NGC 2903 Galaxy in Leo

NGC2903 is a 9.7mag bright and  12′.6 × 6′.0 sized barred-spiral-galaxy (type SB(s)d) in the constellation of Leo.Even in small telescopes it´s easy to detect but is suprisingly not noticed in Messier´s catalog.

It´s distance of about 30 Mio.light-years allows us to detect a lot of detail in the central part of NGC2903,where intensive star creation takes place.The fine blue surrounding arms content many young,blue star clusters and also red star forming regions.

It was first seen by William Herschel in 1784.
