Only when the optics have been accurately collimated can the telescope offer you its full performance. It designed specifically for collimating the optics of Newtonian reflectors. It has a side window that allows viewing of a 45° disk with a center hole. This canbe used later to see if the laser is reflected back toitself. Red laser collimation beam with 7 brightness levels,wavelength 635-655nm; Output power: 3.8mW, much safer for your eyes. If it can be further adjusted if required, it has three openings holes for aligning adjustment . Unscrew the rear cover with your barehands, although it is designed with anti-slip knurling. You can use your belongings to open it. The Laser Collimator is powered by one ). 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 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. 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. 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. ## 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 Included】 - Practical Design: Red laser collimation beam with 7 brightness levels; wavelength 635-655 nm; Output power: 3.8mW complies with Class 3R laser safety standards; 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 ## Technical Specifications | Specification | Value | |---------------|-------| | Additional Features | 7 brightness levels red laser beam, Designed for calibrating reflecting telescopes, Solid metal body, Triple cemented of Lens | | Asin | B01D8HMBCQ | | Best Sellers Rank | #11 in Telescope Photo Adapters | | Brand | Astromania | | Coating | Ultra-High Transmission Coated | | Compatible Devices | Reflective telescopes with a 1.25 inch focuser | | Customer Reviews | 4.6 4.6 out of 5 stars (848) 4.6 out of 5 stars | | Exit Pupil Diameter | 1.25 Inches | | Eye Piece Lens Description | Plossl | | Field Of View | 1.5 Degrees | | Finderscope | Reflex | | Focal Length Description | 1.25 inches | | Focus Type | Manual Focus | | Item Dimensions D X W X H | 5.04"D x 1.28"W x 1.28"H | | Item Weight | 3 Ounces | | Manufacturer | Astromania | | Manufacturer Part Number | SKU_AM_ZAA1025 | | Model Name | Alignment 1.25" Next Generation Laser Collimator for Newtonian Telescopes - with This Laser You can collimate Your Newtonian Telescope Just in Few Minutes（With Battery） | | Model Number | 10251 | | Mount | 1.25 inches mount | | Optical Tube Length | 1.25 Inches | | Power Source | Battery Powered | | Zoom Ratio | 1:1 | ## Product Details - **Brand:** Astromania - **Eye Piece Lens Description:** Plossl - **Finderscope:** Reflex - **Focus Type:** Manual Focus - **Item Weight:** 3 Ounces - **Optical Tube Length:** 1.25 Inches - **Power Source:** Battery Powered - **Product Dimensions:** 5.04"D x 1.28"W x 1.28"H - **Telescope Mount Description:** 1.25 inches mount ## Images ![Astromania Alignment 1.25" Next Generation Laser Collimator - Image 1](https://m.media-amazon.com/images/I/712n1MN0cQL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Surprisingly Good for the Price *by on Reviewed in the United States November 26, 2024* I wasn’t expecting much given the low price, but this Astromania Laser Collimator really impressed me. It does exactly what it’s supposed to do and gets the job done without costing a fortune.What I Liked:Super Easy to Use: Setting it up was a breeze. Some reviewers mentioned issues with the battery, but I had no problems. It takes a CR2032 battery, and I had it installed in seconds—super simple.Does the Job Well: After using this collimator, my reflector telescope was perfectly aligned.

I was pleasantly surprised when I installed the (supplied) battery, turned it on and tested it in my homemade collomation device. I must got one that someone knew what they were doing because it was dead on. I put it in my reflector telescope, aligned my secondary then the primary mirrors and went outside. I located the brightest star I could see (Arcturas) and performed a star test and my scope was just about dead on and only minor primary mirror was required to get it spot on. ### ⭐⭐⭐⭐ Pretty Good *by on Reviewed in the United States July 16, 2022* This was my first collimator, and to be completely honest it was alright.Yes, it doesn't come with a battery but they're really easy to get anyways. Plus, if you have the ability of basic reading you'll realize that it says it doesn't come with a battery.The laser itself came collimated, thankfully, even though the shipping took a while, so I'd say it's sturdy. Additionally, The laser was very bright and and not blurry at all.The reason I didn't give this 5 stars was because of how horribly sticky and jammed the sockets were, and also because of the packaging itself (cardboard that disintegrated immediately).Other than that, I'd say this thing is pretty good at its job. It collimated my Dob very easily and it's pretty neat. :D9/10 ## Frequently Bought Together - Astromania Alignment 1.25" Next Generation Laser Collimator for Newtonian Telescopes - with This Laser You can collimate Your Newtonian Telescope in just a Few Minutes! - Celestron 93326 Omni Barlow Lens, Silver, 2 x 1.25 Inch - Celestron 94119-A 1.25 inch Moon Filter - Suitable for Lunar Observation, Extra Bright Planets or Terrestrial Viewing Over Sand or Snow, Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/27340155-astromania-alignment-1-25-next-generation-laser-collimator](https://www.desertcart.hk/products/27340155-astromania-alignment-1-25-next-generation-laser-collimator) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-14*
