The shipment of the laser was, as with my other products by Seben, quickly and easily. In contrast to the product of the laser was not adjusted. Perpendicular in focuser my 900mm Newton-he generated when rotated through 360 ° in a circle on the main level a considerably larger 2 coin. At a Haupspiegeljustage is not to think. The adjustment of the laser is but done in a few minutes and then everything works perfectly. 3 stars I forgive, because 1. the laser was delivered not well adjusted, the adjustment screws are 2 filled with silicone (which must be removed before adjustment) and 3. the adjustment screws are easily accessible (it is without re-fix with silicone, adjustment not hold permanently)
