Used Celestron C-5 Astro-Black
The C5+ is a Schmidt-Cassegrain telescope, or SCT, with a 5-inch aperture, made by Celestron (formerly Celestron International). The answer, in a word, is portability. Even at 23 pounds, the C5+ was portable in a way that the C8 couldn't match.
It's interesting to note, however, that that wasn't always the intended appeal of the C5+. It began life as the C5 in 1971, just one year after Celestron had started the SCT craze with its C8. In the 1970s, dark skies were not nearly as rare as they are today, at the start of the 21st century, and one didn't necessarily have to drive out to the boondocks in order to observe effectively. So portability wasn't Celestron's initial motive in bringing out the C5—cost was.
But the C5 manufacturing process was dogged by unexpectedly high costs right from the beginning. Celestron had designed the C5 by essentially photo-reducing the C8 blueprints, down to using a scale version of the C8's dual axis, AC-powered spur-gear drive. The C5 also inherited the C8's orange tube, twin-arm fork, and uncoated OTA. Although this design resulted in lower materials costs, the tolerances for each part were correspondingly tighter as well.
