Telescopes are in some ways like time machines. They reveal galaxies so far away that their light has taken billions of years to reach us. We in astronomy have an advantage in studying the universe, in that we can actually see the past.
/ Sir Martin Rees /

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:



NGC 3738 + 3756 (Galaxy)
Right ascension: 11h 37m Declination: 54° 24'
Constellation: Ursa Major
Date/time: 2011.05.06 21:15 UT
Equipment: 12" f/5 Newtonian
FoV: 32' Magnification and filter(s): 100x
Seeing: 5/10 Transparency: 3/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

Two bright but small galaxies are visible in the exepiece. Although the catalogues say that the face-on NGC 3738 is is almost 1 magnitude brighter than the nearly edge-on NGC 3756, visually the later one is clearly a lot brighter. The NGC 3738 is barely brightening near its core, and shows no star-like nucleus. The oval shaped NGC 3756 is almost perfectly even in brightness, displays no brighter parts. I notice that it's a bit asymmetric, the Western side of the ellipse is a bit flatter. SQM reading: 21.19,/arcsec2, 0°C (guess we're having a negative temperature record, where's the global warming?).
