Designed for Reflector telescope; with removable 2" adapter both fit for standard 1.25 inch diameter and 2 inch diameter; Red laser collimation beam with 7 brightness levels; wavelength 635-655 nm; Output power: 3.8mw complies with Class 3R laser safety standards; much safer for your eyes. This sturdy laser unit allows you to swiftly and precisely collimate your Newtonian telescope; Only when the optics have been accurately collimated can the telescope offer you its full performance
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
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; The battery for the laser can be exchanged at any time; the small screw cap at the rear of the laser must be first unscrewed to allow this
It fits all rear cells of Schmidt Cassegrain telescopes and includes an adapter to use with refractor telescopes; The 2 inch SCT diagonal features dielectric coatings with 93% percent reflectivity across the visible spectrum and a 1/10 wave mirror for bright and true images
Allows you to take advantage of the wider field of view provided by two inch eyepieces; Dielectric coatings are more durable than regular or enhanced aluminum coatings so you will enjoy years of excellent performance from this product
