98mm RD-EXT 33.2mm (TKA86205)

The threads are precise and the anodizing matches perfectly with my other Takahashi gear. I’m getting sharp, round stars across the whole frame now that I can dial in my backfocus exactly.

This extension ring threads on smoothly and securely, giving me exactly the back focus I needed for my camera sensor. The 33.2mm length is perfect for achieving proper spacing with my reducer, and it feels solid and well-machined.

The 33.2mm extension spacing sits perfectly between my imaging train components, and the fit onto the 98mm thread was snug without any play. I've used it on two clear nights so far and my back focus has been spot-on for crisp star shapes. This little adapter does exactly what it's supposed to do.
