New feature is added to make sure Astronomy reach's even to those who are low in budget.So used items related to astronomy section is added in site.
Astronomical Telescope Mirrors are polished and figured to yield high-level performance. Each mirror is aluminized and hard over coated with a protective overcoat, ready for placement in the telescope tube. All mirror surfaces are free of any defects which affect performances. Special types of equipment and techniques make the system mirror the least expensive to any other comparable coated mirror.
Our parabolic telescope mirror size ranges from 4" to 16", all of these mirrors are made from variety of materials like float, borosilicate ( pyrex ) / BK7, quartz and zerodur on special demand quality optical glass.
All telescope mirrors have an aluminum reflective coating, reflectivity is approximately 93%. The aluminum coating is protected by a properly applied protective coating (SiO2).

All glass are circular cut. Perfect circle also available if demanded.
Astronomical Secondary mirror Elliptical of 1/6 wave or better
Astronomical Secondary mirror Elliptical of 1/6 wave or better
Secondary flat mirror 1/6 wave (DIAGONAL) are optically flat yield optimum performances when combined with above astronomical mirrors. Each mirror is aluminized and over coated.
All mirrors have an aluminum reflective coating of 93%. The aluminum coating is protected by a silicon oxide over coated to make the layer durable against aging effects.

Why zerodur?
Why zerodur?
ZERODUR® glass-ceramic has been one of SCHOTT's most unique and extraordinary products for over 50 years. With an extremely low-thermal-expansion, it's essential for a large number of demanding high-tech applications requiring exceptional precision.
Why quartz?
Why quartz?
Quartz glass is fused silica—a very pure glass with an extremely high melting point. Fused silica has been used for decades for research-grade telescopes in the making of a 0.5 to 3-meter size telescope range. Quartz, however, has been traditionally far too expensive for the amateur market. Our mission is to bring quartz to the amateur market at an affordable cost.
Quartz is stronger than Pyrex (borosilicate glass)
Quartz is stronger than Pyrex (borosilicate glass)
Another significant advantage with quartz is the expansion due to thermal absorption is six times less than Pyrex, which has been the gold standard in mirror blanks for years. This means your telescope will be producing sharper images while your neighbor is still trying to cool down and stabilize his mirror.
