See your astrophotography
projects at a glance.

A desktop app that reads your existing FITS, XISF, and DSLR raw files in place — calculates integration time, finds matching calibration frames, and analyzes sub-frames without ever moving or copying your data.

What it does

Designed for the messy reality of capture sessions.

You come home, copy cards, stash frames in a dated folder — and then, a week later, try to remember which calibration matches what. This is the tool that remembers for you.

Reads your files in place

Point it at your capture folder and it indexes what's there — your files stay where you put them. The scan is cached in a small .json next to your library; delete it any time and the next scan rebuilds it.

Integration time, automatically

Each project, filter, and session gets its total exposure calculated from FITS headers. No spreadsheets. No arithmetic. Just the number, updated as you add frames.

Matches calibration frames

Tells you which projects have darks, bias, and flats ready — matching by exposure (±0.5 s), sensor temperature, and resolution. You see at a glance what's missing.

Sub-frame star analysis

Per-frame FWHM, eccentricity, star count, and HFR. Built-in heatmap and tilt visualization help you spot collimation drift or a bad night before you stack.

Fast preview browser

JPEG previews generated on demand with a bounded in-memory cache. A priority queue means clicking a new filter jumps straight to those frames — previous work keeps cooking in the background.

Guided import, no drag-drop

Pick the frames you want (e.g. straight from ASIAIR) and the app copies them into the right Project/Filter/Session subfolder for you — no hunting through Finder or Explorer, no manual moves, no misfiled nights.

Your files, untouched

A structure that keeps itself tidy.

Some catalog apps suck your data into a proprietary database. When the app goes away, so does the structure — sometimes the files themselves.

This one doesn't. It expects a simple, predictable folder layout — Project / Filter / Session / Lights · Flats — and reads FITS and XISF headers directly off disk to build its view on top. The convention is the contract: follow it and the app does the rest; ignore it and nothing is hidden from you — the files are still just files.

Nothing is encrypted, re-encoded, or moved behind your back. Delete the app and your 2 TB of lights stay exactly where you left them, ready for PixInsight, Siril, APP, or anything else.

Inspection

Open a frame, see what matters.

Headers, star metrics, and a preview — without launching anything else.

Every frame you've captured, on the sky.

All your project FOVs plotted on a deep-sky survey background. Useful for choosing the next target, remembering what you already framed, or spotting gaps in a mosaic.

Will it be clear tonight?

Seven-day hourly forecast focused on what matters for imaging: low/mid/high cloud layers, humidity, dew point, wind, visibility, and precipitation probability — with moon illumination and sun/moon position bars. Click a day to expand the full hourly breakdown.

Compatibility

Works with the tools you already have.

If your capture software writes standard FITS headers, this reads them.

Give it a night.

It's free, it's open source, and it won't touch your files.
If it helps, great. If not, it's a single uninstall away.
