xi Boo round 2 (Halifax)

Back on 22 May 2019, I imaged ξ (xi) Boötis or Σ1888 for the first time. It is a binary with a 151+ year orbit. Maybe through annual images I'll be able to see the orbital motion. This is the year 2 shot...

double-star xi Bootis in luminance

Luminance only, 0.5 seconds subexposures, 12 stacked shots. FITS Liberator, GIMP. North is up; east is left. Centred on SAO 101256.

I'll try blinking it but I suspect it will be difficult to detect any movement at this stage...
