D203F1600 Newton Reflector Objective Primary Mirror Astronomical Telescope

Key Benefits

• 203mm diameter provides a large light-gathering area for deep-sky and planetary observation
• 1600mm focal length delivers a long focal ratio suitable for high-magnification imaging
• Aluminized surface with protective film ensures high reflectivity and long-term durability
• Spherical mirror design simplifies fabrication and alignment for DIY telescope builders
• Compatible with 40mm minor axis secondary mirrors for standard Newtonian configurations

Application Scenarios

• Building a Newtonian reflector telescope from components for amateur astronomy
• Educational projects in schools or universities teaching optical design and telescope assembly
• DIY telescope kits requiring a primary mirror with known optical parameters
• Hobbyist projects focused on astrophotography with a long focal length system
• Replacing or upgrading the primary mirror in an existing Newtonian telescope

Who It Is For

• Amateur astronomers building or upgrading Newton reflector telescopes
• Educational institutions teaching optics, physics or astronomy
• DIY telescope kit suppliers and hobbyists assembling telescopes from parts
• Science outreach programs demonstrating telescope construction and light collection
• Enthusiasts seeking a large aperture mirror for planetary or deep-sky observation

Problems It Solves

• A missing primary mirror prevents a DIY telescope project from progressing
• Low reflectivity or unprotected surfaces degrade image quality and shorten mirror life
• Mismatched mirror dimensions or focal length make alignment and secondary mirror fitting difficult
• Lack of a known focal length and diameter complicates optical system design
• Inconsistent mirror shape or surface quality leads to poor image focus and aberrations

Technical Features

• Spherical mirror shape for simplified fabrication and alignment
• 203mm diameter (caliber) for increased light collection
• 1600mm focal length for high magnification and long focal ratio
• Aluminized surface with protective film for high reflectivity and environmental resistance
• 40mm minor axis (short side diameter) for compatibility with standard secondary mirrors
• Designed for use in Newtonian reflector telescope systems

Comparison With Other Options

Use Guide

• Handle the mirror only by the edges to avoid fingerprints on the optical surface
• Do not touch the aluminized surface; use a clean cloth or air blower for dust removal
• Ensure the secondary mirror is compatible with a 40mm minor axis before assembly
• Align the mirror in the telescope tube with the correct focal length and collimation procedure
• Protect the mirror during storage with a cover or sealed container to prevent dust and moisture
