Description: Great scope, has no issues, the attached images were taken with it! I use my other scopes 99% of the time, this is a great scope for wide field! I am including the Laser Collimator as well. Clear Skies! The Quattro imaging Newtonian is an affordable, large aperture astrograph, ideal for users searching for a fast-imaging system that will work for both astrophotography and visual astronomy. Boasting a swift f/4 focal ratio, this astrograph can produce an exposure 6x faster than the average 8-inch f/10 Schmidt Cassegrain telescope (or 8.4x faster with the included coma corrector/reducer). Although designed as an imaging optical tube, these Newtonians also produce bright and detailed viewing for visual astronomy.Like all Sky-Watcher reflectors, the Quattro Imaging Newtonian features borosilicate mirrors coated with Sky-Watcher’s proprietary Radiant ™ Aluminum Quartz (RAQ™) coatings, producing 94% reflectivity. The tube is constructed with rolled steel, then coated with Sky-Watcher’s signature glossy metal-flake Black Diamond finish. The OTA uses an oversized secondary mirror providing greater illumination for DSLRs and CCDs using full-frame sensors, and an included coma corrector/reducer for those who want to take their imaging to the next level.Included with the Quattro Newtonian is a 11:1 dual-speed 2-inch Crayford-style focuser, 1.25 and 2-inch eyepiece adapters, a 6x30 finderscope, tube rings, V-style dovetail plate, a 70° Ultra Wide 22mm eyepiece, and coma corrector/reducer.SKUS11205UPC050234112055Optical InfoOptical DesignNewtonianMirror CoatingsProtected Aluminum coatings with 94% reflectivityGlass TypeBorosilicatePrimary Aperture (mm)150mmF/Ratio3.9Focal Length (mm)600Secondary Diameter64mmSecondary Obstruction (by diameter)42%Secondary Obstruction by Area18%Observational InfoDawes Limit0.77Rayleigh Limit0.93Limiting Mag.13.36Minimum Magnification21xMaximum Magnification295xLight Gathering (compared to next size down)40% (compared to 5" telescope)General InfoFocuser2" Dual Speed CrayfordOTA Length (Retract/Ext.)22"OTA Outer Diameter7.25"OTA Weight (with accessories)12.6 poundsAccessoriesIncluded Finder6x30 FinderIncluded DiagonalNoMounting AccessoriesMounting Rings/DovetailIncluded Eyepieces22mm 70 degree 1.25"Included CaseNoCorrectorYes
