Why A Newtonian Telescope Is A Good Choice For Astronomy
http://www.astronomyhints.com/newtonian.html
This site describes the features of the Newtonian telescope, one of the simplest and cheapest telescope designs made for astronomy. And yes, it is named after Isaac Newton, who invented the design. I admit I'm partial to this inexpensive and capable design. Given its capabilities versus its price, it provides the best overall seeing for the dollar. My 6 inch f/5 Newtonian, similar to the Celestron Advanced Series C6-NGT - Telescope - 150 mm - f/5.0 - Newtonian reflector. Page, show a puzzling finding rel...

How Does a Secondary Affect Telescope Diffraction?
http://www.astronomyhints.com/spider.html
Diffraction: What is it? If you've probed into purchasing a telescope for very long, you've probably ran into the term diffraction. Especially when discussing reflecting type telescopes. I cut my teeth on reflecting telescope, learning much from my old copy of Making Your Own Telescope (Dover Books on Astronomy). Still considered one of the best telescope making books out there. Many of the concepts introduced here are covered in more detail in Making Your Own Telescope. Diffraction and the Refractor.

Why You May Need A Barlow Lens
http://www.astronomyhints.com/barlow.html
Learn How A Barlow Lens Works, And See If You Need One. How The Telescope Objective Works. The purpose of the objective is to take incoming light from a distant source and bring it to a focus. In the diagram, light from a desired target enters from the left, and is bent to a focus on the right. An eyepiece placed at the focus will create an image for the observer's eye. Magnification = Objective FL / Eyepiece FL. But - if you happen to have a relatively short telescope, one only 20 to 40 inches in focal ...

What's An Apodizing Screen? How Does It Affect Diffraction?
http://www.astronomyhints.com/apodize.html
The Apodizing Screen Tutorial. Dealing With Diffraction In Telescopes. At left is a computer simulated image of a star as seen at high power through a telescope. Based on the Huygens Principle, the image was created by forming a unit gain circle in 3D to represent a circular aperture, then performing a 2D Fourier Transform on the pattern. The result is the interference pattern shown here, and it represents a point source (star) as seen through a telescope. Limits the resolving power of a telescope. The p...
