equipment: 12" f/5 Newtonian
FoV: 11' Magnification and filter(s): 300x + UHC filter(s)
Seeing: 7/10 Transparency: 3/5

I've sketched this planetary about a year ago, but obviously I did not mark it as "SKETCHED" in my list of objects, so the result is a new drawing. However, when I compared the two sketches, it was obvious to make this mistake, because now - even if conditions were not ideal thanks to the 50% Moon nearby - I was able to see and record much more details: the brighter arcs around the central star were not at all visible for me, but now they were easily noticeable. The UHC filter was not neccessary to observe this object, however it boosted the intensity of the brighter central bubble.
