Makes astronomy accessible

Love my evscope. It makes astronomy accessible as as a hobby for anyone. The app is fantastic. Three problems it has is: (1) it kicks me out as being the operator several times an hour even though I don’t have guests who are trying to share my scope; (2) the Wi-Fi connection between my scope and my phone is not stable and I have to reconnect a lot; and (3) the overlays placed on the images often misidentify the image as being whatever celestial object I am currently slewing to.

Amazing App for an Amazing Telescope

The Unistellar app is the companion app for the Unistellar eVscope (4.5” telescope). While the scope has the amazing ability of light gathering, the app is what controls and literally makes observing so easy with the scope. Using GPS from your phone through the app, the scope determines the scope's location so that utilizing it's star database it can easily align the scope in under a minute so observing can begin.

Within the app there are five areas, the observing screen; the deep sky object database for selection; Citizen science; saved image review and settings. Each function very well and make observing deep sky objects very simple and easy - even from the middle of large cities.

The combination of this app with the Unistellar eVScope is revolutionary. To be able to turn a telescope on, have it figure out what part of the sky it is pointed at, and from there point to any other object in the sky is amazing. Add to that the enhanced vision, essentially real time long exposure stacking by the telescope and you have a revolutionary telescope. I have seen and photographed more objects with this scope in 3 months than I have in the past 30 years with “go to” scopes. And being able to see objects in color, in real time, rather than the faint gray blobs in traditional visual astronomy, is very rewarding.
