Tombaugh 5 is a somewhat detached, moderately rich open cluster containing stars 
which vary moderately in brightness.  It is approximately 17' in size and is 
composed of about 60 stars.  I came across Tombaugh 5 serendipitously while 
observing speedy Comet Lee, which was just to north of the cluster at the time. 
Such chance encounters make amateur astronomy all the more interesting.
