M92 = NGC6341 (17h 17.1m +4308, 6.5 mag.)

This globular cluster was discovered by Bode in 1777 and Messier observed it on March 18, 1781. M92 is about 25,400 ly distant and contains many bright giants forming long "tentacles". Being spectacular on its own, it cannot however compete with M13 nearby. To find M92, look about 620' N of p Herculi (see finder chart below).

To create the above image, twenty five white integrations (30 sec. each) taken on July 3, 2002 from Harrowsmith, Ontario were combined with cyan, magenta and yellow-filtered exposures (3 x 120 sec. each) taken on June 28, 1998 from Sooke, BC. In both cases a Cookbook 245 LDC CCD camera was used on Ultima 8 f6.3 telescope autoguided with Cookbook 211 LDC CCD camera on a piggybacked 500mm f8 telephoto lens. AIP4WIN and Corel PhotoPaint 8 were used for image processing.
