We are probably nearing the limit of all we can know about astronomy.

My astronomy sketches. Hover mouse over image for the inverted look. For fainter objects, take a look at the black-on-white original, sometimes it reveals more details.

By constellation:



C/2009 K5 (McNaught) (Comet)
Also known as: Comet McNaught K5
Right ascension: 22h 40m Declination: 79° 31'
Constellation: Cepheus
Date/time: 2010.05.10 22:00 UT
Equipment: 12" f/5 Newtonian
FoV: 13' Magnification and filter(s): 100 x
Seeing: 6/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Even the finderscope displays this comet like a very faint spot. At 100x it shows a very nice occultation with two brighter stars. Very nice gradient change in its brightness, slightly oval shape, bright but tiny core. A very small diametre of about 1.2'.

C/2009 K5 (McNaught) (Comet)
Right ascension: 23h 21m Declination: 81° 10'
Constellation: Cepheus
Date/time: 2010.05.12 23:30 UT
Equipment: 12" f/5 Newtonian
FoV: 25' Magnification and filter(s): 100x
Seeing: 6/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

The comet is easy to find in the finderscope as a very faint spot. Nice gradient change in its brightness, definitely oval shape, bright and tiny core. The diametre looks much larger than two days ago, perhaps this is because of the better atmospheric conditions. I estimate a size of about 2.5' x 1.9'.

C/2009 P1 Garradd (Comet)
Right ascension: 21h 20m Declination: 13° 55'
Constellation: Pegasus
Date/time: 2011.08.05 20:00 UT
Equipment: 12" f/5 Newtonian
FoV: 38' Magnification and filter(s): 100x
Seeing: 7/10 Transparency: 4/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Fairly bright comet, with a tail to the SSE and a tiny sharp extension to the S. The sketch displays the comet's position at the beginning of the observation while the crosshairs define the position about 45 minutes later when I finished the sketch. SQM: 21.42, 13°C, bit humid.

168P / Hergenrother (Comet)
Also known as: Comet Hergenrother, 168P
Right ascension: 0h 0m Declination: 25° 41'
Constellation: Hercules
Date/time: 2012.10.08 22:10 UT
Equipment: 12" f/5 Newtonian
FoV: 24' Magnification and filter(s): 167x
Seeing: 4/10 Transparency: 2/5
SQM: 21.06 m/as2 Temperature: 5°C
Humidity: low Wind: breeze
Sight: 3 - definite details, interesting look
Difficulty: 4 - hardly visible, dark adaptation and very dark skies needed, averted vision is required to see details
Position: 2 - easy, bright star nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Surprisingly bright comet, its cone shape can be noticed even with the smallest magnification. Its a rather large object, by increasing power and especially by using averted vision its N-S elongated tail becomes more and more spectacular, can be separated to three definite parts: on its Western border a longer tail can be seen, in the middle a little but bright cone can be noticed and finally to the South I can see another brighter filament that's not as spectacular like the two others. Unfortunately it's not easy to observe this bright object this time, because thin clouds are going by, sometimes completely covering Alpha and Beta Herculis.

C/2014 Q2 (Lovejoy) (Comet)
Right ascension: 3h 36m Declination: 12° 07'
Constellation: Taurus
Date/time: 2015.01.13 21:35 UT
Equipment: 12" f/5 Newtonian
FoV: 2° 15' Magnification and filter(s): 50x
Seeing: 6/10 Transparency: 4/5
SQM: 21.16 m/as2
Humidity: dry Wind: none
Sight: 5 - plentyful of details, a must see object, jaws dropped
Difficulty: 2 - easily visible, some dark adaptation needed, averted vision might add to details
Position: 2 - easy, bright star nearby
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Comet C/2014 Q2 (Lovejoy) is at its brightest, therefore it's easily visible with your unaided eyes in the constellation Taurus the Bull. With bare eyes it resembles M44 only brighter. With my telescope it reveals many details in its curvy tail which I can follow for about 2 degrees. The head or coma of the comet is oval, or a little bit egg shaped. The core is bright, looks like an out-of-focus star. Just beautiful! The sketch is a mosaic of about two fields.
