Lunt Mini-SLF Feather Touch Focuser (1.25”) for LS50T

• Purpose-built upgrade for the Lunt LS50T (and any scope using a helical focuser); drop-in replacement that matches the exact envelope of the stock unit

• Feather Touch feel, 1.25" format: ultra-smooth coarse focus for confident, repeatable dialing-in (note: no 10:1 micro reduction on this model)

• Hardened stainless-on-stainless running surfaces for superior smoothness, longevity, and wear resistance—ideal for CCD/CMOS imaging and critical visual work

• Ultra-low backlash system (0.0 mm) and 0.01 mm repeatability for razor-sharp focus control on prominences, granulation, and night-sky targets

• Rotatable body for easy imaging train framing; adjustable tension + lock to hold focus through long exposures

• Glare-resistant black internal baffling preserves contrast in H-alpha and broadband setups

• T2-threaded drawtube integrates filters and accessories cleanly; accepts standard 1.25" nosepieces

• Built to last: precision stainless steel, steel, and aluminum construction with nylon-tipped set screws gentle on eyepiece barrels

• Optional accessory for the LS50T; sold separately to upgrade stock helical focusing to a premium rack-and-pinion experience
