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.

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?
