Primary mirror collimation is the most critical adjustment in a Newtonian, and itвЂ™s been realized that with modern fast focal ratios of f/4.5 and faster, the errors which can occur in laser collimating the primary using the conventional method of folding the beam back on itself can exceed good collimation вЂ¦. 13/02/2012В В· The problem with the Baader Laser Collimator is that it's body is not symmetrical so you can't really use the "V" block method to collimate it - the instructions with them actually suggest that you return the device to the factory for collimation..
Collimation is the process of aligning the optical axes of all the optical elements in a telescope. When properly collimated, all the mirrors (or lens) will be centered and angled so that the light entering the telescope will form the sharpest possible image. The Collimation Eyepiece is a combination of a "sight tube" and a "Cheshire eyepiece." The sight tube portion of the Collimation Now you're done collimating your dobsonian or newtonian telescope, so it's time to remove the laser collimator by first switching it off, then untightening its compression ring and taking it out of the focuser. Once you've removed the laser collimator, insert in the focuser barlov and the eyepiece, and tighten them back in place.
22/01/2014В В· Interesting, in the video I attached, Robert Dalby mentions the device is intended for Newtonian telescopes (just before the first minute mark), and again, for reflecting telescopes, a bit after the 2-1/2 minute mark..

Laser collimator (not useful unless perfectly collimated itself, possessed of a small beam diameter, and not accurate enough for primary mirror collimation unless used with a Barlow lens, but quite useful in the dark. Mfrs.: Glatter,.
20/08/2008В В· Newtonian telescope laser collimation using HOTECH SCA Laser Collimator - http://www.hotechusa.com/2-SCA-Crosshair-Laser-Collimator-p/sca-2c.htm - Product ho.... A laser collimator uses the principle of auto-collimation. From the center of the focuser, it sends a beam to the diagonal, on to the primary, back to the diagonal, then back to the focuser. When collimated, the beam hits the center of both mirrors and returns directly to its source.. 2 Figure 2. Collimating the optics. (a) When the mirrors are properly aligned, the view down the focuser drawtube should look like this. (b) With the collimation cap in place, if the optics are out of alignment, the view might look something like this..
For Newtonian-style telescopes, including the Schmidt-Newtonian and Maksutov- Newtonian, this task is usually accomplished by adjusting the secondary diagonal mirror, followed by the primary mirror, using a laser collimator or other collimation aid.
