Complete the catalog.
A photo library for your smart telescope. A desktop app that turns a growing pile of Seestar or DwarfLab captures into an organized deep-sky library — catalog, capture tracking, ingest, Siril processing-prep, session planning, a sky map of everything you've shot, and safe backups, with a north-star goal to chase.
🔒 It never touches your originals. Ingest is always preview-then-confirm and copies from your telescope — your capture files stay exactly where they are.
Every object you've shot, organized by catalog (Messier, Caldwell, and more) with status, integration time, and a per-object journal.
Plot your whole collection on a star chart. Filter to a goal and the rest of that list joins the chart in grey — so you can see your progress, and the gaps.
Point it at your Seestar, DwarfLab scope, or a folder; it groups, names, and files your subs, stacks, and finished renders — you preview before anything is written.
Sessions, frames, filters, and integration roll up automatically from your FITS headers, so you always know what's done and what needs another night.
Automatically arranges a clean, contained Siril sandbox per target — lights linked, a tuned preset ready — then imports your finished work back.
Track your progress through a curated catalog (Messier, Caldwell, and more) or your own custom goals — always knowing what's still missing. Named for the 110th and final Messier object.
See what's up tonight, ranked by what your goals need — with a moon-aware schedule, an altitude timeline, and a printable field guide for the session.
Connect your own AI assistant and ask it things like "what should I shoot tonight?" or "critique my M51" — answered from your site, horizon, and capture history. It can suggest; it can't change your library.
Local-first, open source, and careful with your data — with built-in, hardlinked backups so an irreplaceable library stays that way.
