  In this paper we present the Adaptive Optics Lucky Imager (AOLI), a
state-of-the-art instrument which makes use of two well proved techniques for
extremely high spatial resolution with ground-based telescopes: Lucky Imaging
(LI) and Adaptive Optics (AO).
  AOLI comprises an AO system, including a low order non-linear curvature
wavefront sensor together with a 241 actuators deformable mirror, a science
array of four 1024x1024 EMCCDs, allowing a 120x120 down to 36x36 arcseconds
field of view, a calibration subsystem and a powerful LI software. Thanks to
the revolutionary WFS, AOLI shall have the capability of using faint reference
stars ({\it I\/} $\sim$ 16.5-17.5), enabling it to be used over a much wider
part of the sky than with common Shack-Hartmann AO systems.
  This instrument saw first light in September 2013 at William Herschel
Telescope. Although the instrument was not complete, these commissioning
demonstrated its feasibility, obtaining a FWHM for the best PSF of
0.151$\pm$0.005 arcsec and a plate scale of 55.0$\pm$0.3 mas/pixel. Those
observations served us to prove some characteristics of the interesting
multiple T Tauri system LkH$\alpha$ 262-263, finding it to be gravitationally
bounded. This interesting multiple system mixes the presence of proto-planetary
discs, one proved to be double, and the first-time optically resolved pair
LkH$\alpha$ 263AB (0.42 arcsec separation).
