NGC2903 - Spiral Galaxy in Leo - RGB
From Wikipedia: NGC
2903 is an isolated barred spiral galaxy in the equatorial
constellation 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.
