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 6572 (Planetary nebula)
Also known as: Blue Racquetball
Right ascension: 18h 13m Declination: 6° 51'
Constellation: Ophiuchus
Date/time: 2010.06.05 23:30 UT
Equipment: 12" f/5 Newtonian
FoV: 11' Magnification and filter(s): 300x
Seeing: 7/10 Transparency: 2/5
Location: Nádasdladány, Hungary
Observer: Ferenc Lovró
Description:

At 71x all I can notice is that a star appears in a magical deep blue colour. I had to increase magnification all the way up to 300x to be perfectly sure, that this star in fact has some extent. Due to the tiny size, the UHC filter does not help me to enhance the view at all. At 300x some tentacles appear but the whole sight is very uncertain. The object is very bright but I don't think it's any larger than 3", maybe even smaller than that. Later on I've checked some photos and I was very happy to see that those tentacles are really there, but they are visible only on the best photographs. SQM reading: 20.85 m/arcsec2, 11°C.
