## Overview

The Astromania Alignment 1.25" Next Generation Laser Collimator is a precision tool designed for quick and accurate collimation of Newtonian telescopes. Featuring a red laser with 7 adjustable brightness levels, premium anodized aluminum construction, and compatibility with all standard 1.25" focusers, it enables both amateur and professional astronomers to achieve optimal mirror alignment in minutes. Factory-calibrated and easily adjustable, this collimator ensures your telescope delivers its sharpest, clearest images every time.

## Description

Product Description 1.25" Next Generation Laser Collimator -Newtonian reflectors perform at their best when primary and secondary mirrors are accurately aligned. Such alignment, called collimation, is critical for achieving a sharp, highly resolved view through the telescope. -The Laser Collimator, designed specifically for collimating the optics of Newtonian reflectors, provides a quick, easy way to a) determine if one or both of your telescope’s mirrors need adjustment, and b) make the necessary adjustment(s) quickly and easily. -It uses a low wattage laser to project a red beam down through the telescope’s focuser. The beam reflects off the secondary mirror to the primary mirror, then bounces back up to the secondary mirror and exits through the focuser onto the angled, bulls-eye viewing screen of the collimator itself. The beam is generally not visible, but you‘ll see a bright red dot on each reflected surface. The Laser Collimator works equally well to collimate telescope optics in daylight or at night in the dark, and has been precisely aligned within its housing at the factory. Installing Battery The Laser Collimator is powered by one CR2032 battery (Not Included). When the laser beam starts to dim or completely fades, it’s time to replace the battery. To do so, unscrew the knurled battery compartment cap at the top of the collimator. With a knife tip or the end of a paper clip, lift the edge of the expired battery out. Insert a fresh CR2032 battery with the positive (+) side up. Then replace the cap. The CR2032 is a commonly used battery in watches, calculators, cameras, and other electronic devices, so you’ll be able to find one at most drug/hardware stores or online. Care and Maintenance Your Laser Collimator is manufactured of the highest quality components. The internal laser diode is precision aligned with the mechanical axis of the housing at the factory and tested to meet stringent specifications. Like all electronic equipment, the Laser Collimator should be handled with care. If it is dropped or handled roughly, the internal laser could become misaligned. Avoid exposing the collimator to water, dust, heat. To extend battery life, store the collimator in a cool, dry environment. Dual Language Instruction This adjustment tool can be used in all 1.25" focusers. We provide you with precise instructions in German and English, with a step-by-step explanation of how to adjust a Newtonian telescope using this laser unit. So, even if you are a newcomer to amateur astronomy, it is very simple to get the optimum performance out of your telescope. Recalibrating the Laser Collimator The Laser Collimator has been precisely aligned at the factory and can be used directly, unless a strong impact which require recalibration. You need a holder that is required is a suitable "V" block to rest the collimator body in so that it can be rotated through 360 degrees. To check the calibration, the laser should be rested in the jig aimed at a wall about 6 metres (20 ft) away and slowly rotated. If the laser dot on the wall describes a circle, then the collimator is out of calibration. There are three adjustable screws around the body of the unit (Please refer to the picture) and by loosening one and tightening another, it will be seen that the laser dot will move slightly. Only minute adjustments should be made and the screws should not be over-tightened or made too loose. What you are aiming for is a full rotation of the collimator in the jig resulting in NO movement of the laser dot on the far wall.

Review: Accurate collimeter. - Received this yesterday - poorly packed however and it was rattling around in a box - as it came from a US supplier I expected the worst when I opened it. However - it seemed to be physically OK. Inserted a CR2032 battery without any issues whatsoever and it powered up. Upon checking the accuracy of the collimination in a home made jig, I found it to be spot on and it required no adjustments. So I have given it a 5 star rating.

## Features

- Multi-Function: Designed for Reflector telescope; fit for standard 1.25 inch diameter; this sturdy laser unit allows to swiftly and precisely collimate Newtonian telescope; accurate collimation in a few minutes provide more clearer image
- Premium metal construction and anodizing aluminium processfor long time use; require one CR2032 lithium battery 【Battery is not Included】
- Practical Design: Red laser collimation beam with 7 brightness levels; wavelength 635-655 nm; output power: less than 5mw; much safer for your eyes; only when the optics have been accurately collimated can the telescope offer you its full performance
- Well-Engineered: The laser comes fully adjusted however further adjust if required; it has three openings for adjustment; arranged at 120°; which are initially sealed; small screw cap at the rear of the laser must be first unscrewed to allow this
- Friendly to Everyone: This adjustment tool can be used in all 1.25 inch focusers; provide with precise instructions in German and English about how to adjust Newtonian telescope using this laser unit; simple to get optimum performance out of telescope

## Questions & Answers

**Q: What size battery does this use?? The cr2032 does not appear to fit properly.**
A: It takes a CR2032, but it looks like it takes a smaller size when you're looking at it. I've never seen a battery holder like this one (though there's nothing wrong with it) The battery holder has "claws" to grab the side of the cell and an O-ring to pull the claws together and have some pressure on the connection. Just insert the battery edge into the opening and slowly press it down all around until it seats, then screw the battery cover back on. You don't need tools but there is a slot in the cover for a coin if you have trouble opening it. You'll have to hold the brightness selector ring (it has numbers on it) in place while you unscrew the battery cover (or when screwing it back on) whether you do it by hand or with a coin. This should make for better electrical contact with the battery but it might make it more difficult to remove it. Perhaps they were thinking that you might be doing this in the dark and this would keep the battery from falling out until you were ready to pull it out but if you're using a laser collimator you're not likely to be doing this in the dark anyway. When you use a star to check the final results you won't need to have this along.

**Q: Can any one provide an explaination on how to put in the battery? without forcing it i cant see how nor do i see release screws?**
A: I had to force mine.  I consider it a design flaw. Good Luck

**Q: Can i use this my orion xt6 dobsonian?**
A: definitely, it is made just for newtonians.

**Q: My unit came uncollimated and i do not know what tool can i use to move those 3 screws on a side. they are filled with pitch. what tool can i use?**
A: Just remove the "pitch" with a small blade screwdriver and a pick. The screws can be accessed.
