Alpine Astronomical Baader 2x VIP Modular Barlow Lens (1.25")

Designed for flexibility and versatility, the Alpine Astronomical Baader 2x VIP Modular Barlow Lens is built with modular pieces that allow it to be easily adapted for a wide range of visual and photographic applications with the easy addition of an array of optional adapters such as diagonals, T-rings, and extension rings. A seven-layer multi-coated, apochromatic field-flattening air-spaced lens design maximizes light transmission while improving contrast and clarity and correcting spherical aberration and astigmatism.
