The 1.25 barrel is internally threaded for use with Alstar 1.25" eyepiece and imaging filters. The inside of the 5x High-Power Barlow's barrel is also glare threaded to help prevent internal reflections.
The Alstar High-Power 5x 4-Element Barlow Lens quintuples the power of any 1.25" telescope eyepiece.
Featuring a high-quality 4-element lens design, the Alstar High-Power 5x Barlow will render exquisite images without introducing additional chromatic abberation while providing a monstrous 5x power boost.
The Barlow lens elements are fully multi-coated with anti-reflection coatings to ensure maximum light throughput for bright, crisp views.
The lenses are also edge-blackened to further maximize contrast and sharpness.
