During your observing sessions, you may have wondered how far a telescope can peer into the cosmic depths or how far we can see with only our eyes. I was wondering about this recently and thought I would investigate it and provide information that others might find helpful. Also included [...]
Accurate focus is a must for rewarding views of astronomical objects. Crayford focusers have revolutionized this process, offering smooth, accurate focusing that’s become the gold standard in modern telescope design. You should consider a Crayford focuser for your telescope. Understanding the Basics The Crayford focuser, invented by John Wall in [...]
This article about the formation of the Moon is quite in-depth. If you would like less technical information on the Moon you may like Why Do We Always See the Same Face of the Moon or Why Does The Moon Shine. The question of the Moon’s formation has been pondered [...]
If you study a photograph of the Moon closely, you may notice what appear to be channels running across the lunar surface. These features are known as lunar rilles.

Below is your observing guide for the months of November and December 2024. While this guide may be useful in the early evening, you may wish to read our current guide, Observing Guide: January and February 2025. As the weather becomes cooler and the nights longer in the northern hemisphere, [...]
There is a clear link between solar activity and effects observed in space directly around the Earth. This space weather results from dynamic events within the Sun’s atmosphere. This article first explores the mechanisms that cause dynamic events in the Sun’s atmosphere before exploring how they affect space around Earth. [...]
Our understanding of stellar processes is based on our understanding of the Sun. We have studied the processes in the Sun and, with astronomical observations, developed models of how stars are born, live, and eventually die. If our understanding of the Sun is incorrect, then so too would our models [...]
