After I give lectures - on almost any subject - I am often asked, "Do you believe in UFOs?". I'm always struck by how the question is phrased, the suggestion that this is a matter of belief and not evidence. I'm almost never asked, "How good is the evidence that UFOs are alien spaceships?".

M10 (Globular cluster)
Also known as: NGC 6254
Right ascension: 16h 57m Declination: -4° 6'
Constellation: Ophiuchus
Date/time: 2008.05.27 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 50' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 5/5

A large, bright globular cluster in the Ophiuchus, only 3 degrees away from M12, therefore on an ideal night, this two together may be an interesting object for binocular-owners. Splits fine to its stars, which look quite the same, with matching brightness and spectra, with a bit brighter membere here and there. Because of this homogeneousity, it reminds me on M13, although it's smaller and fainter. Towards East I've noticed two brighter arms leaving the core area, resembling the tongue of a snake.

M12 (Globular cluster)
Also known as: NGC 6218
Right ascension: 16h 47m Declination: -1° 57'
Constellation: Ophiuchus
Date/time: 2008.05.27 22:00 UT
Equipment: 12" f/5 Newtonian
FoV: 52' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 5/5

M10 and M12 of the constellation Ophiuchus are a pair of globulars nearly identical by size and luminosity. The latter is the brigher and less homogeneous: a globular that splits greatly, consisting many exceedingly bright members, which make it look more interesting than M10. It looks a little bit oval, elongated in the E-W directions. Its visible size is smaller than that of the M10, but both of them are easy targets, that can be noticed even in the 8x50 finderscope.

M13 (Globular cluster)
Also known as: NGC 6205
Right ascension: 16h 42m Declination: 36° 28'
Constellation: Hercules
Date/time: 2008.05.29 22:30 UT
Equipment: 12" f/5 Newtonian
FoV: 55' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 4/5

The famous globular cluster of the Hercules constellation, perhaps the most represented globular in the press by far. A very easy object for any type and size of telescope, with a large diameter and high surface brightness. Even its position is easy, and especially nowadays it's again greatly visible on the late evening sky (on the Northern hemisphere at least). Splits fine even with small scopes, but reveals its real face with larger aperture: a globular full of separated, lone, bright stars. Behaves well on high magnification, I've increased powers upto 250x, and it kept revealing more and more of its members. For the first look, I've noticed that it looks a bit like a huge turtle, swimming from West to East, with the globular as its shell, and four star-paths as its legs.

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 6229 (Globular cluster)

Equipment: 12" f/5 Newtonian
FoV: 19' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 4/5

A less known globular in the constellation Hercules, a quite faint object. It doesn't split even at higher magnifications, I cannot discover a single separated star in it. If I didn't know what I'm looking at, I'd think that this may be a face-on galaxy. No wonder even Herscher catalogued this object as a planetary nebula. This would be a great challenge for amateur astronomers with smaller scopes.

NGC 6210 (Planetary nebula)

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.

Equipment: 12" f/5 Newtonian
FoV: 50' Magnification and filter(s): 71x
Seeing: 5/10 Transparency: 4/5

A rather neglected globular in Hercules. I wonder why it is treated like this compared to M13, as it is very bright and spectacular, although its visible diameter is only about half of the more famous companion. Its core area even looks brighter than that of the M13, it looks less homogeneous. It behaves fine at higher powers, at 167x it looks perfectly split.

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.

NGC 6504 (Galaxy)

Equipment: 12" f/5 Newtonian
FoV: 21' Magnification and filter(s): 167x
Seeing: 3/10 Transparency: 4/5

A very faint, tiny little GX with an apparent magnitude of about 13.6-13 magnitudes. Its core is popping out strongly from the galactic plane and resembles an almond, although the Northern side of the core looks brighter, therefore it seems to be asymmetric. It demands high magnification levels. At 250x the shapes were easier to see, unfortunately because of the terrible seeing I had to step back to a lower power. Photographically it looks quite the same as NGC 4762.

Equipment: 12" f/5 Newtonian
FoV: 16' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 4/5

Tiny, faint globular cluster with four clearly separated stars on its Western side. However, I'm not sure whether they really do belong to the cluster, or they are just plain foreground stars. With averted vision several other stars can be resolved at its slightly brighter core: two of them can be seen clearly with this technique, while some others pop up here and then when the atmosphere calms down for some moments. The core, just like the globular itself is not really sphere-like, but rather looks a little bit like an onion, with the thinner part looking to the East.

FoV: 16' Magnification and filter(s): 250x

A very dim, faint globular cluster that seems to be elongated in the N-S direction. Its core brightens softly, but it refuses to split up into stars even with averted vision and it also fails to respond to increasing magnifications. The object sits in the middle of some brighter stars that form a giant V-letter, pointing to the West.

Perfectly symmetrical, sphere-like globular cluster. Cannot resolve it at all. It's a bit fainter than the nearby NGC 6517, yet it's fairly larger than that. It's located in a field that's very sparsely populated by stars, this makes finding and following it a real adventure.

NGC 6910 (Open cluster)

Equipment: 12" f/5 Newtonian
FoV: 12' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 4/5

This tinny little object is also known as the Rocking Horse cluster. The name says it all: it really looks like a little horse jumping around the space. Although it's in a quite easy position, it still is a neglected object, as when it comes to Cygnus, everyone thinks of nebulae like the Veil and its companions, and the tiny shiny planetaries. Too bad, because this cluster is a real gem! It's special features are the two brightest stars of the cluster (at the front leg and the eye), that are apparently yellow, even though their spectral class suggests a rather white colour. This optical illusion is caused by the interstellar dust that is so common through Cygnus. A very important hint: you should use a fairly high magnification when looking at this object, because it's located in a field that is rich in bright stars, which makes it harder to detect the real shape of the cluster.

Bright, small galaxy near a very yellowish star, which I captured on a surprisingly cold night that offered an excellent transparency in the early evening hours near the village of Jászszentlászló, Hungary during the Kiskun Astro Camp. Its shape is not perfectly cigar shaped, but its northwestern end looks a bit truncated. Its surface is not entirely homogeneous: next to its gradually brightened yet not star-like core it shows many little details, changes in luminosity of its surface. SQM reading: 21.24 m/arcsec^2, 12°C. The faintest field star visible directly is about 15.1 magnitudes bright, the NELM was 6.5 at this time of the evening.

Faint, diffuse globular cluster with a perfect circular shape and a core that's getting brighter only very gently. For me it was not resolveable, although it shows a faint star on its southern side, that may be a part of the cluster. Unfortunately the Jászszentlászló sky that was excellent this far was now ruined by the quickly increasing humidity in the air. Fortunately meanwhile this happened, the seeing got much better, so it made me a little happier on this almost Winter-like night. SQM reading: 21.20 m/arcsec^2, 9°C.

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.

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.
