Steve's Notes
=====
NGC 6537
17.5" (8/17/01): picked up at 220x as a fuzzy mag 12 "star" forming the eastern vertex of an obtuse, isosceles triangle with two similar stars 1.5' W and 2.4' NW. Excellent view at 380x and 500x. Clearly nonstellar at the higher powers, ~5" diameter with a bluish color and occasionally a slightly brighter center.
13" (8/17/85): appears mag 12.0 or fainter with OIII filter at 79x. In the field SW of a mag 7 star forming the southern "star" of an arc of three stars.
13" (8/11/85): stellar at 166x, estimate mag V =12.5. Just non-stellar at 220x and clearly nebulous at 360x, about 4" diameter. Appears fainter than computed V magnitude. Located 7' SW of mag 6.8 SAO 161056 and forms the east vertex of an obtuse triangle with two mag 12 stars 1.5' WNW and 2.4' NW.
