WORK IN PROGRESS

GnoNightSky: Decentralized Telescope Network

Connect telescopes to the Gno.land blockchain. Telescope owners share access to their equipment; anyone with access can point the telescope at any target and get a captured image back.

Goal: Observe anything in the sky in real time through a community-driven telescope network.

Components

Path	Type	Role
gno.land/p/vik000/nightsky	package	Shared types, TelescopeRealm logic, render functions
gno.land/r/vik000/nightsky	realm	Telescope registry, global capture feed
gno.land/r/vik000/telescope	realm	Vik's personnal telescope - usable as a template
telescope-controller/	Go binary	Hardware bridge to telescope

Deploying Your Own Telescope

1. Deploy your telescope realm

Copy gno.land/r/vik000/telescope and update:

• owner address in init()
• telescope name, model, coordinates
• package path in gnomod.toml

Registration with the network happens automatically from init() via registry.Register(cross, config).

Then publish your realm:

gnokey maketx addpkg \
  -pkgpath "gno.land/r/yourusername/telescope" \
  -pkgdir "." \
  -gas-fee AMOUNT -gas-wanted AMOUNT \
  -broadcast -chainid CHAIN -remote rpc.gno.land:443 \
  YOUR_ADDRESS

3. Configure and run the telescope controller

Edit telescope-controller/config.ini.

Build and run:

cd telescope-controller
go build -o telescope-controller .
./telescope-controller

The controller polls :status every interval_seconds, reads :commandData when a command is queued, executes the configured binary (blocking), uploads the result to Imgur, and reports back via RecordCapture.

Capture args are appended as positional parameters:

telescope_control.py capture <ra> <dec> <exposure_seconds>
telescope_control.py stop

Submitting Commands

Via the web UI

Navigate to gno.land/r/yourusername/telescope:control - an interactive form lets you choose capture/stop, enter RA/Dec/exposure, and submit directly through your adena wallet.

Via gnokey

# Capture - RA in hours (0–24), Dec in degrees (−90–90), exposure in seconds (1–300)
gnokey maketx call \
  -pkgpath "gno.land/r/yourusername/telescope" \
  -func "SubmitCommand" \
  -args "capture" -args "5.5" -args "22.5" -args "60" \
  -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid portal-loop -remote rpc.gno.land:443 \
  YOUR_ADDRESS

# Stop
gnokey maketx call \
  -pkgpath "gno.land/r/yourusername/telescope" \
  -func "SubmitCommand" \
  -args "stop" -args "" -args "" -args "" \
  -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid portal-loop -remote rpc.gno.land:443 \
  YOUR_ADDRESS

Granting access

gnokey maketx call \
  -pkgpath "gno.land/r/yourusername/telescope" \
  -func "GrantAccess" \
  -args "g1friend_address" -args "30" \
  -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid portal-loop -remote rpc.gno.land:443 \
  YOUR_ADDRESS

durationDays = 0 means access never expires.

Current hardware

• Seestar S30 / S50 smart telescopes (~$500–700)
• Controlled via seestar_alp or a custom telescope_control.py

---

Roadmap

• Phase 1: Working prototype - one telescope, command queue, Imgur captures, web forms, access control
• Phase 2: Multi-telescope network with map, bidding/scheduling for telescope time
• Phase 3: Integration with professional 3-axis mounts and higher-end cameras
• Future: DIY telescope builds using 3D printing and open-source designs
