Hittade en fantastisk fin djup bild fotade med en refraktor 
Helt otrolig bild. Vem är "skyldig" och med vad har den tagits?

The Abell 2151 luminance image was taken by Tony Hallas with a QSI 583ws camera using an AstroPhysics 8" APO refractor at f/8. Total exposure time was 11 hours using 33 20-minute subexposures. The image highlights the benefits of the small 5.4µm pixel in the QSI 583 when used with a shorter focal length instrument.
The color exposure time was 140 minutes each through Astrodon E-Series Gen 2 red, green and blue filters using 20-minute sub-exposures.
