A display apparatus includes a plurality of housings connected by adjustable device for setting spacing between centers of the plurality of housings, each housing including: first image source mounted to side of housing; second image source mounted to housing angularly offset from first image source, wherein second image source includes higher resolution and narrower image field of view than first image source; optical combiner positioned in housing between first and second image sources, on which first image from first image source and second image from second image source are superimposed and made visible to user's eye; magnification lens for magnifying second image to increase image field of view; eyepiece lens for reducing focal distance between the optical combiner and the user's eye; and controller configured to control output of second image source to render colors to compensate for distortion and chromatic aberrations introduced by magnification lens.
