SKY ROVER 115 mm F/7 APO apochromatic astronomical telescope adopts three-element, air-spaced apochromatic design, including one piece ED glass.

It is equipped dual-speed rack /*C*and*C*/ pinion 2.5-inch focuser, The entire focuser barrel is CNC machined with an anti-reflective internal design /*C*and*C*/ matting paint, providing extra measures to eliminate stray light.

You can use it with a 1x flattener, /*C*or*C*/ 0.8x reducer optionally.

The 1x flattener does /*C*not*C*/ /*C*change*C*/ the telescope's focal ratio itself. The flattener corrects field curvature /*C*and*C*/ coma, resulting in flatter field edges /*C*and*C*/ finer star points.

The 0.8x reducer can bring the 115APO's focal ratio down to F5.6, which has a wider field of view /*C*and*C*/ faster exposure times, making it suitable for capturing large areas of nebulae, star clusters, /*C*and*C*/ faint, fast-moving celestial objects.

115APO adpots a detachable tube, meet the demands of visual /*C*and*C*/ photography. It supports install binoviewer /*C*and*C*/ other accessories.

As visual observers do /*C*not*C*/ require a CAA, to optimize weight, the CAA is sold separately with the flattener /*C*and*C*/ reducer. If you require multiple flattener/ reducers, only one CAA is necessary, please inform our customer service when making a purchase.
