Describe

Features:

1. SVBONY M54x0.75 0.8x focal length reducer and flattener for refracting telescopes.

When paired with SVBNOY 70f6 ED, the focal ratio is shortened from f/6 to f/4.8. After focusing, you can capture a wider starry sky, finer stars, and better signal-to-noise ratio under the same exposure.

3. By using advanced refractors, dazzling celestial photos can be taken without worrying about star distortion at the edges of the photos.

4. The installation of multi-layer coated optical components in highly polished and hard anodized aluminum bodies helps to reduce weight.

5. The front end is connected to the main lens through an M54x0.75 socket, and the back end is connected to the camera mount through an M48x0.75 threaded connection (supports full frame cameras)

6. The default back intercept is 55mm. Use the 360 ° field of view rotator at the end of the focusing tube (sold separately) to meet your composition requirements without the need to rotate the main lens, and also to meet the use of filter wheels/OAG/astronomical cameras
