Overcast conditions with rain has predominated lately so it was good to see clear skies on Wednesday morning.
On cold northerly winds, around 1 o'clock in the morning, the clouds cleared and I spent some time looking towards the north to see how dim a star I could glimpse.
The image above is approximately 60° x 80°.
The bright star between the Guardians of the Pole and the handle of the Big Dipper is Thuban (α Draconis). The star a bit above it was the dimmest star seen. This star (10 Draconis) is magnitude 4.6.
Alcor, a companion to Mizar in the bend of the Big Dipper's handle, was picked up but is too close to the brighter star to make out.
