This seems to be a double star, presumably at least one of which is very red;
but these seem to be rare on the images, so I tagged it, in case it is something
more reelevant, such as a very distant galaxy being imaged.

The red object is indeed a star from our galaxy. These images are heavily processed, so these colors are not real.

A double star (red+blue) does look pink or magenta. See Galaxy Zoo, Spectroscopic binaries
