Description

Extra-low Dispersion glass; SV503 Telescope OTA is designed with ED glass; will give you the crystal clear image;SV503 80ED telescope produces an especially colour true and high contrast image; just right for more discerning observers Dual-speed rack and pinion focuser;The gear ratio of the dual speed 2-inch toothed focuser is 1: 10; which makes it easy to achieve accurate focus Top-quality Material; The appearance of the SV503 OTA is baked with high-end fine-grained paint; with exquisite appearance and delicate feel;all machined by CNC all optical surfaces multi-coated; The whole optical lens adopts the technology of ultra-wideband multilayer coating; 80mm aperture; fully multi-coated ED optics deliver outstanding views; day or night Areas of application; 80mm F7 astronomy telescope SV503 70/80/102ED different A thoroughly though-out design and high-quality mechanical components. This very special SV503 telescope provides astrophotographers, visual observers or nature watchers with bright, wide field views when observing starry skies or nature watching. If you are looking for a dual-purpose telescope appropriate for both terrestrial and celestial viewing, then this 102mm compact refractor is for you. This scope is ideal for terrestrial,viewing wildlife, scenery;as well as casual astronomical observation such as the Moon, star clusters and brighter deep sky objects like the Orion Nebula and Andromeda Galaxy at night. The SV503 70ED astronomical telescope can reach 1.97 angular seconds to let you see finer details either in astronomy or wildlife viewing. The SV503 80 ED astronomical telescope can reach 1.5 angular seconds to let you see finer details either in astronomy or wildlife viewing The SV503 102ED astronomical telescope can reach 1.17 angular seconds to let you see finer details either in astronomy or wildlife viewing. 70 ED 80ED 102ED 70/80/102ED identical ED(Extra-low Dispersion) S-FPL51 ED(Extra-low Dispersion) S-FPL51 is built in SV503 astronomical telescope. ED glass minimizes the effects of the secondary spectrum and reduces chromatic aberration to a remarkable degree. The high-quality 2-Element objective provides sharp and high-contrast images for travel and mobile use. Ultra-wideband Super Multi-coated Ultra-wideband super multi-coated is claimed as a remarkable seven-layer lens coating process that cuts the reflection ratio down to just 0.2% per lens surface. The result is a dramatic improvement in both color fidelity and brightness and the elimination of flare and ghost images. Dual-speed Rack and Pinion Focuser The gear ratio of the dual speed 2-inch toothed focuser is 1: 10, which makes it easy to achieve accurate focus. The dual speed focuser can provide two focusing speeds by using a set of co-axial knobs, one for fast focusing and the other for fine focusing. ; 90mm Back Focus The 90 mm back focus and 360 degree adjustable focuser are sufficient for your astrophotography needs, allowing perfect framing of your astrophotography. And the 2" RAP (rack and pinion) focuser holds more-than-5kg heavy photographic accessories safely. ; Metal Hoop with Dovetail The SV503 comes standard with adjustable tube rings and dovetail which allows it to attach to most telescope mounts. In addition, there are 1/4 inch threaded holes on the dovetail plate to attach to tripods and M6 holes on top of the tube rings to attach a guide scope.;.; Comes With a 2"-1.25" Adapter The telescope scope focuser comes with a 2 inch to 1.25 inch adapter. So that you could also use all your 1.25 inch accessories with the SV503 telescope.; CNC Machined Technology Good touch feeling and durable; 70ED Review Triangulum, Canon T3i iso1600 300s x 5, iso1600 600s x 5, iso800 900s x 5 total exp 2hrs 30min sv503 70mm iexos100 sv105/sv guidescope APT, PHD2, deep sky stacker, gimp 80ED Review James Glucksman I had a good clear night for most of last night (albeit with the addition of a pretty full moon toward midnight) so I shot these two targets--The Tarantula Nebula (narrowband) and the Ptolemy Cluster (LRGB) from here in New Zealand on my SV503 80mm.

Tips with SVbony Q: only buy the SVBONY SV503 ED telescope is enough for doing astronomy photography? A: No, this is just a beginning.Only the Telescope Tube, you can do nothing. You need to prepare some accessories for it. Then set up all the accessories with the telescope tube, then do the observation or astrophotography. Q: Only using the SV503 do Moon observation? A: I don’t recommend you start astronomy with SV503, you can start to buy a small telescope. That is enough.e.g. sv501p telescope 。 If you really want to start doing Moon observation or solar observation (you need a solar filter) with the SVBONY sv503, then here are the accessories you need. Diagonal Eyepiece Finder scope (if you want one) Mount (support the telescope & accessories’ weight) Like this: Q: I want to do some photography with the SV503 ED telescope. because many astronomers own the SV503 telescope is using it do deep space photography.i want to do this too A: Of course you can too，then you need Main photography camera Photography extension tube Dovetail for connecting finder scope (with screws) Finder scope Guiding camera (if want one) like this： Also you could connect a Nikon or Canon camera to the telescope tube. Accessories needed: Canon camera ( Of course) Camera adapter Photography extension tube Like this : about svbony
