Nights of Future Passed
Here's a fun look back at some amateur telescopes from days gone by. Some were great, some not so good. I'll leave it up to you to decide which is which!

Brandon Scientific
Development
Although better known for their eyepieces, Brandon also manufactured small achromatic refractors, including this odd looking 3-inch instrument in the late 1940s. Hey, wait a minute...where have I seen that scope before? |

Tinsley Laboratory
Although Tinsley is best remembered for research telescopes in professional and university observatories, they actually started with much more humble aspirations. In 1948 when this ad appeared, they were the leading -- in fact, one of the only -- companies to sell complete telescopes for amateur astronomers. They certainly weren't cheap, however, if you take inflation into account. Not surprisingly, most post-World War II amateur astronomers couldn't afford such extravagant items, and so chose to build their own telescopes instead. |
