Astro Lab
Go beyond basic field-of-view calculations. Model your optical train, plan camera exposures, judge planetary seeing and understand what a telescope-and-eyepiece combination will really show.
Optics & imaging tools
The Lab is designed for practical equipment decisions and observing-session planning.
Planetary Image Processor
Upload an AVI or SER capture and let Siril MPP test multiple lucky-imaging stack depths, choose the strongest result and apply restrained planetary enhancement automatically.
Process a planetary capture Members-only beta 02Deep-Sky Image Processor
Upload one FITS target with its calibration frames, then calibrate, register, grade and stack it before tuning the final histogram stretch interactively.
Process deep-sky data Available 03Barlow & Focal Reducer
See exactly how a Barlow or reducer changes focal length, focal ratio, visual power, exit pupil, camera sampling and field of view.
Open optical train simulator Available 04Sub-exposure Optimizer
Use camera read-noise data, gain, focal ratio, filter and sky quality to find a sensible sky-limited sub-exposure range.
Open exposure optimizer Available 05Planetary Seeing Forecast
Separate cloud transparency from atmospheric steadiness with NOAA GFS jet-stream, wind-shear and thermal-stability guidance for planetary observing.
Open seeing forecast Available 06Eyepiece View Simulator
See the Moon and planets through a physically scaled circular eyepiece field, with live magnification, AFOV, exit pupil and empty-magnification guidance.
Open eyepiece simulator Available 07Deep-Sky Exposure Planner
Choose a popular target, camera, gain, focal ratio, filter and sky quality to plan both efficient sub-exposures and useful total integration.
Open deep-sky plannerThese tools model optical and imaging trade-offs in more detail than the general Astronomy Tools. They complement, rather than replace, the existing calculators and observing planners.
