A.22 Deep Sky Objects

The built-in list of deep sky objects includes all open clusters down to magnitude 4.5, all globular clusters down to magnitude 6.5, all diffuse nebulae down to magnitude 6.5, all planetary nebulae down to magnitude 9.0, and all galaxies down to magnitude 9.0.

Distribution of the built-in objects is fairly uniform over the sky, with 30 objects located above the North Pole region, 30 below the South Pole region, and 50 around the equator.

The following four tables list all of the 110 deep sky objects that are built into Scientific Astronomer. The column on the far right lists three different right ascension and declination ranges corresponding to three different parts of the table. Below the right ascension and declination headings are listed any dominant constellations or stars that appear in the region.
