Setup for the Geminids

With the Geminids peaking tonight and a clear sky after two nights of snow, I charged the camera battery and got a quick setup going to take some pictures of the sky.  As for any nigh sky photo, both lens stabilizer and auto-focus is set to OFF and focused manually at infinity. Then found a corner of the yard shielded from stray lights and planted the tripod, roughly aiming the camera 70deg up and pointing east (the constellation Gemini was rising at 10pm).

However at -15C outside, the old battery wouldn’t last very long.  I left it running for about 30 minutes, taking 20 seconds exposure at ISO 800 with a 17mm F4 lens.  The camera is now thawing (covered with frost after bringing it indoors) and will wait until tomorrow before checking the pictures out.

Setup for the 2017 Geminids

In the brief moments that I was outside I caught a 2-3 meteors and one really bright one (easily visual magnitude -4). So even living in the city, the Geminids are visible and accessible to all.  With my feet deep in snow I wasn’t dressed well enough to hang around in the cold wind to watch the show for long. So I hope the camera managed to capture a few.
