Refractor telescopes are perhaps the most common and popular type of telescope, known for their simplicity in both setup and use.

Many astronomy enthusiasts begin their journey with observations of the Moon and other planets, which have always been fascinating targets.  The Moon offers an endless array of intricate details—craters, mountains, valleys, and more.  While often thought to be static, the Moon is constantly undergoing subtle changes, such as lunar flashes caused by meteorite impacts.

Observing and sketching planets, on the other hand, is an ongoing challenge.  Unlike deep-sky objects, planets exhibit relatively rapid changes in their appearance.

For telescopes with the same aperture, refractors often outperform reflectors, although this advantage depends on the design and quality of the reflector.  A perfectly crafted long-focus reflector can come close to matching a refractor of the same aperture.  However, reflectors require observation from the front of the telescope tube, making long-focus designs cumbersome to operate.  In contrast, refractors allow for observation from the rear of the telescope, making them more user-friendly.

In response to the suggestions of many classic planetary telescope enthusiasts, Sky Rover Optics has embarked on the development of the 102mm F/11 ED APO, which we have defined as a classic planetary telescope.

The telescope features a detachable two-section tube design, making it convenient for use with a binoviewer and other observation accessories.
