I recently set up SyQon DeepPrism AI and Parallax (Deblur & Star Corrector) in PixInsight and hit a few snags, so here’s the full process.

How it works: each SyQon product has two parts - a CLI engine (the zip you download from your syqon.eu dashboard) and a PixInsight script that drives it. The dashboard zip alone won’t show up in PixInsight; you need both.

Step 1 - CLI engines. Download your purchased builds from the SyQon Download Center, extract each zip to a permanent location (e.g. a folder on your data drive). Keep each *_cli.exe together with its _internal folder - they don’t work apart.

Step 2 - PixInsight scripts. Add this repository in Resources > Updates > Manage Repositories > Add:

https://raw.githubusercontent.com/SyQon-Hub/PixInsight_Scripts/refs/heads/main/

Then Resources > Updates > Check for Updates > Apply, and restart PixInsight.

Step 3 - the gotcha. On PixInsight 1.9.4 (build 1975) the updater says “There are no updates currently available” - the SyQon repo currently declares compatibility only up to 1.9.3, so PI silently rejects it. Manual workaround: download the latest SyQonScripts zip from https://github.com/SyQon-Hub/PixInsight_Scripts and extract it anywhere permanent. Then in PixInsight: Script > Feature Scripts > Add > select the extracted src/scripts folder > OK > Done. Prism, Parallax, and Starless now appear under Script > SyQon.

Step 4 - connect the engines. Open each script, and in the Executable section at the bottom point it to the matching CLI exe from step 1 (Prism > prism_cli.exe, Parallax > parallax_cli.exe). The path is remembered. Licensing is account-based - it verifies against your SyQon login on first run, no key to paste.

Notes: first Prism run can be slow while the ~400 MB ONNX model loads. If you later move the CLI folders, re-point the scripts. Since the manual install bypasses the update system, grab new script versions from the GitHub repo when SyQon releases them.

Clear skies!
