Overview
FSR 1419 is a rich, loose object of intermediate C3 quality. Its parallax locates it at a very large distance, well below the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, old cluster, but with a large variance across recent sources for the age and mass parameters (see Parameters). It is moderately studied in the literature.
Note: This object contains blue stragglers according to at least one source.

A poorly studied cluster first reported in Froebrich 2007. The CMD shows a scattered TO at G~19, with BSS candidates and possible binaries near the top of the main sequence, and a grouping of stars at G~16.5 consistent with a RC. ASteCA gives an age of ~4 Gyr and a distance of 9.2 kpc. CG20 reports 11.1 kpc and 1.6 Gyr; MWSC gives 8.4 kpc and 0.2 Gyr. The ASteCA distance falls between these, while the age is substantially larger than both databases.
