D127F900 Newton Reflection Primary Mirror for DIY Astronomical Telescope

Key Benefits

• 127mm aperture provides sufficient light gathering for deep-sky and planetary observation
• 900mm focal length offers a moderate focal ratio suitable for both wide-field and detailed views
• Spherical primary mirror simplifies fabrication and alignment for amateur telescope makers
• Aluminized surface with protective film ensures high reflectivity and long-term durability
• Compatible with standard Newtonian telescope designs, enabling custom builds from scratch

Application Scenarios

• Building a Newtonian reflector telescope from components for personal or educational use
• Replacing a damaged primary mirror in an existing DIY telescope setup
• Constructing a telescope for astrophotography with a custom mount and tracking system
• Using in a university or school workshop for hands-on optics and telescope assembly projects
• Integrating into a telescope kit for hobbyists who prefer assembling their own instruments

Who It Is For

• Amateur astronomers building telescopes from scratch
• Educational institutions teaching optics and telescope mechanics
• Hobbyists working on DIY telescope projects with custom mounts
• Workshop instructors guiding students through telescope assembly
• Enthusiasts upgrading or repairing their existing Newtonian telescope

Problems It Solves

• A standard spherical mirror is easier to fabricate and test than a parabolic one, reducing build complexity
• Aluminized and protected coating prevents oxidation and maintains reflectivity over time
• Clear specification of focal length and aperture allows accurate optical design and alignment
• Standard secondary mirror size (35mm minor axis) ensures compatibility with common Newtonian configurations
• Component-level mirror supply avoids the need to purchase a complete telescope for testing or repair

Technical Features

• Spherical primary mirror with 127mm diameter and 900mm focal length
• Aluminized surface with protective film for high reflectivity and corrosion resistance
• Secondary mirror is an elliptical plane with a minor axis of 35mm
• Designed for Newtonian reflector telescope optical systems
• Intended for use in DIY telescope builds, not as a complete instrument

• Compatible with standard Newtonian secondary mirror mounts and holders
• Can be used with optional focuser and tube assembly from the same supplier's range

Comparison With Other Options

Use Guide

• Ensure the secondary mirror holder is compatible with a 35mm minor axis elliptical mirror
• Use a collimation tool to align the primary and secondary mirrors after assembly
• Handle the mirror only by the edges to avoid fingerprints on the optical surface
• Clean only with compressed air or a soft brush; avoid direct contact with the coating
• Store in a dry, dust-free environment when not in use to preserve the protective film
