The telescope rarely works for more than a few minutes without some problem that hangs the observations and control of the telescope. This is on my Galaxy S25. I am sending the Odyssey back for a refund soon.

for such an expensive telescope. it does not stay connected to app, so you keep losing everything, it will stay connected for up to 15minutes sometimes,.then just drops out, all imagery lost, and must restart Odyssey and app to get a connection again.

The app is for the #eVscope telescope and works great! The screen view is just like the scope view. Looking forward to maybe being able to adjust exposure and gain in enhanced mode in the future. Right now you can't. The scope goto and tracking works perfectly. This is a fine all in one telescope which takes about 5 minutes to set up and start using. It is the future and I look forward to it getting better and less expensive as time goes on!

The new version 2.0.1 works quite well, but a first-use tutorial is needed. The features of the earlier version are there, although sometimes difficult to find. For example, to input a location using RA/Dec, you must go to the scope view screen, click the 'Move' button, and then click on the tiny compass icon in the upper right. The full-screen view is nice, as is the ability to save images both with and without the border at the same time. It would be nice if they included all NGC objects.

Use this several times a month for public star parties. Good companion to visual scope I also use at the same time. I used to use a Google Chromebook with a 17 in monitor for the public to see some amazing objects but the recent app update downgraded the chromebook so it no longer works (the scope still communicates with the chromebook in telling the battery level, but no images are transmitted as they had been in the past). Bring back the chromebook functionality in the next update.

The app is intuitive, simple and easy to navigate. However it was laggin in making WIFI connection. The wifi connection drop unexpectively a few times during one observation. APP info was not clearly indicate that it needs a GPS/Celluar model. Tablet with A-GPS, GLONASS is not compatible with the app. The storage is not cleared after images was uploaded. This issue was reported to tech support a few days ago, but still no respons from tech support. Tech Sup was slow in respond.

Version 1.4.1 The evscope provides in a few minutes quite impressive pictures of nebulae and galaxies even in a big city. Despite regular updates, there's stil connectivity issues (eg. Operator/watcher, connectivity drops). It would nice to be able to download raw data of the pictures for postprocessing instead of compressed pictures. Also, why don't give the option to save the full frame pictures with the informations provided in the round ones?
