Makatov opposes reflecting telescope.

At present, there are two kinds of folding reflective telescopes that are easy to buy on the market: Schmidt-Ka seglin folding reflective telescope, which is called Zeca for short; Maksutov-Ka seglin type folding reflecting telescope, referred to as Marca. You should ask the latter one.

Maksutov catadioptric optical path was originally a kind of optical path specially used for celestial photography, and its focus was inside the lens barrel near the meniscus correction mirror, so it could only be photographed but not visually observed. Marca combined Maksutov optical path with traditional Ka-seglin reflective optical path, and evaporated a reflective film on the back of the center of the meniscus correction mirror, so that the focus of the whole telescope moved to the back of the main mirror, thus making visual inspection possible. Marca's refractive and reflective surfaces are easy to process and polish, the cost is lower than that of Zeca, and the optical quality is good.

Compared with refractive telescopes, Marca has the characteristics of short lens barrel and long focal length, and is a sharp weapon for observing planets. Its disadvantages are occlusion and double reflection, and the imaging contrast is not as good as that of refractor. When choosing, we should make full use of our strengths and avoid weaknesses according to our own needs.
