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
