"Every amateur astronomer yearns for clear, dark skies, and this exhaustive app helps you find them." - Sky At Night Magazine 2017 "Several astronomy-oriented weather apps are available, but Scope Nights has become my favorite… it does a fine job of summarizing the data in a clear and understandable fashion." - Sky & Telescope Magazine 2015 "Conventional weather forecasts meet the needs of Earthly dwellers; news of cloud cover when sensible folk are asleep is hardly required. Now via this wonderful App… local forecasts for nocturnal weather… are now available." - Astronomy Now Magazine 2012 If you’re a stargazer, astronomer or astrophotographer, analysing conventional weather forecasts for favourable night time conditions can be very time consuming, you just want to know when to plan your stargazing trip or set up your telescope. Scope Nights analyses night time weather forecast data for you and shows exactly when and where to go for the darkest and clearest skies, as well as offering customisable stargazing ratings to suit your telescope and observing habits, stargazing notifications, and a detailed light pollution map showing nearby dark sky sites and observatories.

Choose night, evening or morning coverage to suit when you observe, the type of telescope, and the type of observing you plan to do. • View at a glance which of your favourite Scope Sites will have the most suitable conditions FIND DARK SKY SITES & OBSERVATORIES • Find nearby dark sky sites with the clearest skies using a detailed light pollution map derived from the latest NASA satellite data • Searchable lists and dark sky map showing certified dark sky places, major astronomical observatories and robotic telescopes DETAILED ASTRONOMY FORECASTS • Long range astronomy forecasts for any location worldwide, compare up to 10 locations up to 10 nights ahead • Local 3-hourly forecasts for UK & USA updated hourly using the best forecast data available direct from the UK Met Office and the US NOAA National Weather Service CUSTOM STARGAZING NOTIFICATIONS • Receive accurate notifications of good or fair stargazing ratings based on your custom thresholds, well before sunset so you can prepare for your observing session • App badge showing the number of sites with good observing conditions for tonight SHARE STARGAZING FORECASTS • Share astronomy weather reports with fellow astronomers via email, social media or print them out for your observatory DETAILED CUSTOM ASTRONOMY FORECASTS • Night time specific astronomy forecasts from sunset to sunrise • Forecast coverage to suit when you observe: All Night, Evening or Morning • Detailed colour coded forecasts: - Moon phase percentage & altitude - Cloud cover - Precipitation probability - Relative humidity - Minimum temperature in Celsius or Fahrenheit - Wind direction - Wind speed & gusts in Mph, Knots, Kph or Mps • Moonrise and moonset times • Sunrise & sunset times • Wind speed gust sensitivity switch for those with large telescopes or in exposed locations REQUIREMENTS • Requires a device with iOS 9.3 or later • Requires Internet access over a Wi-Fi or cellular data connection • Requires Location Services be enabled to automatically find local astronomy forecast • Requires Background Services be enabled to get stargazing notifications
The best way to know when to go out
Astronomical twilight start and end needs to be shown. Moon rise/set time should be shown more prominently Font size should be a little bigger
I run the sky watches at the Horowitz - DeRemer Planetarium . It is very helpful and accurate to know when it will be clear . This app is always right on . The dark sky map is also helpful when planning an observing trip .
App does a great job of forecasting conditions for astronomy. Its my go to app. Far better than using even the best standard weather apps.
I find this app to be useful for a first look at the possibility for decent skies. Your mileage may vary. If you’re a stargazer like me, you know that the weather does whatever it feels like to us poor mortals. But definitely a good thing to have in your toolkit.
One of my go to Astro viewing weather apps. Its long range forecasts are more correct than not. The graphic display is easy to read and pleasant to look at.
Great app. One of my go To Astro tools.
The app is good, and there is no alternative in the market. However, the app is full of various bugs which makes it unusable. The search function is very primitive. The favorite site list keeps dropping earlier saved spots. The list keeps going.
Generally accurate & easy to use. Didn't like having to purchase features 1st version included (at much lower price)....but still a very useful app.
I rely on this program to plan my scope nights. It’s rarely been off much
