What a small telescope in Lisbon can measure, and where in the sky each picture was taken.

Each photograph at the place on the sky where it was taken; a small dot is a frame without a report, further down the page. Saturn and Jupiter where they stood in mid-October 2023; the nights of their photographs are not recorded.
What this is
These are observations made from Lisbon, most of them with a Seestar S50, and the analysis that follows each one.
Every entry reports what was captured, what the measurements support and what they do not. A prediction from a catalogue is never counted as a detection, and none of the entries claims a discovery.

22 Aug 2026Seestar S50 · Lisbon
Fifty-two minutes on M33: a documented rendition, faint structure repeating across independent stacks, 649 isolated catalogue associations, bounded nulls on short-timescale change.

The 12 August 2026 partial eclipse from Lisbon: 1,512 raw observations matched to JPL DE440s geometry, and all 3,011 camera timelapse frames rigidly aligned, failures left visible.

Ulula, Juno, Melpomene and Vienna recovered where predicted over four nights; a strong point source consistent with comet 169P/NEAT; C/2024 J3 a weak hint that failed confirmation.

An edited Andromeda photograph, audited: the FITS is the JPEG exactly; the sky solution holds at field scale; 76 of 77 Gaia positions match; the old stellar census is withdrawn.

Asteroid (714) Ulula measured in three independently solved 30-second exposures of the Pleiades field, then placed on its orbit and, at 41 km, set at the scale of Portugal.

Method
Every raw frame is sealed by hash before analysis begins, and only runs that passed a science review are published.
The films and the phone-format slides under each report come from the same runs.
Instrument
Every 2026 observation, from Lisbon, and from Praia de Algés and Praia de Carcavelos for the eclipse.
Instrument
Planets and the Moon, 2023, with the phone held to the eyepiece.
I take 20-minute calls on weekdays, 09:30 to 18:00 in Lisbon. Pick a day and an hour.
