Description:
x25 (40 mm) fills the field. More impressive
 with a pair of 10 x 50s. It is compact, 
looking like "half of M 44" without the 
greenish tinge of M 44. To W slightly are
 two interesting smudges, if you view only 
five or so stars in M39 to the E using the
 same lens with a Deep Sky attached. I count
 14 stars all of about the same + magnitude.
