Description

A contrasting pair of open clusters in Gemini. Final image downscaled 2x.
The bluer, younger Messier 35 (~175 Myr) lies in the foreground (~4000ly). The yellowish, older (~2 Gyr) NGC2158 lies southwest of Messier 35. NGC2158 is much further (~11000ly) away and suffers from noticeable interstellar extinction/reddening.

The stars in the blue channel is bloated due to the optics of FMA230, and renders white and yellow-white bright stars pink.
