Distant Quasar 1158+465

Description

The images above shows the most distant object ever imaged from Tycho Brahe observatory. The quasar 1158+465 has a redshift (z) of 4.733. This may correspond to a distance of about 13 billion light years. The visual (V) magnitude is 20.2. The first image covers the entire CCD frame. The second (next page) is a detail taken from the first image. The white lines marks the quasar in both images. The observation was performed with a gibbous moon in the sky, so we expect to get better signal/noise ratio when we make an observation in a darker sky. Object: Quasar 1158+465 Magnitude (V): 20.2 Time of observation: April 4, 1999 Telescope: Celestron 14 operating at f/7.
