The Astronomy Mirror range covers 12 catalogue items. Models in this range include D305F1200 305mm Telescope Main Mirror Parabolic Primary Mirror Large Diameter; D203F1600 Newton Reflector Objective Primary Mirror Astronomical Telescope; D150F750 Parabolic Reflector Spherical Primary Mirror for Astronomical Telescope; D130F650 Newton Reflection Primary Mirror for DIY Astronomical Telescope. Every item is listed with the specification published for it, so a model can be compared on working distance, magnification, interface and fitment rather than on a description.

더 보기What Goes Wrong Without the Right Astronomy Mirror
- A mismatched primary mirror causes spherical aberration and blurry images at the focal plane
- A secondary mirror with incorrect minor axis dimension cannot align properly with the optical axis
- An uncoated or poorly coated mirror reduces light reflection and lowers image brightness
- A mirror with insufficient edge thickness may crack under thermal stress during telescope use
- Incorrect focal length prevents proper eyepiece or camera focus in the optical train

자주 묻는 질문
What is the difference between a parabolic and spherical primary mirror?
A parabolic mirror corrects spherical aberration and focuses light to a single point, while a spherical mirror introduces slight aberration but is easier to manufacture and suitable for shorter focal ratios.
Can I use a secondary mirror from another brand with these primary mirrors?
Only if the minor axis dimension and shape (elliptical or plane) match the primary mirror's design. Mismatched dimensions cause misalignment and image distortion.
What does 1/6 PV mean in mirror specifications?
PV stands for Peak to Valley, a measure of surface accuracy. 1/6 PV means the mirror surface deviates from the ideal shape by no more than one-sixth of a wavelength of light, indicating high precision.
Are the mirrors coated before shipping?
Yes. All mirrors are aluminized with a protective silica film to prevent oxidation and maintain reflectivity.
Can I order just the secondary mirror without the primary?
Yes. Secondary mirrors are sold as standalone components in this category.
