Notes: This is one of the Messier objects not currently 'visible' from my Thousand Oaks observatory ... In an effort to 'fill in' my Messier images page, I will post what film images I have. My film scanner is not presently hooked up, so I am using scans made for my old film website from the early 2000's.

Most of the film scans from the 14.5" f5 Newtonian reflector were centered on the object of interest, and were generally scanned to file as a 2000 x 2000 pixel crop of the 35mm negative.

Reduced in Photoshop to 1600 pixels, and saved under "Save for Web & Devices".

V = 6.8;  Size 13.5

17.5" (6/3/00): bright, moderately large globular, ~6'x4.5' (elongated N-S) with 
a bright 3.5' core.  The cluster is breaks up several dozen stars at 220x but at 
500x at least 50 stars are resolved over the entire face of the globular.  There 
are a couple of strings of stars on the SE side of the halo with a dark lane 
between the strings.  The brightest star is on the NE side.

13": bright, elongated N-S, very mottled, brighter core.  The outer edges barely 
resolve into one or two dozen stars at 220x.

8": lively, two or three very faint stars are resolved at the north edge.
