NGC 925

Telescope: Planewave 17" CDK reflector, 1940 mm FL
Camera: FLI-PL6303E, 3072 x 2048 pixels
Exposure: Lum:11 x 3m RGB:4x3m each, 2x bin. Plus a 10 minute HA layer from the Kitt Peak 2.1m. Processed with PixInsight.
Location: Mayhill, New Mexico (Elevation 7380')
Image Center (J2000): RA 2h 27m 17s, Dec 33° 34' 34"
Image Size: 25' x 23'

Nearly face-on barred spiral galaxy, about 9' x 5' in this image, with asymmetrical spiral arms and a bar offset from the center of the galaxy. Many H II regions have been identified in NGC 925. Cepheid variables have been identified in NGC 925 but are too faint for this image. Part of the NGC 1023 group of about 30 galaxies which includes NGC 891. The dynamic range in the image was reduced to enhance the galaxy's central detail.
