This 0.8X focal reducer/field flattener is designed specifically for prime focus astrophotography with the SVBONY SV550 122mm f/7 apo refractor. The fully-multicoated reducer/flattener converts the 854mm focal length f/7 refractor into a 683.2mm f/5.6 system for faster and wider field astronomical and terrestrial photography. In addition to reducing the focal length of the telescope and thereby increasing the photographic speed, the flattens the normal field curvature inherent in refractors. This provides images that are sharply focused out to the corners of DSLR and CCD imaging chips. The reducer/flattener threads into the focuser for a secure connection.  The threading is metric 63x1. Back focus is 55mm from the shoulder of the reducer to the image plane, the standard spacing for DSLR camera bodies.

At full resolution, the camera frame rate of SV505C can reach 93fps, and more frames can be captured at the same time. Especially in the case of bad weather, the shooting can be completed quickly by using the shooting gap time;

SV505C has a QE of about 80%. It has extremely high sensitivity in the near-infrared region and extremely high signal-to-noise ratio in the dark environment. It is very suitable for photographing the surface details of Mars, Jupiter, Saturn and other solar system planets and the moon. The camera has extraordinary sensitivity in the infrared band;

The SV505C has a 1 / 1.8 "frame, and the chip area is 7.9mm * 4.5mm, which means that the photosensitive area is almost twice that of the sv305 pro. With the same telescope, a larger area can be photographed.
