NINA Field Kit

Combine required Alpaca safety sources into one result for N.I.N.A., with background checks, retries, and limits on stale readings. An absolute-HFR autofocus trigger checks focus before the next light exposure.

Regain

Regain control of your equipment: retryable, fault-tolerant camera capture that re-reads a frame still held in camera memory instead of throwing away a long exposure, with the vendor SDK in a separate Rust worker so a hung camera does not take the session down. One set of drivers, not tied to a single vendor, for cameras, rotators, filter wheels, focusers and flat panels, with the same setup across N.I.N.A., Windows ASCOM and an Alpaca server that runs on Windows, Linux and macOS.

Chatstronomy

Image previews, autofocus curves, guiding graphs, and session updates in Discord or Matrix. Pair the N.I.N.A. plugin with the hosted Hub, or use your own local chat integration. Optional Discord commands use permissions set at the observatory.

AutoPierCam

Keep a view of the rig with background still capture from a ZWO ASI camera. The Windows tray app adapts exposure between day and night, manages uploads, and supplies a read-only pier-camera panel in N.I.N.A.

PSF Guard

Grade and organize FITS/XISF captures, match calibration libraries, and build resumable mono and color stacks. Use a standalone catalog or connect to N.I.N.A. Target Scheduler so grading decisions reach the sequencer.

Seiza desktop apps

Browse FITS and XISF folders, stretch previews, solve locally, and stack a capture folder as frames arrive. Star measurements and sensor-region diagrams help investigate changes in image quality across the field.

Plate solving in the browser

Upload an image to seiza.fyi for a plate solution and object overlay without installing an application. The open-source seiza-server supplies the web interface, queued solving, and downloadable WCS.

FITS & XISF for Photoshop

Native Seiza format plugins add FITS and XISF to Photoshop's Open and Save dialogs on Windows x64 and Intel or Apple silicon Macs. Import as Float32 or rescaled 16-bit, optionally debayer tagged mosaics, and save at the document's depth.

Same-format saves retain source metadata, which can also travel through PSD/PSB in XMP. Format output is one flattened image; keep originals and re-solve after geometric edits. These early releases have automated host tests, with interactive Photoshop validation still pending.

Foraxx Palette Utility for PixInsight

Build a Foraxx palette, or a plain SHO, HOO, HSO or OHS mapping, from stretched, starless narrowband images, with an optional stars image. Shape the two mixing masks, lift faint channels, generate ratio masks, and boost colour through a protected mask. Installs from the theatr.us PixInsight repository and updates through PixInsight. Based on Paul Hancock's original script; palette by The Coldest Nights.

Foraxx Palette for Photoshop

The same palette as ordinary, mergeable Photoshop layers: the non-linear Foraxx factors become two layer masks, and the channels are screened together, so you keep editing after the build. A UXP plugin for Photoshop 24.4 and newer, with a preview.

Foraxx in Seiza

Seiza's stacking colour pipeline can render the Foraxx palette directly from calibrated narrowband masters, for a first look before any manual processing.

Seiza engine

A Rust engine for hinted and blind plate solving, calibration, batch and live stacking, and star measurements. The CLI, Python bindings, and native C API offer several ways to integrate it.

Seiza overlays

WCS coordinate grids, catalog labels, and satellite-track overlays for web applications, with a React SVG renderer and PNG export.

Tenrankai

The gallery and blog engine behind this site. A flat-file publishing workflow meets an image pipeline with HDR AVIF, color-managed resizing, watermarking, and Seiza-powered astronomical overlays.
