AllSky: new box, dark frames & other tweaks

When conditions allow, I've been having fun with Allsky.

What started because of a meteor shower, has become a wider interest in things in the night sky.

And I've been tidying & tweaking my system.

Re-discover the Night Sky: star trails

With an improvement in the weather, I thought I'd try a bit of night-sky photography.

One thing I've never attempted is taking time-lapse photos and then stacking them to produce star trails.

I used a RaspiCam for the photos and Gimp to stack and process them.
