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.

By constellation:



NGC 7250 + SN 2013dy (Galaxy)
Right ascension: 22h 19m Declination: 40° 38'
Constellation: Lacerta
Date/time: 2013.07.21 01:00 UT
Equipment: 12" f/5 Newtonian
FoV: ' Magnification and filter(s): 300x
Seeing: 7/10 Transparency: 2/5
SQM: 20.01 m/as2 Temperature: 11°C
Humidity: dry Wind: none
Sight: 1 - nothing spectacular
Difficulty: 5 - almost invisible, total dark adaptation, very dark skies and averted vision is a must to see the object
Position: 4 - hard, complex starhopping needed
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

The host galaxy of the supernova SN 2013dy, NGC 7250 appears as a very faint patch of light in the FoV. I try to compensate for the bright sky background by increasing the magnification, caused by the rising full Moon and the dust in the air caused by harvesters. Yesterday my observation was negative, but today I succeeded, although it was still a very difficult task. I estimate the brightness of the supernova to nearly 12.3m visually.
