I didn’t truly grasp how vast the night sky is until I tried to pick out particular stars with a telescope. If you’re only slightly off, you end up being way off! The 90SLT combats this problem with a built-in computer that automatically moves the telescope by itself to take you to the stars you want to see (it can locate more than 4 000 celestial objects). The tricky part is initially aligning the telescope with any three bright celestial objects (you don’t need to know what they are). This set-up takes some practice (and drains batteries quickly, so rechargeable ones are recommended), but it does get easier after a few attempts. The motorised mount then tracks the object across the sky, ensuring you can keep your eye on something over a long period as it moves. The aperture is 90mm, which means the clarity is not as good as the Lightbridge’s, but for locating objects in the sky there’s no contest.
TIP When it comes to buying a telescope, don’t skimp on quality. Look for two things: a sturdy mount and high-quality optics.
