imaged 70 Oph for 2023 (Halifax)

That time of year, again.

Asked the Burke-Gaffney Observatory to image the fast-moving binary system 70 Ophiuchi.

I submitted the request on 18 May.

Again, I commanded the robot to centre on the field star GSC 0043402340.

Luminance only, ½ second subexposures, 20 stacked shots. FITS Liberator, GIMP. North is up; east is left.

The sky conditions, for a change, were really good. The CSC showed cloud: clear; ECMWF: clear sky trans: transparent; seeing: average 3/5; Moon alt.: -15.

Wow, I've had quite a run now, going back 8 years
