Photo Tube Extension DT (TKP20006B)

The threads are machined perfectly smooth, so attaching it to my photo tube was effortless and wobble-free. It adds exactly the right extension for achieving focus with my camera setup.

I was worried about vignetting with my longer focal length setup, but this extension tube eliminated it completely. The anodized finish matches my other gear perfectly and slides on without any resistance.

I’d been struggling with focus on my imaging setup, but this tube extension gave me just the right spacing to achieve crisp stars. The build quality is typical of high-end accessories—solid and precise. My only surprise was how much of a difference those few extra millimeters made.
