A Telescope Tour


For the past few days, I’ve done a lot of talking about differences between types of telescopes and mounting systems. On occasion, I’ve mentioned some of their parts, though I haven’t focused on that.

Today, I will.

This post is meant to be a brief overview of differences between telescopes and their parts. If you want some more in-depth explanations, I’ll link back to those I’ve already written.

In the image above, you see just a few different examples of telescopes. And just in this image, they range far and wide. Most stand on tripods, but some don’t. I can see two different telescope shapes. Some have the eyepiece in different places.

There are more variations of telescopes than are shown here.

So climb on board…I’m about to take you on a telescope tour! Continue reading

Improved Reflecting Telescopes


Can you tell the difference between these two telescopes?

I’ll give you a hint. They are both reflectors. I know I wrote before that you’ll normally find the eyepiece (the little bit tacked onto the telescope tube) on the side with reflectors, but as you can see here, this isn’t always the case.

Here’s another hint. The mounting setup isn’t the difference I’m talking about. I realize the most obvious difference is probably that one is on a “fork mount” (right) and the other is on an equatorial mount (left), but I’m thinking of something related to the optics.

Don’t worry, we’ll talk about these two mounting systems in a later post.

So, can anyone venture a guess and tell me what’s different about these two telescopes? Continue reading
