NGC 676

Galaxy in the constellation Pisces

NGC 676 is a lenticular[6] Seyfert 2 galaxy[4] about 18.7 Mly away in the constellation Pisces.[2] It can be seen near the star α Piscium.[6] Located close to the celestial equator, it is visible from both hemispheres.[6] BD +04 0244, a star with a visual magnitude of 10.44, is superposed 5.1 arc seconds south-southwest of the nucleus.[2] It is one of the 621 galaxies described in Marat Arakelian's catalog of high-surface-brightness galaxies.[5]

Unusual appendages around bright stars are commonplace, but never seem to be mentioned. What are they? First, a telescope brings starlight falling over a large area to a small area. To get at this small area, however, one must go inside a reflecting telescope, and one good way to do this is to use support rods, which are right in the view of the telescope. The wave nature of light causes it to deflect when passing near these rods. Light scatters away from the original destination point ending up elsewhere and appearing as "diffraction spikes". These annoying spikes steal precious light from the central image and hide light from fainter, more interesting stars.
