中古 - SpaceCat 51mm f/4.9 APO

Picked this up used and the optics are genuinely clean — no scratches or dust I can see. The 51mm aperture pulls in enough light for crisp lunar details even in my light-polluted backyard.

The red body on this first-gen model looks even better in person than the product photos suggested. The optics are spotless and the focus knob turns with a satisfying smoothness that makes me feel like I got a steal on used gear.

I was a bit nervous buying used, but this scope's clean glass and that deep red finish look almost new. The 51mm aperture pulls in plenty of light for crisp lunar views, even with my modest mount.
