Everything it does,
and why.

Akastroid makes hundreds of decisions automatically. Here is what they are.

Getting your data in

Whatever your camera writes, Akastroid opens — no converting, no exporting first.

FITS

The astronomy standard. Seestar, ZWO, ASIAIR, N.I.N.A., anything.

Camera RAW

Canon CR2 and CR3, Nikon NEF, Sony ARW, Fujifilm RAF, Olympus ORF, Panasonic RW2, Pentax PEF, Adobe DNG and more.

Planetary video

SER in every common colour format, and AVI both uncompressed and MJPEG.

Calibration

Darks, flats and bias found from your folder layout and applied without being asked.

Deciding what is worth keeping

Every frame is measured before anything is stacked, and every rejection comes with a reason.

Star quality

Count, sharpness, roundness and how far each frame's stars have drifted from the session's own norm.

Sky quality

Background level, gradient strength, noise and signal-to-noise.

Artefacts

Cloud, satellite and aircraft trails, lost focus, overexposure — each named.

Your call

Overrule any automatic decision with a click. Nothing is hidden.

Building the image

The expensive, once-per-session work: alignment and integration.

Star alignment

Asterism matching, so frames that rotated between exposures still line up. An alt-az mount is no problem.

Integration

Averaging, median, sigma clipping or winsorized clipping — chosen from how deep your stack is, not from a preference.

Drizzle

Reconstruct at higher resolution when your frames were dithered. Akastroid measures whether they were and says so.

Mosaics

Panels matched into an overlap graph, level-matched at the seams and feathered together.

Making it look right

Adapted to what is actually in your frame, not to a preset.

Gradient removal

Light pollution, moon glow and vignetting modelled and removed while the sky keeps its level. A background subtracted to black looks wrong.

Photometric colour

Your field matched against 533,000 catalogued stars with measured colours, and the white balance fitted to what those stars actually are.

Adaptive stretch

The curve is solved from your histogram, not guessed, with bright cores protected so a nebula core stays a core.

Denoise and detail

Multiscale, applied hardest where the signal is weakest and held back over real structure.

Planets and the Moon

Lucky imaging, in one application rather than four.

Frame grading

Every frame in the capture scored for sharpness, with a graph of how the seeing changed.

Multi-point alignment

The disc tracked in pieces, so the atmosphere's local warping comes out. This is what separates a soft stack from a sharp one.

Finer-grid integration

An undersampled planet is integrated onto a finer grid, recovering detail below the original pixel scale.

Dispersion and wavelets

Red and blue realigned to green, then six sharpening layers you control directly.

Finishing and sharing

Three styles

Natural, Enhanced and Dramatic, all rendered from the same data. Switching is instant.

Colour tools

Histogram, curves, hue-selective saturation, green-cast removal, temperature and tint — with a live preview.

Export

JPEG and PNG for sharing, 16-bit TIFF for printing, and a FITS master that keeps the float data and a record of what was done to it.

Gift artwork

A print-ready poster built around your real telescope image, with the photograph and the decoration clearly labelled as different things.

What Akastroid will not do

It runs no generative model. Nothing paints in nebula structure, invents detail or sharpens by hallucination. Machine learning is used to measure and tochoose — frame quality, noise, artefacts, parameters — never to add something the telescope did not record. Every pixel in your finished image traces back to a photon, and the processing log tells you what happened to it.
