This is the uber-beefy, uber-Everest-like R&P focuser with the Baader adapter installed. Unlike Televue with its racecar knobs and Takahashi with its ultra-light aluminum knobs, these focuser knobs are solid, heavy machined aluminum. The beefiest I've seen. Beefier even than the knobs on the A-P R&P focuser.
Notice the friction brake lever on the right side.
