The NexStar 90 SLT package includes everything but the batteries. With a fully illustrated quick set-up guide, no tools are needed to assemble the tele with its steel tripod, motorized , and computer hand control. Two eyepieces are included, a 25mm for 50X magnification and a 9mm eyepiece for 139X. The package even includes the latest version of "The Sky X", software that turns your PC into a virtual planetarium. The Maksutov optical design of the NexStar 90 SLT gives the tele a focal length of 1250mm in an optical tube only twelve inches long. This long focal length is ideal for bringing out detail on the Moon and planets. When I look at the Moon for example, the view is crisp and clear with no trace of false color. When I look at Saturn I can easily push the magnification to 200X with an optional 6mm plossl eyepiece. When I look at deep space objects I often like to use an optional 32mm plossl eyepiece (39X magnification) because objects like M45 the Pleiades cluster and M31 the Andromeda galaxy look better with a wider field of view. The NexStar 90 SLT also features Celestron's patented SkyAlign technology. With SkyAlign I don't need a star chart or a compass to align the tele, I just enter the date and time then point the tele at three bright stars. SkyAlign tells me the star names, and allows the tele to find over 4,000 stars, planets, and galaxies by just pushing a button. The accurate tracking makes it easy to get high power views of the planets, and allowed me to take some great pictures using a Celestron NexImage ( http://www..com/dp/B0002X5Q72 ) webcam. I also like the "Two-Star align" and "Solar System align" modes because I can often get the NexStar system up and running while older s are still waiting for their alignment stars to appear in he twilight. I enjoy using the NexStar 90SLT because it has excellent optics in a compact, twelve pound package that I can carry outside in one trip and be ready to go in minutes. A computerized tele may take practice to set up; if I don't enter the time correctly the alignment may fail for example. The other drawback of a computerized tele, of course, is the short life of standard AA batteries. A rechargeable 12-Volt battery is a handy way to power the NexStar 90SLT, and I like to keep the tripod legs short and observe while seated because this gives me a solid and comfortable view. --Jeff Phillips Pros: * Excellent optics * Compact and portable * Easy computerized go-to tracking * "The Sky X" planetarium software included Cons:* Short battery life with AA batteries Suggested Options: * Celestron Accessory Kit ( http://www..com/dp/B00006RH5I ) * Celestron PowerTank battery ( http://www..com/dp/B00008Y0U5 ) Quarter Moon at 50X with a Power camera Quarter Moon closeup at 200X with Neximage camera Crater Ptolemaeus at 400x with Neximage and 2x barlow Planet Mars at 400x with Neximage and 2x barlow Planet Saturn at 400x with Neximage and 2x barlow
