Includes the laser collimator and the 1.25" centering adaptor at a significant saving.

Item 1 - Laser collimator: This laser collimator is primarily intended to collimate Newtonian and Dobsonian telescopes but it will also work with other reflectors like Cassegrain and Maksutov designs. A large semi-reflective display port allows the user to clearly see the return laser beam on the face of the device even in bright daylight conditions even. The port is clearly visible from the side of the collimator making is suitable for closed tube telescopes such as Imaging Newtonians. The collimator fits into the 1.25” push-fit accessory port used with medium format CCD cameras, eyepieces and webcams, which you get in the package with most telescopes. Please note that this collimator is made in Taiwan and it is a lot more accurate than other designs we've come across, performing well with Newtonians as fast as F4.0. The laser beam is lensed and produces a bright, clear dot, which is easy to see even on a newly cleaned telescope mirror. If you visit our shop, we'll be happy to demonstrate the use of this device - it's surprisingly easy to use!

Item 2 - Altair 1.25" Self-Centering Adapter: A 2" to 1.25" pushfit adapter which precisely centers any 1.25" accessory in a 2" focuser. Most 1.25" adapters use a side thumbscrew which can push a visual accessory slightly out of alignment. The Centering Adapter uses even compression from all sides which precisely centers the accessory as it is tightened in place. This adapter is especially useful with fast focal ratio reflector telescopes for precise centering of laser collimators, CCD cameras and eyepieces. It gives repeatable alignment when you swap accessories. Just leave the adapter in the telescope after collimation and swap accessories quickly and easily. Anodized aluminum with a knurled twist-lock ring, threaded for 2" filters.

Note for imagers: The upper locking ring on the self-centering adapter can be unscrewed revealing an M48 male thread, which allows you to attach various imaging accessories directly to the self-centering adapter. You need to remove the inner compression olive before connecting any camera but this can easily be put back in place before re-attaching the upper locking ring, when you need to recollimate. This means you can image without changing the collimation once everything is set up, to ensure best performance. This is particulary useful when imaging with Fast Newtonians, but also applies to and reflector telescope and refractors with tilt-adustable lens cells and fast focal ratios. The inner diameter is 31.75mm therefore this works well with most CCD cameras on the market with an equal or smaller image circle.
