If you have a Newtonian Reflector Telescope, one of the most frequently noted disadvantages is its need for regular collimation, or known as alignment.
Saxon Laser Collimator is specially designed to reduce this painful work into a minor task. Powered by one CR2032 lithium battery (included), this aluminium Laser Collimator has a bulls-eye target to let you adjust the telescope's primary mirror easily by tweaking the adjustment screws, the collimation process is successful once the laser beam hits the bulls-eye.
Promising precise alignment of your telescope, collimate your telescope with the Saxon Laser Collimator today!
Hmmmm ok, for the price I expect instructions.
Anyway Youtube is your friend for how to use the Laser collimator.
Once I found a video on YT I collimated the scope, it was off the centre mark of the primary mirror by 20mm, not good considering Sky Watcher Dobs are meant to be factory collimated, mine was out.
PRO's - Took me about 10 mins all up and is a great easy way to collimate your scope. Shipping was two day to Darwin, thats great.
CON's - Exensive considering it comes in a blank box, has no branding on it and has no instructions.

Pros: light, portability, user friendly, accurate, quality +++
The beam adjustment knob is nice to use, has a good "feel" about it, no "sloppiness", and it has a range of beam sizes to choose from.
It also has an easy to see target for the return beam.
Coming with the 2" adapter means this is the only collimator you would ever need. Oh, the adapter is metal too. (Posted on Feb 12, 2011)
