0.8x Reducer Flattener

Sky Rover 0.8x reducer flattener for 130/155 APO PRO can meet the needs of full frame photography.

When the 0.8x reducer flattener is matched with the telescope, the focal ratio is shortened. After focal reduction, the photographed starry sky is wider, the star points are more delicate, and the signal-to-noise ratio is better under the same exposure.

A filter can be installed inside the new 0.8x reducer flattener. The thread of one end is M92×1, and the other thread is M48×0.75, which is for camera bayonet. This end contains the built-in M48X0.75 thread, and the filter can be installed at this thread after the interface with anti-slip texture is twisted clockwise.

The default back focus of the 0.8x reducer flattener is 55mm. By using the 360-degree image field rotator at the tail of the focusing tube can meet your composition requirements without rotating the telescope. And you can use filter wheel /OAG/ astronomical camera at the same time (please use accessories within the intercept range).
