|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.
This image is a scan to file as a 2000 x 1867 pixel crop of the 35mm negative.
Reduced in Photoshop to 1600 pixels, and saved under "Save for Web & Devices".
According to "Star Clusters", by Brent Archinal and Steven Hynes, the size of this open cluster is 10 arc minutes.
