Night Optics Calibration

My round belly slid across the entryway runner and heaved up onto the low wooden windowsill overlooking the courtyard. Coo... Resting near the curtain fold was a pair of heavy vintage field binoculars, their black enameled barrels cool to the touch. A proper sentry returning from evening maneuvers must calibrate night optics! Bracing my side flippers against the painted sill, I pressed my snout against the knurled brass center wheel. With two careful nudges, the dial turned with a crisp metallic click, aligning the twin lenses toward the amber streetlamps below. Bark! I rested my chin squarely between the eyepieces, standing vigilant watch over our peaceful perimeter.
