A gunsight for aiming a firearm may comprise a microbolometer and an objective optic positioned forward of the microbolometer for focusing electromagnetic waves on the microbolometer. The objective optic may comprise one or more objective lenses. The gunsight may also comprise a display and an eyepiece optic positioned rearward of the display for allowing a user to view the display through the eyepiece optic. The eyepiece optic may comprise one or more eyepiece lenses. Circuitry of the gunsight is operatively coupled to the microbolometer and the display. The circuitry may comprise one or more processors and a non-transitory computer readable medium storing one or more instruction sets. In some embodiments, the one or more instruction sets include instructions configured to be executed by the one or more processors to cause the gunsight to capture image signals with the microbolometer and display selected images on the display.
