Abstract:
CCD B,V observations on the NGC 7142 (1950 position 21h44.7 +65d34')
field reveal the presence of a single short-period variable star.
The color-magnitude diagram of the field shows evidence for small-scale
variable absorption across the face of the cluster. The age of NGC 7142
appears to be confirmed as intermediate between that of M67 and NGC 188,
and a new distance-modulus is found to be (m-M)0 = 11.4 ± 0.9
