The mirror is extremely light and thin but the glass ribs beneath minimise the glass deformation, thus allowing continuous high performance from all the telescope angulations. Also, the small thickness of the mirror allows a much quicker cooling time compared to the standard monolithic mirrors. The secondary mirror has a honeycomb structure that follows the concept of the primary mirror: lightweight, rigid and quick to cool down.\u003c\/p\u003e\n\u003cp\u003eBoth the mirrors are aluminised and in order to protect the reflective treatment over the years, the coatings are protected by a thin layer of quartz (silicon dioxide).

triplet refractor\u003c\/strong\u003e with the \u003cstrong\u003ehighest possible correction of any refractor on the market\u003c\/strong\u003e. The unique optical configuration based on a highly air-spaced triplet completely \u003cstrong\u003eeliminates spherical aberration\u003c\/strong\u003e while having the best chromatic correction in the Takahashi range.

Due to its \u003cstrong\u003eextraordinary correction\u003c\/strong\u003e, the TOA-130 also excels at high resolution planetary imaging.\u003c\/p\u003e\n\u003cp\u003eTypical apochromatic refractors are corrected for chromatic aberration at the expense of increasing spherical aberration at certain wavelengths. The TOA's unique design eliminates this problem, with \u003cstrong\u003eless than 0.01mm focal shift across the visible spectrum\u003c\/strong\u003e - 1\/100th less aberration than typical apochromatic designs!\u003c\/p\u003e\n\u003cp\u003eA selection of \u003cstrong\u003ethree different field correctors\u003c\/strong\u003e are available to suit different applications (sold separately).
