Essentialシリーズ望遠鏡用T字型ファインダーベース（ネジ付き）(FNDRBASE-ESSEN)

The T-shaped base held my finder scope rock-solid during a night of viewing, and the included screws were exactly the right length. A clean, no-fuss design that does exactly what it's supposed to do.

Screwed this on in a few minutes and it lined up perfectly with the finder scope’s mounting holes, no adjustments needed. The included screws fit snugly without stripping, and the T-shape gives a solid, stable hold. Exactly what I needed to get my telescope set up properly.

This base fit perfectly onto my telescope tube, and the pre-installed screws saved me a lot of fiddling. My finder scope locks in nice and solid now.
