- 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.

its a reducer. it seems to work.
its a reducer. it seems to work. no issues really.
can get even wider view by using one or two small spacers but don't use too many or too much or you wont have enough inward focus travel
Functionality and quality at a great price.
Perfect with the sv 305 camera and the sv 105 mk. It is helpful that the maksutov is a telescope of high corrected optical. Also works great with high magnification lenses like 5mm on the same sv 105 mk. The images from the camera were compared on the page (astronomy.tools/calculator) and give similar proportions using the ZWO mini 290 as a reference. Same sensor size. For price you can not expect more. For me it is perfect.

1. When the focal length of the telescope is too long to observe a large area of celestial body with low magnification (such as the moon), you can connect the telescope with a focal reducer, shorten the focal length first, and then use a low magnification lens to observe
2. 2 element optical design with fully multi-coated optics
3. Besides the male thread, it also has female thread at the rear end to fit filters
4.. The focal reducer is great for visual use for a bigger FOV and is indispensable when CCD imaging
