Telescopes

Detecting the Sun in microwaves

Evan designed and built a microwave detector from off-the-shelf parts. Aimed at the Sun it emits a loud squeak, aimed at Martin, it just mewls. In the bottom-right image, Evan uses a particularly handsome 2016 Astronomy Wall Calendar to prove that the detector is not merely reacting to visible light.

Pub quiz

(top) Semi-finals. (bottom) The final round: James, Leslie and Evan. | The 2015 Spring Summer Star Party Pub Quiz Champion: James Smith! His prize ribbon is generously sponsored by ScopeX.

Sunday night, after the SSP, the die-hards relax. Chris, Lynnette, Ed, Alan & Rose | John Richards, Barry Dumas, Ed, Lynnette, Louis Fourie, Miemie D., Rose, Chris and Alan.

Some SQM-L readings

I used Ed's SQM-L to measure the sky brightness as twilight progressed on Satuday. The six readings, between 20:08 and 20:45, show the approaching darkness. On Friday, the sky brightness reached 21.55 mags/sq.arcsec.
