مخفض 0.66x CDK12.5 /14/ 17

Swapping this reducer onto my CDK12.5 was straightforward, and the f/5.3 focal ratio really opens up shorter exposures. The first test shot showed noticeably tighter stars across the whole frame than I'd get without it.

I was worried about losing image quality, but the 0.66x reduction kept everything sharp while cutting my exposure times in half. Perfect for getting those faint nebulae with my f/8 scope.

Cut my exposure times nearly in half after screwing this onto the CDK12.5 — the f/5.3 speed really shows on faint nebulae. Stars stay round to the corners, which I was honestly worried about at this reduction. Focusing was a bit touchy at first, but once dialed in it's been flawless.
