DescriptionM34 was probably first found by Giovanni Batista Hodierna before 1654, and independently rediscovered by Charles Messie on August 25, 1764. <--> This is an attractive open cluster characterized by a couple of dozen giant blue stars, and a smaller number of red ones, many of which appear to be doubled. Whether these are physical or optical doubles is unclear; I suspect some of both,
