Messier 55 Globular Cluster in the south of sagittarius. A faint blob, surprising it was in reach of the limited kit being used.

 

121 x 1 second exposures.

 

Camera was a 1004x-JG modified video camera on a fixed tripod and ball head. 135mm F2.8 M42 screw thread lens stopped to F4. No filters. Camera in gamma mode 1 (highest internal DSP gamma stretching) and gain 75%.
