J005 2" Telescope Focuser Focusing Mount for Telescope

Key Benefits

• 70mm focusing stroke allows full focus adjustment across a wide range of eyepieces and accessories
• 1:10 fine adjustment enables precise focus control for planetary and lunar detail
• 2'' eyepiece interface with 1.25'' adapter compatibility supports a broad range of eyepieces
• All-metal build resists flex and maintains alignment under variable temperature and load
• 118MM*95MM host interface fits standard Newtonian telescope mounting plates

Application Scenarios

• Adjusting focus on a Newtonian telescope during planetary observation with a 2'' eyepiece
• Switching between 2'' and 1.25'' eyepieces without changing the focuser
• Mounting the focuser on a telescope with a 118MM*95MM interface plate
• Using the 1:10 fine focus for critical focus on high-magnification lunar or planetary views
• Securing a stable focus point during long-exposure astrophotography with a camera adapter

Who It Is For

• Amateur astronomers building or upgrading Newtonian reflector telescopes
• Educational institutions running astronomy labs with student-built or standard Newtonian scopes
• Observing clubs requiring reliable, repeatable focus control for shared telescopes
• Hobbyists doing visual astronomy with interchangeable eyepieces and accessories
• Amateur astrophotographers using a 2'' eyepiece or camera adapter on a Newtonian system

Problems It Solves

• A focuser with no fine adjustment makes it difficult to achieve critical focus on high-magnification targets
• A plastic or low-rigidity focuser can shift during use, breaking focus during long sessions
• Lack of 1.25'' compatibility limits the range of available eyepieces
• A fixed or short focusing stroke prevents use with long focal length eyepieces or camera adapters
• Mismatched interface dimensions prevent mounting on standard Newtonian telescope plates

Technical Features

• Manual focusing with 1:10 fine adjustment for precise focus control
• 2'' eyepiece interface with 1.25'' adapter compatibility
• 70mm focusing stroke for full focus range across eyepieces and accessories
• 118MM*95MM host interface for mounting on standard Newtonian telescope plates
• All-metal construction for rigidity and alignment stability
• Focuser body and drawtube made from solid metal, no plastic components

• Surface finish options available upon request (e.g. black anodized, brushed)

Comparison With Other Options

Use Guide

• Ensure the host interface (118MM*95MM) matches the telescope's mounting plate before installation
• Use the 1:10 fine adjustment to make small focus corrections during high-magnification viewing
• Insert the eyepiece or adapter fully into the 2'' drawtube to prevent light leaks or misalignment
• Check that the 1.25'' adapter is securely seated when using smaller eyepieces
• Clean the drawtube and focus knob periodically to maintain smooth operation
