WHILE THE NAME RIGHTLY implies that the Sky-Watcher Evoguide 50DX was designed as a guidescope, it's more versatile than that. Fitted with eyepieces, it can serve as a high-quality finder and even a small telescope (more about that later). And with the optional Evoguide 50ED Field Flattener ($105), it's a decent wide-field astrograph that performs well with sensors as large as APS format.
