This bright cluster matches well in position with No. II.6 in Lacaille's catalog of 1751-52, although it was a missing Lacaille object for a long time. From Lacaille's list, it found its was into Johann Elert Bode's atlasses and catalogs, and e.g. listed as "f 396 Argus" in his Uranographia (Bode 1801), which were then used by James Dunlop, who found it to be a cluster and cataloged it as Dun 490 (Dunlop 1828). The identity of Lac II.6 and Dun 490 was noted by Arthur Auwers in 1862 when investigating Lacaille's catalog (Auwers 1862). It was independently found by R.J. Trumpler in 1930 and cataloged as Trumpler 10.

Also visible in this image is another but more compact open cluster NGC2671 (upper left corner)

The field of view is sorrounded with filaments from Vela's SNR and other nebulae.
