I love my Orion ED80 and didn’t want to lug it around and cause any damage to it. Enter SVBONY ED80 with FPL51 glass. My jaw dropped when I viewed the moon with a SVBONY 7-21 zoom eyepiece. There was ZERO difference between this scope and my Orion ED 80 with FPL 53 glass. I am not kidding. It amazes me to see how SVBONY can deliver such an amazing scope at this price point. I will go one step further and state that the focuser on the SVBONY is much smoother and easier to reach focus. As and added bonus, it came with the mounting rings too. This telescope amazes me and I highly recommend it to anyone who is looking for a workhorse of a telescope with excellent image quality. Don’t let anyone tell you otherwise. Get them while they are still available. I ordered a High quality Binoviewer and just can’t wait for it to arrive to pair it with this telescope for planetary and brighter DSO viewing. Clear Skies. Review: Envoi du colis Emballage irrĂ©prochable : le tube Ă©tait lovĂ© dans une mousse dense, solidement calĂ©. ExpĂ©dition rapide, suivi prĂ©cis, message d’envoi soignĂ© ; on sent une vĂ©ritable attention portĂ©e au matĂ©riel. Le carton d’extĂ©rieur, robuste, est arrivĂ© sans dĂ©chirures. QualitĂ© du produit (SVBONY SV503 70ED F6) Un bel instrument, de belle facture : anodisation soignĂ©e, pare-buĂ©e rĂ©tractable, colliers et queue d’aronde impeccables. Le focalisateur RAP, dotĂ© d’une micro-rĂ©duction prĂ©cise, offre une mise au point d’une douceur remarquable et tient fermement la position. L’optique ED dĂ©livre des Ă©toiles fines, un contraste plaisant et un chromatisme trĂšs bien contenu ; la Lune, les amas ouverts et les nĂ©buleuses gagnent en relief. En astrophotographie comme en observation visuelle, la compacitĂ© du 70ED F6 en fait un compagnon agile et fiable. En somme, un tube qui conjugue sĂ©rieux mĂ©canique et belle performance optique. ## Features - 102mm objective lens diameter and f/7 focal ratio telescope OTA; large objective lens brings more lights into the scope body and you will get more bright and clear image - Doublet air spaced achromatic S-FPL51 ED glass provides you less chromatic aberration image - Crisp Image; ultra wide band multi-layer coating technology; 102mm aperture optics and retactable lens hood deliver bright wide-field images with sharp resolution - 90mm back focus; it comes with dual focus rack and pinion focuser with focus knob cover; you can get precious focus easily - Package includes; 102mm refractor OTA; 2 inch to 1.25inch adapter;metal hoop and dovetail; objective focuser wheel cover; a package with die-cut foam insert ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08ZS66JRB | | Additional Features | 133mm Retractable Lens Hood, 360° Field Rotator, Dual-speed focusing, Fully Multi-Coated, S-FPL51 ED glass | | Age Range Description | teens adults middle-aged and elderly | | Best Sellers Rank | #1,123 in Camera & Photo Products ( See Top 100 in Camera & Photo Products ) #79 in Telescope Refractors | | Brand | SVBONY | | Built-In Media | 1 X 2" -1.25" Adapter & 1.25" Dust Cover, 1 X Dovetail Plate, 1 X Lens Cover, 1 X Pair Telescope Tube Ring, 1 X SV503 102 F7 Telescope | | Coating | Fully Multi-Coated | | Compatible Devices | Camera, Finder scope, Mirror Diagonal, Telescope Eyepiece, Telescope Filter | | Customer Reviews | 4.7 out of 5 stars 342 Reviews | | Exit Pupil Diameter | 0.5 Millimeters | | Eye Piece Lens Description | Barlow | | Field Of View | 1.45 Degrees | | Finderscope | no | | Focal Length Description | 714 millimeters | | Focus Type | Manual Focus | | Item Dimensions D x W x H | 24.77"D x 7.07"W x 8.64"H | | Item Weight | 3.95 Kilograms | | Manufacturer | SVBONY | | Manufacturer Part Number | FCAF9359D | | Model Name | FF9359D | | Model Number | FCAF9359D | | Mount | Tripod Mount | | Objective Lens Diameter | 102 Millimeters | | Optical Tube Length | 630 Millimeters | | Optical-Tube Length | 630 Millimeters | | Power Source | Adapter | | Telescope Mount Description | Tripod Mount | | Warranty Description | We provide lifetime warranty for telescope or OTA and 30 days no reason to return.
