Remarkably high performance-per-£!
A 2x barlow fits in-between the telescope and eyepiece and doubles the eyepiece magnification.
This compact 1.25” BST StarGuider 2x barlow with fully multicoated 3-element air-spaced optics features enhanced colour correction, high contrast and excellent light transmission.
It's compact size makes it suitable for use not only with Newtonians but also telescopes fitted with a diagonal such as refractors and Schmidt-Cassegrains.
It also has 26mm clear aperture so can be used with long focal length eyepieces with minimal vignetting.
The sturdy anodised aluminium body uses an anti-marring brass compression ring and thumbscrew to grip the 1.25” eyepiece securely. The smooth-sided nosepiece is threaded to accept 1.25” astronomy filters.
