Rigel Aline Collimation Cap£5.40
The Rigel Aline Collimation cap offers a convenient and affordable means of collimating a Newtonian telescope.
If you simply look down the focuser drawtube, it is hard to tell where to place your eye. The Rigel Aline makes it easy to place your eye close to centre.

The Baader Laser Collimator has a precision-etched reticule featuring hundreds of tiny cross-hairs which light up brightly when the reflected laser beam touches them. Easily visible from any viewing angle. Even if the optics are off to a large degree, the reflected beam can be traced right through to the reticule and the telescope optics adjusted until the beam falls back on itself.

This artificial star provides a dependable, steady and stable reference for precise star collimation. Its very bright 18,000mcd ultra white LED focused on a 100 micron precision laser drilled stainless steel aperture produces beautiful diffraction rings when defocused in any eyepiece.
