10mm Telescope Lens
A 10mm telescope lens will provide you with a very clear view of the moon. It offers the highest power possible for a given telescope, allowing you to see the most detail and features. This is great for those who want to observe lunar features in detail, such as craters, mountains and valleys.
However, a 10mm telescope lens will also give you the narrowest field of view. This means that you won’t be able to see a lot of the moon at once, making it difficult to spot larger features or patterns.
20mm Telescope Lens
A 20mm telescope lens offers a much wider field of view than the 10mm lens, allowing you to see more of the moon in one go. This is great for those who want to observe the moon’s larger features and patterns, such as the dark and bright regions that make up the “Man in the Moon” pattern.
However, the 20mm telescope lens also has a lower power than the 10mm lens, meaning that you won’t be able to see as much detail. This makes it less suitable for those who want to observe the moon’s finer features.
In summary, it really comes down to what you want to observe. If you’re looking for detailed features, such as craters and mountains, then a 10mm telescope lens is the best choice. However, if you want to observe the moon’s larger features and patterns, then a 20mm telescope lens is the better option.
No matter which one you choose, both lenses will provide you with a clear view of the moon and are great for lunar observation. So make sure to consider what you want to observe before making your decision.
