Ashra (All-sky Survey High Resolution Air-shower detector) is a project to build an unconventional optical telescope complex that images very wide field of view, covering 80% of the sky, yet with the angle pixel resolution of a few arcmin, sensitive to the blue to UV light with the use of image intensifier and CMOS technology. The project primarily aims to observe Cherenkov and fluorescence lights from the lateral and longitudinal developments of very-high energy cosmic rays in the atmosphere. It can also be used to monitor optical transients in the wide field of sky. We present the project status, and expected scientific impacts on the observational objectives such as optical transients, unidentified TeV gamma- ray and PeV neutrino sources, and the propagation of EeV cosmic rays.
