Astrophotography: capturing data & processing images

Описание: This is a video derived from the slides I used for a talk to the South East Kent Astronomical Society (https://sekas.co.uk/) which I was asked to prepare for their July 2025 monthly meeting. I had promised them a follow-up blog post - this is offered in lieu.

It was recorded in a single take using the 'record' facility in MS PowerPoint, without a script or notes in order to try to get as close as I could to the 'live' experience. (Nothing can truly match sharing my love of science face-to-face with a group of people who can provide real-time feedback.) Also, it would simply be too dispiriting to deliver a long and stilted scripted monologue. The upshot is that viewers will get all my stumbles, throat-clearing, failures in memory and moments of lost track: forbearance is a good quality in such contexts ;-)

I apologise for the lack of subtitles. I tried using the YouTube algorithm to generate them but it made so many horrendous mistakes that the result was, in essence, unintelligible. I was left with a choice between editing almost ½ the words or switching them off; I chose the less onerous path.
