Mechanical Design - Mirror Cells
 |
The primary mirror is precisely aligned with the corrector lenses and permanently bonded in the six-point flotation cell/backplate. This extra care and attention in assembly means you have less trouble collimating the telescope in the field. The heavy-duty, but light-weighted cell/backplate and OTA cradle allow astro-imagers to bolt heavy cameras and filter wheels to the OTA without inducing flexure. Five fans minimize the cool down time of the primary mirror. |
 |
The mirror rests on a six-point cell arrangement, optimized to support the mirror without imparting stress. The five rear fans are removable so the primary can be cleaned while still in the cell. |

CNC-Machined heavy-duty backplate. Bulkhead-inspired construction, with ribs for strength, and milled pockets to reduce weight. |

The entire front end of the astrograph, seen here, can be easily removed from the tube as a single assembly. To avoid flexure of the carbon fiber tube, the robust spider attaches to a heavy-duty aluminum front end ring. |
