DeepSky Objects

CVAS Members DeepSky Astrophotography using Telescopes and CCD and Digital Cameras.  These are typically long exposures and multiple exposures that are "stacked" and processed with software.

NGC 4631

"The Whale Galaxy"

barred spiral galaxy in the constellation Canes Venatici. This galaxy's slightly distorted wedge shape gives it the appearance of a herring or a whale, hence its nickname.

NGC2903

 is one of the more conspicuous objects that Charles Messier missed when he compiled his catalog. It was ultimately discovered by William Herschel who catalogued it on November 16, 1784 as a double nebula. In the 1800s it was resolved by the third Earl of Rosse who determined it spiral form. It's a beautiful spiral seen from an oblique angle.

The image also contains many distant background galaxies.

     Its dimension is 12.6 x 6.6 (arc min) and it's approximately 30.5 million light years from Earth with an apparent magnitude of 9. It's diameter is 100,000 light years .
