The first usable alpha of Argos — desktop capture and differential photometry for the ZWO Seestar S30 Pro. From raw frames to a light curve, on your laptop, as the light lands.

What it does

  • Capture & control — GoTo, tracking, live view and multi-step sequences over ASCOM Alpaca, with the native Seestar link for the moves the firmware won't expose.
  • Science-grade FITS — every sub written with the headers the Seestar leaves out (exposure mid-times, gain, airmass, Moon separation), ready for Siril / PixInsight / AstroImageJ.
  • Astrometry — ASTAP plate-solves every frame; each pixel maps to real sky coordinates, even on short live subs.
  • Photometry — aperture photometry + AAVSO-ensemble differential magnitudes, a live light curve, and CSV / AAVSO export.

From quick-look to publishable

Argos stops at honest subs + a live quick-look. For the calibrated, phase-folded, AAVSO-ready curve, its frames drop straight into Siril with star_var_script — validated on RR Lyr against the published Sesar 2010 template.

Run it

Dev flow for now (packaged builds to follow):

brew install uv
git clone https://github.com/jperret21/argos.git
cd argos
uv sync --extra dev
uv run python main.py

No telescope needed — it runs against the ASCOM Alpaca simulator (see docs/simulator_testing.md).

Alpha caveats

  • Autofocus routine not yet wired (focuser control is).
  • Calibration (darks / flats) is intentionally left to post-processing in Siril.
  • Field-tested on the S30 Pro — expect rough edges, and please open issues.
