Features:
1. The defocuser and collimator of SVBONY 2 0.8x refracting telescope can meet the illumination requirements for full frame shooting.
When paired with SVBNOY 102ED, the focal ratio is reduced from f/7 to f/5.6. After focusing, a wider starry sky can be captured with finer star points, and the signaltonoise ratio is better under the same exposure.
3. By using advanced refracting mirrors, dazzling photos of celestial bodies can be taken without worrying about distortion of star points at the edges of the photos.
5. Includes standard 2 filter threads to add the light pollution filter you need.
7. The default intercept is 55mm. Using the 360 ° field of view rotator at the end of the focusing tube (sold separately), you can meet your composition requirements without rotating the main lens, and also meet the needs of filter wheels/OAG/astronomical cameras
