The planets are very small objects to look at, and you need the highest magnification that your telescope can handle to see the […]

Barlow Lens vs Eyepiece – Magnification Battle

If you are looking for higher magnification with your telescope, you have two options: buy the Barlow lens or get a shorter eyepiece to your collection. But what is a better option to increase the magnification? Barlow lens or the eyepiece? They both have their advantage and disadvantage. Barlow lenses are a better option if […]

Schmidt Cassegrain vs Maksutov Cassegrain – Where Is The Difference?

The Cassegrain design is very popular amongst amateur astronomers, and almost every amateur astronomer will own, at some point in life, the Cassegrain design telescope. We have to types- Schmidt(SCT) and Maksutov(MAK). The main difference between the Schmidt Cassegrain and the Maksutov Cassegrain is the corrector lens at the front of the tube and secondary […]
