You then pull off the rubber focus knob, remove the focus assembly cover, take the C-clip or screw off the end of the focus shaft, unthread the stock brass cylinder and bearing assembly, thread the Feather Touch brass stop onto the shaft and put the clip or screw back. Thread the Micro Focuser into the stop, tighten the stop with the wrench, run the focuser down until its base sits flush with the back of the telescope and attach it with the three screws.

The pinion block is internally symmetrical, allowing you to mount it with the fine-focus knob on either the left or right side to suit your preference.

This means ten turns of the fine-focus knob produce the same movement as a single turn of the coarse-focus knob, allowing for exceptionally fine adjustments.

A thumbscrew on the pinion block engages an internal lever, applying pressure to the pinion shaft. This increases the torque required to move the focuser, effectively locking it in place. The brake is adjustable, so you can dial in just enough tension to hold the load while still allowing for fine focus adjustments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eFull 360° Rotation for Precise Image Framing\u003c\/h3\u003e\n\u003cp\u003eFor astrophotographers, composition is key.

For a Newtonian, it typically involves attaching the appropriate curved or flat base plate to the tube. For refractors and SCTs, a threaded adapter screws onto the telescope's rear cell or focuser tube, and the focuser body then attaches to the adapter. The focuser is then turned to the desired position and the set screws tightened.\u003c\/p\u003e\n\u003cp\u003eMaintenance is minimal. The exposed rails and friction plate can be occasionally cleaned with a cotton swab to remove dust and debris. Starlight uses a damping grease on the adjustment thumbscrews; a little WD-40 on a rag removes any that strays, and a liquid car wax used sparingly cleans the outside. Do not disassemble the focuser, as the internal parts are factory-set; doing so could void the warranty.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCrayford vs. Rack \u0026amp; Pinion: Which Starlight Focuser is Right for Your Payload?\u003c\/h3\u003e\n\u003cp\u003eStarlight Instruments offers both Crayford and Rack \u0026amp; Pinion focusers, and the choice depends entirely on your payload.

For a Newtonian where the focuser is horizontal, you may need very little brake tension. However, on a refractor or SCT pointed near the zenith, a heavy 2.0\" eyepiece can cause an un-braked focuser to drift. The adjustable brake allows you to add just enough tension to hold the load securely without compromising the smooth focusing feel.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I switch the focus knobs on the Feather Touch Focuser for left-handed use?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, the pinion housing can be reversed.
