|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.
This is a recent (06/26/2012) scan, as I had hooked up my scanner to
capture the last few Messier film negatives for this project.
This image is a crop of a scan to file as a 5408 x 3524 pixel full frame scan of the 35mm negative.
Reduced in Photoshop to 1024 pixels, and saved under "Save for Web & Devices".
