Small pits are occasionally visible due to processing in the polishing and figuring process, these again cannot be accepted as reason for complaint. If there are a few sleeks or scratches on the optics surface they in no way effect the performance of the lens or mirror either visually or photographically and cannot be considered as an acceptable reason for any complaint. The surfaces of mirrors - Information from Orion UKManufacturing precision optical surfaces, (in this category we include both mirrors and corrector lenses), involves many specialised procedures to achieve the high degree of optical precision, some of which occasionally leave surface blemishes on the optic (mirror and/or lens). Astrophotography is not excluded and an option for the future. We recommend this telescope to all amateur astronomers who want a powerful telescope for mobile use with a focus on visual observation. DSLR cameras up to APS-C sensors do not even need a coma corrector, like CCD cameras with sensors up to approx. Of course, astrophotography is possible, too. Stars are sharp to the edge of the field of the eyepiece. The Newtonian coma, a problem of fast Newtonians, is not an issue with this telescope, due to the moderate focal ratio. Due to its secondary mirror with only 50 mm diameter (25% obstruction), the Newtonian offers excellent sharpness and high contrast at moon and planets. It can be carried by mounts like the Skywatcher EQ5 or the Celestron Advanced VX. The Orion VX8L Newtonian:With 8 kg weight, the telescope is well portable. ♦ Each VX Newtonian comes with a computer optimised 9-point cell for the primary ♦ The new 2" Crayford focuser also offers better stability, now allowing astrophotography ♦ The aluminium tube is thicker and more stable, so collimation is well kept ♦ Primary and secondary mirrors have HILUX coating with 97% reflectivity for a bright and crisp image ♦ Each telescope is supplied with an interferometer report - you can see how good your optics is The mirror substrate comes from SCHOTT and the telescopes are made in England.Īdvantages and features of the Orion UK VX Newtonian telescopes: The excellent optical quality has remained the same. Orion Optics VX Newtonian TelescopesThe new VX telescope line from Orion UK has been completely revised, now offering many advantages for obervation and astrophotography.
