Details Of The Top Picks For Best Barlow Lens
Owning a Barlow lens in effect doubles the number of eyepieces you have. Let’s say you have two eyepieces in your accessory case, a 10mm and a 25mm. Add a 2X Barlow Lens to the mix, and now you have four magnifications to choose from.
Combining this lens with the 25mm provides double the magnification, or the equivalent of a 12.5mm eyepiece, while the 10mm gives you the power of a 5mm eyepiece.
The most popular Barlow lenses for your telescope tend to be the ones which give either a 2- or 3-times magnification. You can also buy a 5x Barlow lens but depending on the telescope you have, these can present focussing problems and/or a narrow field of view.
For most beginners a good quality 2x power Barlow, or close to that, is recommended
Note: When buying your Barlow Lens, it’s important to get the size which fits the tube of your eyepiece. There are two standard sizes, 1.25 inch and 2 inch. You just have to pick the one that’s right for you.
