In 1915, British astronomer Philibert Jacques Melotte, (1880-1961), at the Royal Greenwich Observatory, created a catalog of 245 deep sky clusters as part of a astrographic study of a early photographic atlas of the sky based on plates taken at Johannesburg, South Africa, and Godalming, England.
Mellotte also discovered in 1908 the eigth moon of Jupiter, today known as Pasiphae, and also asteroid 676 Melitta in 1909.

The Melotte catalogue contains both open and globular clusters. The amateur astronomer will find many of his 'Melotte' objects listed on star atlases and observing guides. While some of the 'Melotte' objects are unique objects, such as Mel111 - the Coma Berenices cluster, the majority are already listed under other prior catalog designations such as 'M', 'NGC', or 'IC'. Melotte clusters also cover a wide range in brightness and size, and can be found all along the Milky-Way, with several large bright members located in Perseus and Taurus.

On the left side of the webpage is my personal observation list of the
'Melotte catalog of star clusters'.

I currently have all 182 objects visible from my Pittsburgh, PA latitude of around +40.
(63 of the '245' objects are not observable from latitude +40).
