The NexStar 114 SLT's compact Newtonian optics produce pictures this are three times brighter than 60mm beginner scopes. Together with this telescope it's simple to see Saturn's rings and Jupiter's cloud belts. When the night air is still and clear I've been effective to see the Cassini division in Saturn's rings and even spot the shadow of Jupiter's moons crossing the planets cloud tops! Deep space objects like star clusters and galaxies in addition show up nicely. The Ring Nebula M57, for instance, shows up as a pale smoke ring, and globular cluster M13 begins to reveal its unique stars.
Celestron's computerized SkyAlign system is amazingly fast and simple to use. If you can see the moon, you can align this telescope! When you turn on the telescope, pick and choose "Solar System Align" on the hand control, enter the date and time, point the telescope at the moon, and press the "Align" button. This's all it takes; the computerized tracking system takes over and begins tracking, quietly, and accurately. Experienced users will love the "Auto Two-Star Align" and "SkyAlign" modes for the reason that they agree to the telescope to point accurately at over 4,000 objects in the NexStar database. The accurate tracking allowed me to use a Celestron NexImage to get some nice shut-up images of the moon and planets.
The biggest drawback to a computerized telescope is its battery consumption. The standard AA batteries only last a few hours, but the NexStar 114 SLT works very well together with an external 12-volt battery such as Celestron's Power Tank. The other drawback comes from the NexStar 114 SLT's compact optical design. This telescope uses a short-focal-length mirror combined together with a corrector lens to simulate a traditional long tube reflector. This works pretty well at moderate magnification levels, but the mirrors may want to be fine-tuned, or "collimated," to get the excellent high power pictures. I locate Celestron's Collimation Eyepiece helps me get this fine tuning just right, but the reward is sharp pictures, even when I use the high power 9mm eyepiece together with a barlow lens for a magnification over 200x. --Jeff Phillips
