Comments ... This 6" lens continues to Astound me.
... Don't count the stars, instead I dare you to count all the Galaxies in this image.
... This image is centered on the upper of the two bright galaxies, NGC4884 at 12.5mag.
... Abell 1656 in Coma Berenices is 321-400 Million Light Years distant.
... Quasar HB89(1256+280) is 21.0mag, its RedShift is 2.66, making it 10.865 Billion Light Years distant.
... NED image of Quasar , it is the small dot in the exact center.
... (NED Source = NASA/IPAC Extragalactic Database)
... There two Galaxy Tidal Tails:
... ... 1) the largest is lower right of NGC4874, at 12.9mag, which is the lower bright Gx in the center of the image.
... ... 2) to the upper left of NGC4911, at 13.6mag, below and left of the nice spiral NGC4921, at 13.8mag.
