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 1600 pixels, and saved under "Save for Web & Devices".
