Steve's Notes

===== NGC 7240 17.5" (7/15/93): faint, very small, elongated 3:2 NW-SE, weak concentration. Situated between a mag 11 star 3.0' NW and three mag 13 stars about 3' SE. Fourth in the compact NGC 7242 group. Forms a tight trio with IC 1441 1.4' NNW and IC 5192 1.7' WSW. Also nearby are NGC 7242 3.5' ENE and IC 5191 4.1' WNW. The observed elongation is probably due to superimposed mag 16 star on the southeast side. 13" (9/3/83): very faint, very small, near visual threshold. Located 3.5' W of NGC 7242 in a compact group.
