The laser comes fully adjusted. It can however be further adjusted if required. It has three openings for adjustment, arranged at 120°, which are initially sealed.

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 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 45° 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. 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. Designed for Reflector telescope, with removable 2" adapter both fit for standard 1.25 inch diameter and 2 inch diameter.

NO ! NO ! NO ! - Accessory

I doubt this is an isolated case. After the battery is installed and I turn on the handle the laser does NOT stay on and you have to touch and move the handle to make it stay on. There was a bad connection somewhere in the laser but it was NOT there , where the battery compartment was. I say so you don't have to waste time sending it back after you get a little upset, just spend a few bucks more on a reliable brand name laser peace to all
