NGC 4414 (Galaxy)
Right ascension: 12h 27m Declination: 31° 9'
Constellation: Coma Berenices
Date/time: 2012.04.27 22:15 UT
Equipment: 12" f/5 Newtonian
FoV: 24' Magnification and filter(s): 167x
Seeing: 4/10 Transparency: 2/5

The conditions are not ideal for observing galaxies this night as theres a strong humidity in the upper atmosphere, the Moon is just disappearing over the horizon, making some of the clouds and contrails shine. This small, bright galaxy however appears to be a very easy target. Has an almond shaped central area nearly developed into a star-like core. The Southern part of the galaxy seems to be noticeably larger than the Northern side, almost round compared to that.

SQM reading: 21.02 m/arcsec2, 7°C.

M64 (Galaxy)
Also known as: Black Eye Galaxy
Right ascension: 12h 57m Declination: 21° 37'
Constellation: Coma Berenices
Date/time: 2012.04.26 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 36' Magnification and filter(s): 100x
Seeing: 4/10 Transparency: 3/5

The well known M64 or Black Eye Galaxy (sometimes mentioned as Black Eye Nebula) is a fine specimen of large and bright Messier galaxies (although Charles Messier didn't know what galaxies were). It has a tiny star-like central core with a noticeable bulge around it, and a thin dark patch of dust lane to the NE of the core. This feature is not easily visible. On the major axis of the ellipse I can detect signs of spiral arms on both sides of the core.

SQM reading: 21.44 m/arcsec2, 6°C, light wind.

NGC 4567 + NGC 4568 + NGC 4564 (Galaxy)
Also known as: The Siamese Twins, Butterfly Galaxy
Right ascension: 12h 37m Declination: 11° 17'
Constellation: Virgo
Date/time: 2012.04.26 22:15 UT
Equipment: 12" f/5 Newtonian
FoV: 25' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 3/5

I belive this duo of galaxies is probably the most remarkable member of the enormous Coma/Virgo supercluster of galaxies. The FoV is dominated by the two interacting galaxies also known as The Siamese Twins or Butterfly Galaxy. They are not really bright, and with no sign of an outstanding central bulge. The third galaxy of the FoV, NGC 4564 has a similar brightness, but is much smaller than the twins.

SQM reading: 21.38 m/arcsec2, 7°C. The upper atmosphere is very humid with Venus having a clearly visible halo.

Equipment: 12" f/5 Newtonian
FoV: ' Magnification and filter(s): 71x

Almost all members of this spectacular cluster of galaxies is fairly bright, except maybe for NGC 4479 and NGC 4402. The Messier galaxies are especially bright: M84 and M86. The galaxy NGC 4435 has a star-like core and NGC 4438 is remarkably peculiar shaped. The image is a mosaic of multiple FoV's, with a total coverage of about 1x1.5 degrees. The galaxies from left to right are: NGC 4479, NGC 4477, NGC 4473, NGC 4459, NGC 4461, NGC 4458, NGC 4435, NGC 4438, NGC 4425, NGC 4402, M86, NGC 4387, NGC 4388, M84.

Equipment: 12" f/5 Newtonian
FoV: 45' Magnification and filter(s): 71x

Very nice cluster that is well populated with faint little stars that are very identical in both brightness and colour (bluish gray), with maybe one or two brighter stars in the middle. I can notice several star paths in the cluster. Very difficult to sketch.

SQM reading: 21.06m/arcsec2, -2°C, very strong wind.

Equipment: 12" f/5 Newtonian
FoV: 42' Magnification and filter(s): 71x

At this level of magnification it fills the FoV. Huge cluster with well balanced amount of bright and fainter stars all around. Easily visible with tiny telescopes or binoculars, looks wonderful together with M36 and M37 in scopes with huge FoV.

SQM reading: 20.97m/arcsec2, -2°C, strong wind, humid air, conditions far from ideal.

NGC 1907 (Open cluster)

Equipment: 12" f/5 Newtonian
FoV: 18' Magnification and filter(s): 250x
Seeing: 3/10 Transparency: 2/5

Very near the M38 cluster lies this little gem. Often ignored as its famous neighbour grabs all the attention, but it still worth observing this tiny cluster. Dominated by some dozens of stars, but a foggy background can also be seen. The 250x power is a bit of an exaggeration, but I found this the best to see all the details.

SQM reading: 20.61m/arcsec2, -5°C, extremely humid, terrible seeing.

Very spectacular object that is easy to spot, clearly stands out from its background. Large cluster with about a dozen bright stars dominating the view. Their colours are slightly different, some of the brighter stars are strongly orange coloured. Finished just after midnight, Central European Time, so it's 12.21 already, hooray, it's my birthday! :D

Equipment: 12" f/5 Newtonian
FoV: 40' Magnification and filter(s): 71x
Seeing: 4/10 Transparency: 1/5

I've already sketched this object about four years ago, actually it was one of my first sketches. That time the sky was great, but this time I decided to put it on paper when the conditions were definitely poor. The idea behind was to simulate the night sky conditions when I last saw this object earlier this year from Budapest, our highly light-polluted capitol. So the sketch was done with a full Moon and light clouds all over the sky. SQM reading: 15.98m/arcsec2, 3°C. Dedicated to my friend Györgyi, she knows why. ;)

Splits very nicely, although at 71 it displays no signs of being a binary, but at 250x it splits with a thin slit, however the component B is sometimes still covered by the diffraction spike of component A (to the SE). At 375x this very close binary splits nicely. It shows large difference in brightness. Both is white with A a bit yellowish while B very lightly bluish. I estimate A being 6.5m bright and B 10m. Note that catalogues list B as 7.7m, but I belive visually it's MUCH fainter than that! The estimated separation is 2" with a PA of 295°. SQM reading: 21.19 m/arcsec2, 24°C, windy.

Slightly different close pair. I estimate component A (to the NW) to be 7m bright with B being about 8.5 magnitudes. Both components are white, A with a touch of blue. The estimated separation is 1.2", position angle (PA) being 125°. SQM reading: 21.2 m/arcsec2, 22°C.

Crater Gutenberg (Our Moon)

This crater catched my attention because of its weird potato shape. Being near the terminator, half the crater is in a shadow, but it shows plenty of little details especially at 375x : small domes and mountains scattered inside. Below the crater you can see two rimae originated from the nearby crater Goclenius. A spectacular view!
