The Celestron Power Tank: The Perfect Portable Power Pack for Your Telescope

If you’re reading this review we know that you’re already interested in astronomy so you know who Celestron are. What you might not know is that Celestron were originally known as Valor Electronics, and they produced a lot of electronic components for the US military in the 1950s. In a weird twist of fate Tom Johnson, CEO of Valor, decided to build a telescope for his sons as a treat and by the late 1950s it was obvious that the future of Valor lay in designing telescopes for amateur astronomers instead. Obviously “Valor” doesn’t really scream astronomy at you so the company was rebranded to Celestron in the early 1960s.

Although you already know that Celestron manufacture a pretty impressive range of telescopes you might not have noticed they also manufacture a range of astronomy accessories too. The Celestron accessory we’re going to take a look at today is the Celestron Power Tank – their external battery pack for computerized telescopes.
