Ngc 2017

This chance grouping of stars resembles a small cluster. The disks and spikes are effects of the large professional telescope through which the picture was taken.

GAMMA (g) LEPORiS 5 A 4th-magnitude yellow star with a 6th-magnitude orange companion visible through binoculars.

KAPPA (k) LEPORiS 5 A 4th-magnitude star with a close 7th-magnitude companion, difficult to separate with the smallest apertures.

R LEPORiS 15 A variable star of the same type as Mira, noted for its intensely red color. Its brightness ranges from 6th to 12th magnitudes every 14 months or so.

M79 5 A modest globular cluster visible with a small telescope, over 40,000 light-years away and so not easy to resolve into individual stars. Herschel 3752, a triple star with components of 5th, 7th, and 9th magnitudes, lies in the same field of view.

NGC 2017 5 A compact group of stars, consisting of a 6th-magnitude star with four companions of 8th to 10th magnitudes visible through small telescopes. Larger apertures reveal three more stars. However, all these stars seem to be a chance line-of-sight grouping, so NGC 2017 is not a true cluster at all.
