PSF Guard no longer needs a N.I.N.A. Target Scheduler database — point it at folders of FITS files and it builds the catalog itself. Also new: a calibration frame library, catalog-to-catalog sync (even between two running servers), scheduler planning, and signed desktop updates.
Read more →A new project: TopoSaic is a local-first desktop app that turns any place on Earth into a 3D-printable terrain jigsaw — real elevation data, land-cover colors, roads, rivers, and buildings, cut into watertight puzzle pieces with proper round tabs. Rust engine, live 3D preview, STL and color 3MF out.
Read more →Seiza grows from a plate solver into an imaging engine: linear calibration and live stacking, satellite track identification, background extraction and deconvolution, XISF support — plus native Mac and Windows apps on a shared C ABI. And in PSF Guard, the promised integration landed: plate-solve grading, satellite ID, and full color stack previews.
Read more →Six releases in six days: seiza becomes Siril's plate solver via a solve-field drop-in, gains Python bindings and SIP distortion, a guided Windows installer, rank-robust matching, and a shared overlay renderer on npm — with seiza-server 0.2 riding along and a PSF Guard integration up next.
Read more →Seiza gets a hosted demo: upload any sky image at seiza.fyi and get a durable solution page with interactive catalog overlays — deep-sky objects, field stars, live transients, an RA/Dec grid, and a rendered PNG export. Under the hood: a durable job queue and an astrometry.net-compatible API.
Read more →星座 — a new Rust plate-solving library: star detection, WCS fitting, and blind solving of a 24 MP field in under two seconds including building the whole-sky index. Now wired into tenrankai, where astro images get object overlays and live supernova markers.
Read more →The July 2026 era: a full posts revamp with categories and a permission-gated editor, RSS feeds, gallery-aware posts with hero click-through, embeddable post previews — and a sky map on image detail pages, drawn from the same RA/Dec metadata astrophotographers already write.
Read more →Catching a two-day-old supernova at sunset: a quick 8-minute run on the EdgeHD 9.25 captured SN 2026sqf, a fresh Type II supernova in the starburst galaxy NGC 3310.
Read more →Status check on the Calcumaker 16 — a Cherry MX programmer's RPN calculator in the HP-16C tradition with arbitrary-precision math. The full software stack is done and running (try it in your browser); the three-board hardware design is in active development.
Read more →The new release of PSF Guard learns to see what global statistics miss — partial occlusions, thin cloud veils, small clouds, and errant light — using grid metrics and classical differential photometry, with annotated images explaining every verdict.
Read more →M51 and its companion NGC 5195 framed as a cosmic question mark — a close galactic encounter 30 million light-years away, from the EdgeHD 9.25.
Read more →The unglamorous spring: frontend test frameworks, OOM-proofing the batch pipeline, cache-validation headers, security audit passes, a stateless URL shortener, DynamoDB config storage, automatic sitemaps, and per-folder sort control.
Read more →One month, ninety commits: a React image-detail SPA with tile-based deep zoom, comments anchored to image regions, AI alt-text, S3 and pluggable user storage, multi-site virtual hosting, RAW file versions, HEIC/HDR support, and an admin UI.
Read more →The decade-later successor: an 8-channel TPS922053 driver board with an onboard ESP32-S3 running all 17 PWM channels, an embedded astronomical scheduler with a React frontend, Carvera-machined heatsinks, and copper-core PCBs from JLCPCB.
Read more →IC 1396 in Cepheus, a vast emission complex about 2,400 light-years away, with the famous Elephant's Trunk — a dense globule of gas and dust being eroded and lit from behind by the hot O-star at the cluster's heart — winding through the middle.
Read more →The birth of Tenrankai (展覧会 — 'exhibition'): a flat-file Rust gallery server that went from 'Init' to masonry layouts, EXIF extraction, a blog engine, passwordless auth with passkeys, and full AVIF HDR gain-map support in its first ten days.
Read more →M33, the Triangulum Galaxy in HaLRGB — 2.7 million light-years away, with hydrogen-alpha lighting up its star factories, from four hours of 15-second subs plus 3nm Hα.
Read more →Sh2-92, nicknamed "The Scream" for the anguished face that emerges in narrowband renders — a faint, rarely imaged H II region in Vulpecula.
