Fabulous app! Thank you!
My go-to app for identifying objects in the night sky. Always up to date info (as far as I know) I have recorded many objects that do not seem to be listed ...?
This is a really useful app. I wish, however, instead of just having a filter to turn on and off all starlink satellites, it had a filter to turn on and off all starlink satellites less than a week old. After about a week or so they become much fainter and harder see. the older starlinks aren't of interest to most observers.
Comet details would be good, they arent regular, many years, thousands sometimes before returning COMETS
Great app, nice looking interface, very useful information. However, in my phone, the notification for satellite passes dont work. Waiting for a web version.
Like it...
Awesome app, great for Ham radio satellites, ISS fly by, planet's and so much or. Very easy to use.
Radio frequencies get shifted according to doppler effect during pass.
Dialog discloses use of location data.
