It is unbelievable the faint stars that had been captured in this deep picture. Emanuele Colognato from Toronto, Canada, got it using a TEC 140 apochromatic refractor telescope and adding 15 subframes of 2 minutes each. He captured every detail of M3 with a high resolution CCD camera, SXVF-M25C. Definitely, nice work.
