visited Barnard's Star (Halifax)

Visited Barnard's Star with the BGO robotic system. This star in Ophiuchus shows very high proper motion. It is the brightest star, above centre. If I image it annually, I should be able to see motion against the surrounding stars. It's heading to the north.

fast-moving Barnard's Star in luminance

Luminance only, 1 second subexposures, 12 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

It's close. About 6 light-years away.

I'll try to image this annually for a few years...

Tripled the exposure time on 25 May with a better result.

Made a little animated GIF on 8 May '20.
