C/1995 O1 Hale - Bopp on February 7, 1997 near open cluster M 71 in Sagitta

This image was taken several hours after the ion tail of the comet passed the open cluster M 71 in Sagitta (Arrow) constellation. This star cluster is the small foggy object which is placed above the comet head on the right side of the ion tail.
Another image taken on the same night with significantly longer exposure I processed in order to enhance more the ion tail of the comet.
