The eVscope is a 114mm f/3.9, using a primary mirror identical to scopes like Orion’s StarBlast or Zhumell’s Z114. The primary mirror focuses light directly onto a Sony IMX224 sensor, an uncooled, small sensor used in the ZWO ASI224MC planetary camera. There is no secondary mirror, focuser, ability to install filters, or any kind of field flattener, derotator, or coma corrector. The sensor feeds the image into an onboard computer, which live stacks a series of short (under 30 second) exposures – it can’t take longer exposures due to the alt-azimuth design of the scope’s mount – and feeds them either to your phone/tablet or onto a tiny LCD screen and loupe that mimics an eyepiece. Unistellar calls this whole setup “enhanced vision technology” that makes the telescope “more powerful”, but really it’s just a cheap camera sensor and some very basic live stacking and automatic image processing.
