I telescope that sees into the past

So lets say you have a telescope, binoculars, microscope, w/e. Light enters and gets refracted, reflected a couple of times or whatever. Now lets say you have thousands of micro mirrors perfectly aligned so that it causes the rays of light to bounce around for about 15 minutes. After they finally finish bouncing off mirrors in the device, it now exits the device. If you looked at it at this time you would see 15 minutes into the past right.

it takes 8 years for the light to reach us from the sun.
