Alignment 1.25" Next Generation Laser Collimator for Newtonian Telescopes - with This Laser You can collimate Your Newtonian Telescope Just in Few Minutes(Without Battery)

It works...

The laser collimator I received needed calibration before I could use it, but instrument calibration is a known routine in the measuring industry. In which case, the laser collimator is no exception. It can be a simple matter, however, of rotating the collimator in a jig until the red dot becomes stationary. Afterwards, it will help perfect the collimation of a Newtonian Reflector telescope, first aligning the secondary mirror then the primary mirror. You will need a good adapter 2" adapter so there is no play between the focuser tube and the adapter. (The extra adapter is left out with this brand collimator).If your focuser is so-equipped, you can use the laser collimator to fine tune the secondary mirror by way of the focuser collimating screws. A Cheshire collimator can double-check the primary mirror.

Perfected collimation of the primary mirror center with the secondary mirror centering and return through the focusing tube! However, the alignment of the secondary mirror with the eyepiece focusing tube must be done first, and is best done with a Cheshire Eyepiece, before performing laser collimation (alignment) of the primary/secondary/focus tube. If the secondary mirror is not properly aligned with the focus tube, this laser collimator will appear to work but in fact your image will appear slightly 'hazy' and not as crisp and crystal clear as your eyepiece optics will allow.

I have tripped on my telescope, and it fell on the grass. Nothing was broken, but the collimation was completely shot. I bought this Solomark 7 to collimate my EQ127 telescope. It has worked wonders in getting my scope up to snuff. It is still off, and Saturn looks quite blurry. This is not a problem of the Solomark Collimator. It is a problem of the impossible to collimate EQ127. This device has different level of brightness to assist in the collimation process. It is a very good device for collimating reflector type telescopes. The price is right, and the device works quite well as intended.

As soon as you put the battery in, it's on. There isn't a way to turn it off, besides taking the cap off and prying out the battery with a tool. Find another alignment tool.

I'm still working on getting my Schmidt Newtonian properly aligned and calibrated but this item definitely is making the process easier.

Easy to use when it works. The laser randomly changes brightness and needed adjustment out of the box. Once it was adjusted the beam was a bit large, but for the price I can't complain too much. When this one dies I'll buy a nicer one.

This unit will work but has a loose fit in the eyepiece holder. It is easy to use and has seven laser intensity levels.It does not come with a CR 2032 battery.

This product was priced right and worked flawlessly. Had it at max brightness as I columated during the day.

mon télescope fonctionne beaucoup mieux.

This collimator works well. Checked its collimation in a vee block and alignment was very good right out of the box. No adjustment was needed but the screws are easily accessible if necessary. The brighness adjustment goes from a very dim set at "1" in gradual steps up to "5". There is a big jump in brightness from "5" to "6" and the dot size increases somewhat. Levels "6" and "7" are bright enough to be used in saylight conditions.
