Key Features

The four-lens design with multi-coated surfaces eliminates most of the chromatic aberrations that show up with Barlow lenses having fewer components; A Barlow lens can therefore be a great supplement to your eyepiece collection

The Alstar Barlow lens provides 2.5 times greater magnification; allowing you to observe objects at a significantly closer apparent distance

2.5X Barlow Lens with compression ring this ensures that your accessories are securely attached to the Barlow lens; No screws that might damage your valuable eyepiece instead a gentle but secure grip

It includes a 2 inch to 1.25 inch adapter compatible with 1.25 inch and 2 inch eyepieces as well as other telescope accessories of the same diameter; The M48x0.75 female thread made of hard anodized aluminum can install 2 inch filters with M48x0.75 male thread

Equipped with high-quality optical glass it significantly improves the chromatic aberration correction effect and enhances the image quality; For astrophotography it can precisely frame celestial bodies that may appear too small in the telescope's field of view
