This image was created from 75 stacked shots taken at Chillingham in Northumberland last Spring. The light in the bottom corner is Alnwick. I was using a Pentax K50 with a Samsung 16mm f2 lens, the whole lot being mounted on my home built barn door tracker. The tracker is powered by a stepper motor controlled by a Raspberry Pi. In use, a 5v power bank is gaffer-taped to one of the tripod legs and an electric lens warmer is used to prevent dew formation. The power bank can keep things running for about 4-hours, the camera having its own in-built intervalometer. Start it up, go to bed.
Although the post-processing may need some work, I reckon I may have got away with it!
