In 1957, German astronomer Hans Haffner (1912 - 1977), working at Boyden Observatory in South Africa, (which he later became the Director of), created a catalog of "New Galactic Star Clusters in the Southern Milky Way", containing 26 open clusters. Additionally, during the 1960’s, Haffner served as chairman of the open clusters section of the IAU.
The amateur astronomer will find many of his 'Haffner' objects listed on star atlases and observing guides.

While some of the 'Haffner' objects are already listed under other catalog designations such as 'NGC', the majority are unique objects, not listed in any other prior catalog. Haffner clusters can be found along the Winter Milky-Way in Canis Major and Puppis.

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

I currently have all possible 26 objects visible from my Pittsburgh, PA latitude of around +40.
