In 1976 and 1977 Sandqvist and collaborator Lindroos produced a catalogue of Southern hemisphere dark nebulae. These are now known as the Sandqvist objects.[1] Under IAU Recommendations, they are identified as "Sandqvist NNN", though at times they have also been listed as "SL", "SLDN" and "SDN NNN".

The initial list (1976) detailed 42 objects, (Sandqvist 1 through to Sandqvist 42. In 1977 a further 95 objects were added (Sandqvist 101 through to Sandqvist 195).
