Caldwell 49 – The Rosette Nebula (Narrowband)

Caldwell 49 – The Rosette Nebula (Narrowband)

with No Comments

5,000 light years away, the Rosette Nebula is striking in both narrowband and visible light (where it is primarily red in color).  Because of its large size, only small magnification is necessary to capture the nebula and visually, the central cluster is easy to see.  The central area houses cluster NGC2244 and NGC2237; the bright cluster of hot, young stars illuminates the gas of the nebula.

14 900s Ha, 10x 1200s OIII, 13x 1200s SII on a QSI683 and TAK FSQ 106, SHO Hubble palette.
