I used a dedicated (cooled) astrophotography camera attached to a prime 135mm/F2 lens (wide field). I took 120 frames with 60 seconds of exposure time each. The frames were stacked into a single one and processed using several astrophotography programs with a final touch-up with Affinity Photo.
Here is a picture of the hardware used:
The big red cylinder to the left is the main cooled camera attached to the lens. The small scope on the top (also with a small camera) is a guide scope used to accurately track a set of stars in order to keep the target centered on the frame. All is mounted on a tracking motorized mount (attached to the tripod) which is controlled by the guide scope. That is necessary to counteract the Earth’s rotation.
The small red box is a glorified Raspberry Pi with the software that controls everything through an UI on a tablet or cell phone using wi-fi (little antenna on top of the guide scope).
Yesterday we jumped the train from our home in Cheshire, up to the Calder Valley in West Yorkshire. Journey is just over an hour and at £15 return ticket, a bargain. We walked the Rochdale canal from Todmorden to Hebden Bridge. A very pleasant walk, albeit a little bit warm at 26c. Honestly not complaining
