Cygnus, the Swan is identified with Cycnus, the son of Mars, was transformed at the river Padus and transported to the sky.

Deep Sky Objects

(PAS Catalog)

M-29

 null

M-39

 M-39 Through binoculars, this open cluster is very impressive. It is large and bright and stands out well from the background. I see it as having an overall triangular shape. Through a telescope, it loses some of its impact, because of its size and the fact that it is not very concentrated to the center.

This small open cluster is seen through binoculars as a diamond shaped grouping of about 6-8 stars in a nice field. In a telescope, the count increases to about 15 sparsely concentrated stars.
