Description of ๐ŸŒŒ Astromania Alignment 1.25" Next Generation Laser Collimator with 2" Adaptor for Newtonian Telescopes: Precision and Versatility Combined

Designed for Reflector telescope, with removable 2" adapter both fit for standard 1.25 inch diameter and 2 inch diameter. Red laser collimation beam with 7 brightness levels, wavelength 635-655 nm; Output power: less than 5mw, much safer for your eyes. This sturdy laser unit allows you to swiftly and precisely collimate your Newtonian telescope. Only when the optics have been accurately collimated can the telescope offer you its full performance. Built with metal material. CR2032 Lithium Cell battery (Not include) ; Accurate collimation in a few minutes provide a more clearer image. The telescope can be collimated by just one person. The precision-made aluminium housing of the laser unit has a front opening from which the laser beam can be emitted. In order to obtain an optimal adjustment, it has a side window allowing a disk oriented at 45ยฐ with a central hole to be viewed.This can be then later be used to see whether the laser is reflected back on itself, indicating well collimated optics. 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 comes fully adjusted. It can however be further adjusted if required. It has three openings for adjustment, arranged at 120ยฐ, which are initially sealed. The battery for the laser can be exchanged at any time; the small screw cap at the rear of the laser must be first unscrewed to allow this.

Flawless accuracy right out of the box

Placed in a 3D printed jig for alignment and with absolutely no measurable variation in pointer and tube positioning, from 14" to 60" from the surface and several points in between . . The alignment holes, if needed, are not under the sticker like most models I've had, but this could be accidental. No game in 2" or 1.5" configuration. good block

Pros
  • Dope ๐Ÿ”ฅ
Cons
  • No mold required

Terrible for 12 " scope

Tried for my 12" scope (f/5). Too many games! When the focuser is fully extracted, a slight movement of the collimator moves the laser beam a few centimeters to the primary side. Used it blindly and my secondary device failed. I had to do it manually through a hole in the lid. Tried this after a near perfect hand collimation, the point on the primary shifted 4 inches. The device itself appears to be collimated as the beam moves in a small circle (1 inch) as it rotates.

Pros
  • Regular price
Cons
  • New competitor

Works best in telescope accessories

2" or 1.25" collimator inserts do not quite fit in the focuser. One is a little tight, the other a little loose. Luckily I had an adapter and it was great at the time. The laser is really irreplaceable. Pointed it at the wall and adjusted the primary mirror until it disappeared, then fine tuned it but needed an adapter to get the red laser dot in the slanted collimator window right on the money. I would recommend but if it doesn't fit the focuser snugly you will need to buy an adapter (I hadโ€ฆ

  • New

MALFUNCTION AND DAMAGE to telescope and microscope accessories

UPDATE: Dealer contacted regarding issue. They sent (free to me) a NEW device that works great. The ASTROMANIA ALIGNMENT 1.25" Laser Tool was received DAMAGED. Unscrew the battery case to inspect the batteries and found: 1. The O-ring was completely torn: loose in the battery case. There was no sealing function. 2. The laser intensity dial did not connect to the smooth intensity dial, the dial either didn't move OR I was able to rotate the smooth intensity dial without moving the knurled dial.

Pros
  • Free for training purposes
Cons
  • Minor repairability

Check the collimation before you put it in the scope!

When it arrived I was very excited to collimate my Newton which arrived slightly misaligned. As a perfectionist I wanted everything to be perfect so I ordered this and got to work. This forced me to make some pretty significant changes to the collimation. I pulled out the scope and it lost focus. General. Then I jumped on the internet and found out that one should check the collimation on the collimators before touching the scope because sometimes they get very confused. Mine was *very* offโ€ฆ

Pros
  • Easy to use
Cons
  • Weak set

Arrived properly aligned. got a job

Choosing a cheap laser collimator can be confusing โ€” there are so many makes and models, and prices range from $20 to nearly $100 for what appears to be the same item (and if it actually is, probably is!). Some reviews have reported collimators failing, so being able to readjust the collimator if needed was a deal breaker. I'm happy to report that straight out of the box the Astromania was perfectly collimated but with three small plugs in case it needed adjustment (no Allen key included). Toโ€ฆ

Pros
  • Cool
Cons
  • Almost Everything Is Fine
