Finally we shall place the Sun himself at the center of the Universe. All this is suggested by the system of procession of events and the harmony of the whole Universe, if only we face the facts, as they say, "with eyes wide open."

NGC 2281 (Open cluster)
Also known as: Cr 116
Right ascension: 6h 48m Declination: 41° 5'
Constellation: Auriga
Date/time: 2008.01.24 19:30 UT
Equipment: 12" f/5 Newtonian
FoV: 15' Magnification and filter(s): 167x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This open cluster can be located easily, yet it doesn't cover a large area. It has half-dozen brighter and at least 20 fainter members. Its most notable pattern is the diamond made up by four bright stars in the middle of the cluster. The OC is clearly separated from its environs.

Stock 10 (Open cluster)
Right ascension: 5h 39m Declination: 37° 56'
Constellation: Auriga
Date/time: 2008.02.12 18:00 UT
Equipment: 12" f/5 Newtonian
FoV: 52' Magnification and filter(s): 45x
Seeing: 7/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

If I wouldn't check this object out previously with my planetarium-software, I would most probably didn't even notice this sparsely populated open cluster through the telescope. Catalogues claim that it has a diameter of around 25', however it looks larger to me. Its three brightest 7m members rule the field of vision. Unfortunately at the time of this sketch, the Moon was in a phase of around 35%, painting the entire sky gray, which is probably the reason why I haven't noticed any stars brighter than 13m in the area even by using averted vision, no matter that there were an excellent seeing this time.

NGC 2126 (Open cluster)
Also known as: Herschel H68-8
Right ascension: 6h 3m Declination: 49° 52'
Constellation: Auriga
Date/time: 2010.02.21 19:30 UT
Equipment: 12" f/5 Newtonian
FoV: 25' Magnification and filter(s): 100x
Seeing: 6/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

A small, triangle shaped open cluster sitting in a sparse stellar environment. A very bright star dominates the cluster at one of its corners, but I suspect that this star is not actually a part of this group. Apart this, the cluster shows about a dozen of brighter and another dozen of fainter members.

3C 147 (Quasar)
Also known as: PGC 2355407
Right ascension: 5h 43m Declination: 49° 40'
Constellation: Auriga
Date/time: 2010.02.15 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 34' Magnification and filter(s): 100x
Seeing: 7/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

This is actually an unsuccessful observation, I still believe it should be posted here because it shows how hard is the life of an ordinary visual observer. :) The map I'm using (Triatlas B) shows stars and DSO's to approximately 12 mags. I found this quasar in Auriga and I was sure I'll be able to take a glimpse of this distant object. Without exact position data, I decided to sketch the field of stars and identify the actual quasar later. Unfortunately my astronomy program did not show any quasar here to the 16.5 magnitudes. The reason is that it lists the quasar at 18.2. I've googled the Vmag of this QSO, and found brightness data anywhere from 15.0 to 17.8m. At 15 magnitudes I should be able to see the object surely with averted vision (we had 100% snow coverage, so the NELM was not as good as it used to be). So, what I've learned from this is that brightness information must be handled with special care, especially for faint and exotic objects.

M36 (Open cluster)
Also known as: NGC 1960
Right ascension: 5h 37m Declination: 34° 9'
Constellation: Auriga
Date/time: 2011.12.20 22:00 UT
Equipment: 12" f/5 Newtonian
FoV: 42' Magnification and filter(s): 71x
Seeing: 2/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

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

SQM reading: 20.82m/arcsec2, -6°C, slightly humid weather with NELM getting worse by every moment.

NGC 1907 (Open cluster)
Right ascension: 5h 29m Declination: 35° 20'
Constellation: Auriga
Date/time: 2012.01.18 23:00 UT
Equipment: 12" f/5 Newtonian
FoV: 18' Magnification and filter(s): 250x
Seeing: 3/10 Transparency: 2/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

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.

M38 (Open cluster)
Also known as: NGC 1912
Right ascension: 5h 30m Declination: 35° 52'
Constellation: Auriga
Date/time: 2012.01.20 22:45 UT
Equipment: 12" f/5 Newtonian
FoV: 42' Magnification and filter(s): 71x
Seeing: 3/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

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.

M37 (Open cluster)
Also known as: NGC 2099
Right ascension: 5h 53m Declination: 32° 33'
Constellation: Auriga
Date/time: 2012.01.20 23:30 UT
Equipment: 12" f/5 Newtonian
FoV: 45' Magnification and filter(s): 71x
Seeing: 3/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

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.

UU Aurigae (TVICS)
Also known as: UU AUR
Right ascension: 6h 37m Declination: 38° 26'
Constellation: Auriga
Date/time: 2013.02.28 18:20 UT
Equipment: 12" f/5 Newtonian
FoV: 16' Magnification and filter(s): 250x
Seeing: 7/10 Transparency: 3/5
SQM: 21.03 m/as2 Temperature: 5°C
Humidity: low Wind: none
Sight: 3 - definite details, interesting look
Difficulty: 1 - instantly visible, no dark adaptation or averted vision needed
Position: 3 - moderate, some starhopping needed
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Nice bright variable carbon star. I can see its orange/red colour instantly, its tone reminds me of the colour of yolk. A nice one.

NGC 1664 (Open cluster)
Right ascension: 4h 52m Declination: 43° 42'
Constellation: Auriga
Date/time: 2014.03.08 20:45 UT
Equipment: 12" f/5 Newtonian
FoV: 36' Magnification and filter(s): 100x
Seeing: 7/10 Transparency: 2/5
SQM: 17.95 m/as2 Temperature: 6°C
Humidity: moderate Wind: gusts
Sight: 4 - lots of details, very interesting, unique look
Difficulty: 3 - moderately visible, dark adaptation needed, averted vision might add to details
Position: 1 - very easy, many bright stars nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Faint, large open cluster with member stars of very similar brightness. Sparsely populated, yet it features many spectacular stellar paths. A really nice object, should make a great target on a better evening. In the Eastern corner of the FoV I can see a really nice, perfectly square pattern of stars. The Half Moon is near the Auriga constellation, and sometimes stormy wind gusts make observation harder.
