The sketch at left records M35's appearance at 36X in my 10-inch Newtonian. M35 is an open star cluster sitting at the feet of the twins, 2.3 degrees northwest of 3.3 magnitude Eta Geminorum. The cluster has an integrated visual magnitude of 5.1 and covers an expanse of nearly 30 arc minutes. But this is not our focus. NGC 2158 is. NGC 2158, also an open cluster, resides less than half-a-degree southwest of M35. This 8.6 magnitude cluster appears as a fuzzy patch about 5' across in my drawing. The smaller NGC 2158 is believed to have about twice as many stellar members as M35. Its smaller, fainter appearance is due to being more than four-times as far from Earth as the Messier cluster.
