The standard Schmidt-Cassegrain Telescope, or SCT, has a medium focal ratio of f/10, making it a jack-of-all-trades; good for terrestrial viewing, enjoying the planets, deep-sky observing, or astrophotography. Their long focal lengths make them particularly good for for distant targets such as galaxies and small nebulae. It features a lightweight, portable design, and since it's easy to use, it's a top pick for beginner astronomers. It has a 2-pier asymmetrical mounting. Although astigmatism can elongate stars off axis, the center of the star remains in a position that keeps it measurable for star positions. An achromatic refractor is designed with two lenses that are therefore only capable of focusing two wavelengths of light, and are usually the most economical. The point is, if you want aperture, portability AND electronics, look into a Schmidt-Cassegrain or EdgeHD telescope in the size you'd like, and then choose whether to have it ride on an equatorial mount and tripod or a computerized alt-azimuth mount and tripod.
