NGC 2371-2 is a dual lobedplanetary nebula located in theconstellationGemini. Visually, it appears like it could be two separate objects; therefore, two entries were given to the planetary nebula byJohn Louis Emil Dreyer in theNew General Catalogue, so it may be referred to as NGC 2371, NGC 2372, or variations on this name.[1] It has also been called thedouble bubble nebula.[2]
The central star of the planetary nebula has aspectral type of [WO1], indicating a spectrum similar to that of anoxygen-richWolf–Rayet star.[3]
NGC 2371-2 is in the constellation ofGemini which is visible in thelatitudes between +90° and −60°. Theplanetary nebula appears southwest of Castor, and is located at a distance of 4400light years.
At 13th magnitude, this nebula is well within the limits of most amateur telescopes. Like mostplanetary nebulae, this one responds well to both high magnification and narrow-band filters, especially an OIII emission filter. It is listed within the RASC's 110 Finest NGC List.[4]
