H-NGC7062
Open Cluster in Cygnus
About
Cygnus holds this modest open cluster, which lies some 4,800 light-years from us; WEBDA puts its age near 300 million years. Its stars form an irregular, roughly diamond-shaped group with a bright star at each end. It is in the Herschel 400.
Imaging tips
- About 7′ across, so it fills a third to half of the frame at 3460–5770 mm on APS-C.
- One imager shot it with a 14-inch f/10 telescope: luminance 4×10 min, red-green 2×10 min and blue 4×10 min.
- In that image the stars thin out toward the east, which the imager blamed on LDN 980, a dark nebula southeast of the cluster and outside the frame.
- Two bright stars bracket the cluster, and a deep-sky catalogue cited by one observer lists at least 8 δ Scuti variables in it.
- Best in July and August; it passes almost overhead, peaking near 86° from 50°N.
