|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. See the
14.5" ccd version.
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 1024 pixels, and saved under "Save for Web & Devices".

NGC 6864 = M75 = E595-SC13 20 06 04.7 -21 55 16 V = 8.6; Size 6.0 17.5" (7/14/93): bright, moderately large, 3' diameter, round, very bright striking core 30" diameter, very mottled. Several extremely faint 15th mag stars pop in and out of view with averted vision in outer halo. A mag 14 star is in the inner region just NE of core. The cluster almost reaches four mag 12.5-13 stars which cradle the globular on the south and NE sides and a fainter star is off the NW side. - by Steve Gottlieb
