- Refresh the specs snapshot with:
  `curl -sL "https://docs.google.com/spreadsheets/d/1jZWkkjewOuyNC9YzQ8y2d0pO1e4T7EBeysmQMPBVSOk/export?format=csv" -o data/itelescope-telescopes.csv`
- The CSV has multi-line cells (quoted); line count is not row count. Telescope rows
  start `T<number>,`; observatory header rows have an empty first column.
- Sensors are 16-bit ADC unless noted (T20's ASI2400C is 14-bit).
- Free scopes (30 min/day): T68 (Utah), T33 (Siding Spring).
- Minimum elevation limits come from the support article, not the sheet.

## Automation recon (2026-07-18, all verified live)

Credentials live OUTSIDE this repo (local claudetemp, never commit them).

- go.itelescope.net is ASP.NET WebForms. Login: GET /login.aspx, POST
  UsernameTextBox/PasswordTextBox plus __VIEWSTATE, __VIEWSTATEGENERATOR,
  __EVENTVALIDATION, LoginButton=Login; session cookie then works everywhere.
- JSON service at /DataService.svc (session-cookie auth): GetAccountStatus
  (balance, plan, renewal), GetMyAvailablePlans (per-plan, per-scope
  AccessDiscount), ApplyPromoCode (POST). More methods likely; enumerate from
  inline $.ajax calls on each page (Scripts/Common.js has none).
- Home page /default.aspx carries live network status text (per-scope
  offline/online reasons) plus points balance: cheap to poll.
- Reservation/Overview.aspx links every telescope's own control server:
  https://tNN.itelescope.online/ or http://tNN.itelescope.net:80NN/. These are
  ACP web servers behind HTTP auth accepting the same iTelescope credentials
  (verified read-only on T33: index.asp is a TiddlyWiki info page, min elevation
  20 degrees, 900 s max exposure). Session control and plan submission happen
  here; ACP endpoint mapping is the next step.
- Reservation/Planner.aspx now redirects to https://lookup.itelescope.online
  (new planning tool, not yet explored).
- Weather per site: Weather/Weather.aspx?site=UDRO|SSO|DSC|SRO|AC|EYE.
- Account: Plan-40 (GBP 32.00 per 28 days), renewal 12 Aug 2026, subscribed
  since Apr 2019, balance 2,638 points at recon time.
