First Start Setup

  • Answer whether the app may use the internet for setup and user-started database updates.
  • Open the Privacy Statement link before answering if you want to review data handling. Set Up shows that local privacy review state later.
  • Completed Internet, Privacy, and Plan Save Folder actions dim after they are set; use Clear and Start Over to reset first-start setup.
  • The Finish card and Setup Checklist stay pinned. Collapse Details hides the explanatory setup text but keeps the checklist tick marks visible.
  • Choose preferred language, primary viewing location, and primary telescope with accessories.
  • After saving the primary telescope, the telescope editor collapses to the saved telescope/accessory summary and setup moves toward the plan folder step.
  • Choose or create a plan folder in Files, or save the folder setting to complete that setup item.
  • Use Finish Later only after the internet permission question has been answered.
First start and home setup path
First setup path and main home actions.

Home

  • Home opens Locations, Telescope, Targets, Planner, Weather, Set Up, and Help.
  • The telescope time entry accepts HHMM, 12-hour, and 24-hour values.
  • Applying the telescope time window saves the observing window used by weather and target planning, then routes you to location setup.
  • The compact top banner leaves room for the action buttons and bottom data card on iPhone.
  • The My Telescope card uses tighter padding so the lower information card stays readable.
  • The taller bottom data card shows Location Name, Telescope With Accessories, Total Targets, and Chosen Hemisphere Targets in larger dark yellow text on the standard blue background.

Locations

  • Save at least one valid observing location before target filtering or weather.
  • Use GPS when available. After GPS fills the site, Address Info collapses automatically and can be expanded again.
  • If you start a new location card, use Cancel to leave without saving it.
  • Manual address entry starts with Country so address labels match the selected country.
  • The page scrolls while editing so lower fields and saved locations remain reachable.
  • Only one saved location can be default at once.
  • Set Default promotes a saved location without re-entering site details, and Delete Location removes old sites.
  • Elevation is saved when available and is used for weather pressure adjustments.
Locations page
Saved observation locations and add-location controls.

Telescope

  • Select the smart telescope used for the observation plan.
  • Select compatible accessories before saving the telescope setup.
  • The planner report includes selected telescope and accessory names.
Telescope page
Smart telescope and accessory setup.

Targets

  • Use Update Data when target sources need refreshing.
  • Use the Current Setup card to expand or collapse the active target settings summary.
  • Catalog, Time, and Filter cards open popups. Apply catalog, time, and filter changes from inside those popups before reviewing the target list.
  • Action cards use glass status colors: green when a required setup block is valid, red until required user data is entered or the user has opened a filter without setting it.
  • The top Apply action has been removed so Catalog and Current Setup have more room.
  • Current target setup is held temporarily, so returning to Target Setup restores the active catalog, time, and filter choices.
  • If transient target data is stale, target cards show Update Data and remain disabled until refreshed.
Target filters
Target database filters and catalog scope.

Advanced Filters and Results

  • Use Advanced Filters for magnitude, altitude, magnetic azimuth, object type, and observing-window limits.
  • Altitude limits accept 0 through 99 degrees. Azimuth limits accept 000 through 360 degrees.
  • Obstruction ranges remove blocked azimuth or altitude areas from target candidates.
  • Clear Sky filter ranges can be added one after another without closing the card, and a new range can be canceled before saving.
  • Apply Filter validates required fields. If data is invalid, the app asks for the missing or corrected answer.
  • Use Add to Planner for unscheduled targets or Go to Planner for targets already in the plan.
Advanced target filters

Observation Time

  • Set start and stop time for each target.
  • After-midnight times are normalized into the same observing night.
  • The app checks for overlapping planned target windows before saving.
Observation time sheet
Target observation time sheet.

Planner

  • Review targets and adjust observation times.
  • Sort the plan by Start Time, Zenith, or Magnitude.
  • Save PDF, Preview, Print Plan, Delete Plan, Load Plan, and Share Plan are available when a plan is present.
  • After Load Plan, choose Yes to add more targets or No to stay on Planner.
  • The loaded plan name and loaded-plan message turn yellow.
Planner actions

Weather and Sky Info

  • Weather uses the default location and observing window.
  • If My Telescope times are set, the viewing period follows that initialize/stop window until a saved plan takes over.
  • The glass Date and Time Period Forecast card lists the active observing date and time range.
  • The Sun/Moon glass card shows Sunset, Sunrise, Bortle/SQM, and time of total darkness based on the saved location.
  • Bortle/SQM is estimated from the saved latitude, longitude, elevation, and nearby population light-pressure reference used by the app.
  • The compact Source row names the weather source and includes Update to reload the hourly data.
  • Hourly rows list time, icon, cloud percentage, rain chance, pressure trend, temperature, and dew point.
  • The Done action is kept above the menu bar on iPhone.
Weather and sky info
Weather source, sun/moon, Bortle/SQM, and local sky details.

Set Up

  • Set Up contains language, units, internet permission, update actions, and About This App.
  • Internet-required actions are labeled.
  • Target and smart telescope database updates are user-started.
  • Target Database Update summarizes changed transients, lists their names, and shows pulled-and-stored asteroid and comet names such as Ceres and Vesta.
  • Off-site pages open inside a controlled in-app browser with a return button.
Set Up page
Set Up and database update controls.

Help and Clock Support

  • Open Help from the question mark icon.
  • Help mirrors the major manual sections in shorter form.
  • Time entry accepts HHMM, 12-hour, and 24-hour formats, while displayed times follow the iPhone or iPad clock preference.
Clock support detail
12-hour and 24-hour clock support.

Troubleshooting

No targets appear

  • Save a default location.
  • Set required red Catalog, Time, or Filter cards, then use Apply Filters inside the popup.
  • Loosen magnitude, altitude, azimuth, object type, and obstruction settings.

Weather is blank

  • Save a valid default location with latitude and longitude.
  • Confirm internet permission for weather prediction data.
  • Add elevation when available.

Location will not save

  • Enter a location name.
  • Use GPS or enter latitude and longitude.
  • Choose Country first for manual address entry.

Plan load is confusing

  • Watch for the Plan Loaded prompt.
  • Choose Yes to add targets or No to remain on Planner.
  • Yellow plan text identifies a loaded plan.

Numeric keypad covers fields

  • Dismiss the keypad after entering the value.
  • Scroll cards under the filter card.
  • Collapse advanced filters after applying.

Asteroids or comets look stale

  • Run Target Database Update from Set Up.
  • Review the update summary for Small bodies updated, Pulled and stored, and Changed transients.
  • Stale transient target cards cannot be used until data is refreshed.

PDF or print does not appear

  • Confirm at least one target exists in the plan.
  • Use Preview first.
  • Use Share Plan if the device print sheet is unavailable.
All app data stays on the device. Internet access is used only for selected updates, weather, image lookup, privacy/support pages, and other user-started online actions.
