7.5mm 廣口轉 T 螺紋轉接器 (TCD0075)

The 7.5mm length is perfect for achieving the right spacing with my filter wheel. I was worried about thread quality, but it screws on smoothly and holds the camera securely. No more light leaks.

Finally got this adapter for my Takahashi scope, and the 7.5mm threading mates perfectly with the Starlight Express camera—no wobble at all. It’s a simple, solid piece of metal that does exactly what it’s supposed to do.

Fits my Takahashi focuser perfectly, and the 7.5mm height clears the filter box without any vignetting. The only reason for four stars is the lack of a locking ring, so I added a bit of thread tape to keep it snug.
