    OK, here is the Bible according to Celestron SLT scopes.
    When the scope is working, it's fantastic (see below if you have a non-working scope with a boot loader failure). The Newtonian design is comfortable to look through - the eyepiece is at the front of the scope, and it is positioned around eye-level when standing. Newtonian optics are also simple, which keeps the cost down (and minimizes light lost to lens absorption).
    The optic properties of this scope are outstanding. The 650mm focal length and 150mm (about 5-1/8") aperture are great specs, especially when paired with the highly-recommended Celestron accessory kit (Celestron Model 94303, available on Amazon). The scope comes with a 9mm and 25mm eyepiece, for magnifications of 72 and 26 power (magnification is focal length divided by eyepiece length, so magnification increases as focal length increases, and decreases as eyepiece length increases). The big 130mm aperture of this scope gives the scope a maximum useful magnification of about 307 power, using the rule of thumb that you can magnify 60 times for each inch of aperture.
    At a focal ratio of f5, this is a fairly "fast" scope, meaning it lets in a lot of light for it's focal length. The f-number is the focal length divided by the aperture size, and the lower the f-number, the faster the scope. Faster is (generally) better. F-numbers will be familiar to photographers, and telescopic "lenses" operate on the exact same concept as fast photographic lenses. In photography, a lens is "fast" because it allows a shorter shutter speed (because it lets in more light), meaning you can capture faster motion that would be blurry with a longer exposure (as would be required by a "slower" lens).
    The auto-orientation works like magic, but it's better to give it very precise time and location. Use a GPS for location; don't just tell it what city you are in (you can choose your location input method). For some reason, the controller can remember your last location and the time zone of your previous observation, but the controller does not keep time when it is switched off, so you must enter the (exact) time again whenever you switch the power off and back on (C'mon, Celestron - seriously?)
    You can orient the scope by pointing the scope at ANY three bright objects (you do not need to know what they are) or two objects if you know what they are (but this is said to be less precise). The scope must be level (it has a built-in level bubble). Although this scope is not really classified as a "beginner's scope," it is great for beginners - you don't need to know anything to begin viewing amazing things, and a beginner will not "outgrow" this scope anytime soon. The only comparable computerized Newtonian scope that I could find in this price range is the Orion StarBlast 6i IntelliScope, but it is available only with a table-top mount (???). If that Orion scope (750mm focal length, 6-inch aperture) was available with a sturdy tripod mount in this price range then I would be writing this review for that scope, because I would have bought that scope instead, without a doubt. Orion lost my business because they expected me to have a study TABLE available at each observation site.
    The optional Celestron accessory kit includes (among other things) 6mm, 8mm, 13mm, 17mm, and 32mm eyepieces and a Barlow 2X adapter. With a 6mm eyepiece and a Barlow 2X adapter (which effectively doubles the magnification of the eyepiece, making it a 3mm focal length), the scope can achieve a magnification of 216 power (pretty respectable). You could purchase shorter eyepieces or a 3X Barlow to push the magnification near the 307 power limit, but I don't think you will find yourself wanting to do so - you will be amazed at what you can clearly see (the bands of Jupiter and its Galilean moons, the rings of Saturn, etc). Note that the 307-power limit cannot be exceeded with eyepieces or Barlow lenses - the image will be pretty much worthless if you try to exceed this limit, which is a function of how much light the scope can gather (which is determined by the aperture size). As you approach this limit, the image quality decreases, so you will probably find images much more satisfying at low-to-mid-200 power than you would at theoretical maximum 300+ power.
    The gray moon filter in the accessory kit is especially useful for bright objects (such as the moon, of course, but also Venus and Jupiter).

    The 130 SLT is fun, entertaining, easy to use, and an easy to love digital tracking reflecter telescope.
    Even though I make hotspot $500, this would still be perfect gift for any astronomy lover and for novice telescope owners

    The tripod is underrated and takes a long time to stop jiggling after it moves or is bumped.

    How sturdy is the tripod? I've read quite a few reviews claiming it's cheap quality and the legs bow easily.

      I have this telescope and the tripod works great, never had an issue with them!

      Not sturdy enough.
