I tried a completely different processing style... and i was very pleased at the results. Enjoy !
NGC 2903 is an isolated
barred spiral galaxy in the
equatorialconstellation of
Leo, positioned about 1.5° due south of
Lambda Leonis.
[10] It was discovered by German-born astronomer
William Herschel, who cataloged it on November 16, 1784. He mistook it as a double
nebula, as did subsequent observers, and it wasn't until the nineteenth century that the
Third Earl of Rosse resolved into a spiral form.
[5]J. L. E. Dreyer assigned it the identifiers 2903 and 2905 in his
New General Catalogue; NGC 2905 now designates a luminous knot in the northeastern
spiral arm.
[11]This
field galaxy[12] is located about 30
[3] million
light-years away from the
Milky Way, and is a member of the
Virgo Supercluster.
[4] The
morphological classification of this galaxy is SBbc,
[6] indicating a barred spiral (SB) with moderate to tightly-wound spiral arms (bc).
De Vaucouleurs and associates assigned it the class SAB(rs)bc, suggesting a weaker bar structure (SAB) with a partial ring (rs). The bar structure appears stronger in the
near infrared band. The galaxy as a whole is inclined by an angle of 60° to the line of sight from the Earth.
[7]72% of the stellar mass is located in the outer disk of the galaxy, and 20% is found in the bar. The bulge adds 5% of the stellar mass, and its star population is generally older.
[13] However, the central ~650 pc radius volume of the core is a strong
starburst region. The
star formation rate here is 0.7
M☉ y−1 and it is being fed by gas inflow along the bar. There is no evidence of an
active nucleus.
[7]The irregular
dwarf galaxy KKH 51 appears to be a companion, as they have an angular separation of 25
′ and nearly the same
radial velocity.
