The solution to these fundamental problems could be quite simple, according to experts at the University of Utah. Their proposal is to replace curved lenses with a large aperture flat lens.

A fully electronic, motorized alt-az mount telescope the Unistellar eVscope 2 is as beautiful as it is functional with instant access to the cosmos.

In the early 1600s, Dutch spectacle maker Jan Lippershey discovered that combining lenses could magnify distant objects.

DwarfLab Dwarf 3: Design & Handling. The Dwarf 3 is tiny, but not especially lightweight. At 2.87lb/1.3 kg, in the hand, it feels like the equivalent of holding a heavy wide-angle lens.

The eVscope 2 telescope is meant for more experienced astronomers, featuring a Nikon-developed eyepiece (with enhanced contrast, a deep black image, and an array of lenses) and a higher image ...

The telescope began as a relatively simple device, born out of optical experimentation. It combined a series of lenses and mirrors to collect and magnify light, allowing the user to see far away ...

The first lens is relatively close to the source, with a distance estimated at 10.2 billion light-years. What happens is that the quasar’s light is magnified and multiplied by this massive galaxy.
