Using the K20 eyepiece included as standard equipment, about 45x magnification, it's easy to see the Andromeda Galaxy and its smaller satellite galaxy M32. When compared to 60mm refractors, the Powerseeker 114 brings out much more detail in the Orion Nebula, reveals many more stars in Perseus' Double Cluster and even brings out a few individual stars in globular clusters like M13. Saturn looks quite small at 45x with the K20 eyepiece, but using my own 7.5mm eyepiece (120x) I can easily detect the shadow cast by the planet on the rings, and even glimpse the ring's Cassini Division. When the mirrors are properly lined up or "collimated," the images are reasonably sharp up to magnifications of 225x.
