Description: I tried this object few nights ago but without success because it was plotted on the wrong place in TriAtlas. Actually I saw it then but wasn't sure that it was the object. Anyway, this time I had to hurry with the sketch because NGC 6664 was slowly sliding to behind the trees. There are five to seven stars brighter than 11 mag and about 25 fainter stars visible at 214x.
