A 2X Barlow is one of the most popular telescope accessories available because it doubles the magnification of any eyepiece with the same barrel size! Since this is a 2” 2X Barlow with a 1.25” adapter, it will work great with both 1.25” and 2” eyepieces. Grow your magnification choices quickly by adding a good 2X Barlow to your accessory case.

The Apertura 10 mm eyepiece will produce medium power views of 71X when used with the FCD100 102mm Triplet. Add a 2X Barlow and double the power to 142X, which is great for higher power views on most nights.

A low power eyepiece is an essential part of any amateur astronomer’s bag of tricks. This 15 mm eyepiece will produce 48X magnification when used with the 102 mm triplet refractor. Add a 2X Barlow to the mix and get 96X.
