Bob's Knobs Takahashi Mewlon 210 Secondary Knobs
Bob's Knobs Takahashi Mewlon 210 Secondary Knobs - MEW210
These black plastic knobs with stainless steel threads from Bob's Knobs are a great tool when it comes to collimating your telescope. These specific knobs fit the Takahashi Mewlon 210 telescopes and measure 13mm (1/2") in diameter.
Their small size will allow the factory provided dust cap to fit normally even when the knobs are installed. They also include a set of long spacers so that they can clear the secondary housing lip.
