Alstar 1.25 inch 2X Short Barlow Lens, 3-Elements Fully Multi-Coated Optics Barlow Eyepiece with Brass Compression Ring for Astronomy Planetary Observation
Special Features
2X short Barlow lens - ultra-short, 3-element Barlow - high contrast without chromatic aberration.
Filter thread for any 1.25" filter, high-quality finish with protective dust cap.
The combination of three lens elements means the Alstar 2X short Barlow provides particularly clear and sharp images.
A built-in compression ring grips your eyepieces over a surface and not only at a point, as would be the case with unsophisticated models.
Use this Barlow where in particular where you need a shorter length.
