- Focal reducer and field flattener is one of the essential accessories for astrophotography; SV193 2 inch 0.8x focal reducer and field flattener for refractor telescopes
- With advanced refractor; SV193 0.8x focal reducer can take dazzling celestial photos without worrying about the distortion of the star points on the edge of the photo
- The front end is a standard 2-inch socket to connect to the main lens; and the back end is M48x0.75 threaded to connect to the camera bayonet; support Full Frame Camera
- Accepts 2 inch filters; includes standard 2 inch filter thread to add light pollution filter you need
- The 0.8 times defocusing system shortens the exposure; it can meet the needs of astrophotographers who need sufficient exposure in a short time
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.
The corrector is suitable for SV550 80F6. 75 filter thread for the use of 2" filters in the camera adapter. Maximum working distance from the M63x1 internal thread: 103 mm - space enough for almost all adaptations.
Notice: Since the SV550 80 APO is designed with f/6 focus ratio. When reducing the focus further, the image quality will not be guaranteed. This is why we produce 1.0x flat field instead of 0.8x.

- 0.5x focal reducer cuts the telescopes focal length in 0.5 times of original's to get a wider field of view
- Fully anti-reflection coatings on all air-glass surfaces for increased contrast
- The focal reducer is great for visual use for a bigger FOV and is indispensable when CCD imaging
- Fully metal structure design;both the ends of the interface part is 28.5x0.6 thread
- Directly connect the interface to the eyepiece;there is a very good performance in both visual and photography
