أنبوب تمديد 60 مم لمُركّز FT 3 بوصة (STE-M109-060)

Threaded right onto my Feather Touch without any slop, and the extra 60mm gave me just the back focus I needed for my imaging train. The machining is precise and clean.

Finally got this 60mm threaded extension to dial in the back focus on my setup and it clicked right into the Feather Touch focuser without any wobble. The extra distance made all the difference for my field flattener and the threads are buttery smooth.

This extension tube threaded onto my Feather Touch perfectly—the machining is precise with no cross-threading issues. Gave me exactly the back focus I needed to reach focus with my reducer.
