OBJECT DESCRIPTION AND IMAGE SESSION

NGC 2610 is a very small but rather bright planetary nebula. Located in the western side of Hydra close to the border of Puppis. This nebula has a high electron temperature from 20.000 K to 18.000 K as we go from near the center to the hedge of the outer shells. Due to its characteristics this object is use to test photoionization codes which are important to measure interstellar extintion.

German-British astronomer William Herschel saw an object in December 1785 using a 18.7 inches telescope. He descibed as "...a small star with a brush south preceding, faint, small." John Herschel cataloged it in 1833 in his Slough catalogue as h 513 and noted: "...a star 14 mag with a fan-shaped brush 15" length to the south preceding side.
