Both open cluster in one field. The following description suits to both.
Faint but clear with direct vision, moderately concentrated, only a few
faint stars. To find them I pointed my scope to Omikron2 Orionis which
forms a square with three other quite bright stars. From there I hopped
via 11 and 15 Orionis to SAO 94377. The clusters are located immediately
north of it.
