imaged Proxima Ophiuchi (Halifax)

The Burke-Gaffney Observatory robot imaged Barnard's Star. This star in Ophiuchus is known to have very high proper motion, approximate 10 arcseconds per year. Aimed at HIP 87937; the image is centred there. Barnard's Star is the bright star above centre.

Barnard's Star in luminance in 2021

Luminance only, 3 seconds subexposures, 12 stacked shots. FITS Liberator, GIMP. North is up; east is left.

I requested this target three times now. Previously imaged the red dwarf in 2020 and 2019.

Even with two frames, it was a enough to see the rapid motion in a little movie.
