Cosmology does, I think, affect the way that we perceive humanity's role in nature. One thing we've learnt from astronomy is that the future lying ahead is more prolonged than the past. Even our sun is less than halfway through its life.

By constellation:



M45 + Moon occultation (Open cluster)
Also known as: Pleiades, NGC 1432, NGC 1435
Right ascension: 3h 48m Declination: 24° 12'
Constellation: Taurus
Date/time: 2010.02.21 19:00 UT
Equipment: 12" f/5 Newtonian Scope
FoV: 1° 1' Magnification and filter(s): 45x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

I was very fortunate that we had a clear night when this rare event occured, we had only a couple of such evenings this winter sofar. The 50% Moon was on the Southern side of the Pleiades. The star you may notice near the Moon was visible only for about 5-10 minutes, before it was covered by our little brother.

Copernicus crater (Our Moon)
Also known as: Copernicus + Fauth + Gay-Lussac
Right ascension: h m Declination: ° '
Constellation:
Date/time: 2009.12.26 17:15 UT
Equipment: 12" f/5 Newtonian
FoV: ' Magnification and filter(s): 250x + 30% neutral filter(s)
Seeing: 4/10 Transparency: 1/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This is my first ever Moon-sketch, displaying craters Copernicus, Fauth and Gay-Lussac with some other sub-craters and domes not noted on the sketch. This is my actual sketch done at the eyepiece, no alterations were made after manually or digitally, other than resizing. It took about 45 minutes to finish, and I'm quite satisfied with it, althouth I've found that sketching the Moon is indeed very hard and very different from sketching deep space objects. Perhaps I should not finish Lunar sketches at the eyepiece but create only drafts with different markings for different shades and create the actual sketch in the warmth of the room. As an additional difficulty, the sky was 100% covered with a thin layer of cloud which made the image to be in constant change, only 1 or 2 stars was visible here and then. Moon phase was about 69%.

Prinz crater + Montes Harbinger (Our Moon)
Also known as: Prinz, Krieger C, Vera, Angström, Montes Harbinger, Rimae Prinz
Right ascension: h m Declination: ° '
Constellation:
Date/time: 2010.03.26 20:00 UT
Equipment: 12" f/5 Newtonian
FoV: ' Magnification and filter(s): 300x + 15% neutral filter(s)
Seeing: 2/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

I was just cruising around the terminator of the Moon, testing the new cooling equipment on my OTA, when I found a very interesting mountain chain with some ruined crater at one end, near the crater Aristarchus which was right on the terminator. The view was so spectacular, that I decided to make a sketch. I found out that the large crater was Prinz, and the mountains attached are Montes Harbinger. I've sketched some additional minor craters nearby that have been cropped out from this image. A really unusual view, worth taking a peek when it's near the terminator!

Crater Gutenberg (Our Moon)
Also known as: Crater Gutenberg, Rimae Goclenius
Right ascension: h m Declination: ° '
Constellation:
Date/time: 2011.08.17 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: ' Magnification and filter(s): 167x
Seeing: 6/10 Transparency: 2/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

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!

Full Moon (Our Moon)
Right ascension: h m Declination: ° '
Constellation:
Date/time: 2015.07.31 22:00 UT
Equipment: 4.5" f/8 Newtonian
FoV: ' Magnification and filter(s): 45x + Polarizing filter set filter(s)
Seeing: 6/10 Transparency: 2/5
Humidity: high
Sight: 4 - lots of details, very interesting, unique look
Difficulty: 1 - instantly visible, no dark adaptation or averted vision needed
Position: 1 - very easy, many bright stars nearby
Location: Lipótfa, Zselic, Hungary
Observer: Ferenc Lovró
Description:

Our Moon at its (nearly) fullest. This observation was made after a rainy day, so the atmosphere was soaking wet, making the Moon lit the whole entire night sky. As this was making virtually any deep-sky observation impossible, I decided to sketch the Moon. It took about an hour or more, and turned out to be an extremely difficult quest. Although there were many tiny details visible in my telescope, it is just impossible to sketch them all with the low resolution that rather small FoV circle of my observation log sheet permits. Small white dots, little domes and mountains, tiny bays... just can't sketch them all.
