We have not planned to offer a camera adapter for a simple reason. The eVscope is a connected device, everything you observe through the eyepiece will be available, and downloadable, at the same time on your smartphone.
The experience we are designing is an all-in-one digital telescope, this is how we can achieve both ease of use and optical power, as of today we have no plan to turn it into a plug-in for other telescopes.
The eVscope's eyepiece is perfectly optimized for its optical setup and you will be able to adjust magnifications digitally at 50x 100x and 150x. So there is no need for an additional eyepiece.
