Run your telescope and process the sky, from your browser
astronomy.today connects an interactive planetarium, remote control of your Seestar and DWARF smart telescopes or your ASCOM Alpaca equipment through a home agent, automated observing sequences, and a full astrophotography editor. The planetarium and editor run in your browser; controlling your telescopes needs only a small home agent you download once.
Everything for a night under the stars
Observatory control
Drive your mount, camera, focuser, filter wheel and dew heater from any browser — Seestar and DWARF telescopes, ASCOM Alpaca devices, over a home agent that needs no inbound ports.
Observing sequences
Build a plan of gotos, stacks, focus and filter steps. It runs on the home agent, so it keeps going when you close the tab and resumes after a restart.
In-browser image processing
Browse your telescope's captures, view and download FITS, or load your own FITS/PNG and edit it: gradient removal, histogram stretch with a star mask, noise reduction, sharpening, colour and rotate/crop. No AI is used — every step is a classic, transparent algorithm.
Interactive planetarium
A fast, zoomable sky map with stars and deep-sky objects. Find a target, check tonight's visibility against your horizon, and send it straight to the telescope.
Multi-rig dashboard
Watch and control several telescopes and their running plans at once from a single board — status, progress, pause, resume and stop.
News, blog and gallery
Astronomy news, field notes on real sessions, and a gallery of captures with the full acquisition details behind each one.
Your telescope stays on your network
1 · Pair a home agent
A tiny program runs on a machine on the telescope's network. It connects out to astronomy.today over HTTPS, so there are no ports to open and nothing exposed to the internet.
2 · Control from anywhere
Slew, focus, change filters, run stacks and follow live status from any browser. Direct-IP telescopes on your LAN work straight from the web too.
3 · Capture and process
Sequences run on the agent and survive a closed tab. Browse the captures and finish them in the browser editor, or load your own FITS and PNG.

Frequently asked questions
What is astronomy.today?
astronomy.today is a web platform for amateur astronomers and astrophotographers: an interactive planetarium, remote control of your Seestar and DWARF smart telescopes or your ASCOM Alpaca equipment through a home agent, automated observing sequences, and an in-browser image processor for FITS and PNG.
Do I need to install anything?
To explore the planetarium, browse content and use the image editor, no — it all runs in your browser. To control equipment on your home network you download a small home agent and run it on a machine there; it connects outward over HTTPS, so no ports need opening on your router.
Which telescopes and devices are supported?
Seestar (S30/S50 and S30 Pro / S50 Pro) and DWARFLAB (DWARF Mini, DWARF 3 and DWARF II) smart telescopes, plus ASCOM Alpaca devices — mount, camera, focuser, filter wheel and switches — each driven over its own native protocol through the home agent.
Can I process my astrophotography here?
Yes. Browse the captures your telescope saved, view and download FITS, or load your own FITS/PNG and edit it in the browser: gradient/background removal, histogram stretch with an optional star mask, noise reduction, sharpening, brightness/contrast/saturation and rotate/crop.
Does an observing plan keep running if I close the browser?
Yes. Sequences run on the home agent, not in the browser, so they keep going when the tab is closed and resume where they left off after a restart.
