- 07Jun202605 / EquipmentA small telescope on a cold island: dew, frost and low targetsCooling times, dew shields, frost on a mirror, and the large part of the southern sky that a six-inch reflector at this latitude can never reach.
- 30Nov202504 / PlanningPlanning a clear night around the moon, the forecast and the boatHow I plan a month of observing around the lunar cycle, an unreliable coastal forecast, a winter boat timetable and the cold on an open jetty.
- 09Mar202503 / AuroraAurora at fifty-nine north: what is honest to expect down hereAurora seen from fifty-nine degrees north is rarer and lower than the photographs suggest. What the indices mean here, and two nights that delivered.
- 13Oct202402 / BinocularsA pair of 10x50s from the jetty: what binoculars really reachFour autumns of notes on what a hand-held pair of binoculars actually reaches under a bright northern sky, and what they will never show.
- 26May202401 / SummerFour months without a proper night: summer at fifty-nine northWhy there is no astronomical darkness here between late April and late August, what is still worth observing, and how to use the season.
A clouded-out night still gets a line in the paper notebook, but it does not become an entry here unless something was actually seen or something was actually learned about the site.
