AstroZap 鋁製 8 吋 SCT 防露蓋 - AZ-300

I was worried light leaks would ruin my long-exposure shots, but this cap blocks everything perfectly while still leaving easy access for focus knobs. It's solid aluminum, so no flimsy plastic here.

This cap fits snugly right over my dew shield and clicks into place perfectly—no more fumbling with separate covers in the dark. It's been keeping out stray light and moisture during long observation sessions, exactly what I needed.

Been out three nights in a row and the dew shield cap snaps on snug every time, no wobble. It blocks stray porch light from the neighbor's floodlight completely, so I'm not re-aiming between targets. Solid aluminum build feels like it'll outlast the scope.
