Open Cluster in Monoceros
About
A small, faint open cluster in Monoceros, about 1° north-east of Collinder 106. SIMBAD gives it a visual magnitude of 7.0 and no angular size.
Imaging tips
- Listed as only a few arcminutes across, it is too small to frame: use a long focal length and a fine pixel scale.
- Broadband is the right choice for an open cluster.
- Collinder 106 is about 1° away, so it falls in a wider field rather than the same frame.
- Best placed from December to January; it peaks near 47° altitude from 50°N.
