H-NGC2567
Open Cluster in Puppis
About
A sparse open cluster in Puppis, about 5,470 light-years away, with an estimated 81 to 96 stars. It is around 500 million years old and has a metal content close to the Sun's. Herschel discovered it in 1793.
Imaging tips
- Small at about 10′, so use 2,420–4,040 mm on APS-C or 3,710–6,190 mm on full frame for it to fill a third to half of the frame.
- At 21 mag/arcsec² it is not a faint target, but the cluster is sparse, with only 81 to 96 stars estimated.
- A student project built a colour image from 15 frames through B, V and R filters, with total exposures of 70, 40 and 20 seconds.
- Best in January and February; it peaks near 9° from 50°N, so it needs a low southern horizon.
