Image Infornmation: NGC 20903 is a spiral
galaxy in Leo, some 20 million light years distant. It is known for its bright blue spiral arms, large number of
star clusters and the high frequency of star formation at the center of the galaxy. In this image
a small cluster of bright globular objects can be seen at the center of the galaxy, in the midpoint of the barred section
of the galaxy. The significance of this finding is unknown to me, though it may represent areas of intense star formation.
Additional Comments: Songle Luminance channel used to produce this image, showing the central bright globular rgions at the center
of this galaxy. Minimal processing was performed, including data stretching (curves/levels in PS CS/3), deconvolution
(CCD Stack) and unsharp masking.
