Be aware of the following as you use your Laser Collimator:

Only turn on your laser when you are going to use it. All lasers use up battery power very quickly and have short battery life.

Note the small "doughnut" or centre spot attached to your telescope's primary mirror, most have these. The doughnut is attached to help you perform alignment with the Laser Collimator.

Simple to use for fast accurate collimation
Essentially you need to first adjust the secondary mirror to get the red dot in the centre of your primary mirror, then adjust your primary mirror to return the red dot to the centre of the lasers viewing window.

  Quality item, but needs collimating  This has made such a huge difference. I used to use a Cheshire but this is much better! Now the high power (200x) views of Jupiter and Mars are much sharper on my XT8 dobsonian. However I had to collimate the laser itself which is difficult since the screws are sealed in black rubber.  (04/02/2023) Lawrence -

  Clever Stuff  Totally new to astronomy and reading about collimation was daunting. Bought this along with a Cheshire type and to be honest it really is a necessary tool. Makes things so much easier glad i got it now. Little tip pop a new battery in when you get it the one supplied is only to test it I imagine.  (13/11/2022) Steve - Snowdonia

  As expected  Ordered this device to backup a Cheshire I already own. Laser needed the obligatory collimation as expected, no big deal but worse was digging out the seals from the screw heads, but once done never need do it again. The item is sturdy & gives a feeling of confidence, a good buy & recommended.  (06/11/2022) Paul - Herts

  Laser collimator   Metal, solid and seems well made. Different brightness settings, seems ideal!  (28/03/2021) Nick west - Gosport

  Great service  Can't comment on the product, apart from the fact it appears well made, as currently waiting for my scope to be in service, hence rating. Delivery was the usual high standard from Harrisons, arriving within two days.  (22/11/2020) Andy - Peterborough

  Excellent Service  Brilliant and very useful piece of equipment, made the job so much easier. A great service an communication from the team at Harrison’s as well.  (11/05/2020) Kevin - Bristol

  excellent value for money  An excellent and useful piece of kit that should be re-used on a regular basis.  (25/04/2020) - oxford

  Very useful, and straightforward to use  I bough this along with a Newtonian reflector. The instructions aren't very clear, but it's a doddle to use. Insert it in the eyepiece holder so you can see the slanting white face while you can reach the adjustment knobs. Switch it on and twiddle the knobs until the beam disappears back down centre  (18/04/2020) Michael - Surrey

  Very pleased with the service  The item was just as described fairly quickly sent.   (07/03/2020) Daniel davies - Merthyr Tydfil

  Must have device  Does what is says on the box. I had never used one before , nor aligned a mirror on a telescope but, having read the instructions, I was able to complete the very necessary alignment within a few minutes   (03/12/2018) David - Devon

  Invaluable  beautiful accessory that is invaluable for any Newtonian telescope. Super easy to use and good quality. Fabulous service form Harrison Telescopes.   (12/10/2018) Chris Brown - Lowestoft

  Good for Dummies  Took me a while to realise that the primary mirror when correct meant that the Red Led disappeared in the centre of the collimator when aligned, Der   (15/06/2018) Ian - Birmingham, West Midlands

  Sky-Watcher Laser Collimator  By far, one of the best products for setting up my telescope I have bought to date. Can't fault it for accuracy and only took me only minutes to set up my telescope.   (17/02/2018) Chris - Penicuik, Scotland

  Excellent and time saving  I tried using a Cheshire and with glasses and a long telescope with a primary mirror i couldnt quite reach i decided to give up and get the laser. This was so much easier and allows me to quickly check the its alignment with little time wasted. I wish i bought this first time around.   (09/02/2018) Martin - Yorkshire

  Definitely a 'must have' item  This makes the job of collimating your reflector telescope as easy as 1-2-3, just slot it into the eyepiece holder and follow the instructions. I used mine to re-collimate my 8" Newtonian after taking it apart completely to carry out some modifications, and collimated it in less than 5 minutes   (23/08/2017) Martin - Barnstaple

  great service  Very quick response, and everything was as expected. Now for a starry night...   (19/05/2017) -

  excellent buy.  Took minutes to collimate my reflector the adjustable brightness levels made it easier to line up. Would recomend the this laser collimator as it is so simple to use.   (13/04/2017) michael barnett - dawlish
