NGC 2371-2 is a dual lobed planetary nebula located in the constellation Gemini. Visually, it appears like it could be two separate objects; therefore, two entries were given to the planetary nebula by William Herschel in the "New General Catalogue", so it may be referred to as NGC 2371, NGC 2372, or variations on this name.

At 13th magnitude, this nebula is well within the limits of most amateur telescopes. Like most planetary 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
How to findEdit
NGC 2371-2 is in the Gemini constellation which is visible in the latitudes between +90° and −60°.This nebula is easy to find because it lies southwest of Castor. Start at Castor and use the two bright stars that form an equilateral triangle to the southwest as a guide to tell you which direction to sweep. The nebula lies between the widest pair of three 7th magnitude stars that lie in a straight line. This planetary nebula is located at a distance of 4400 light years.
