Description

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,Ultra-wideband coating: On every glass/air surface, we use the best multi-coating to ensure maximum contrast. Crisp Image;Super Multi-coated 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; SV503 102mm are suited for those in astrophotography who want to observe binaries, compact nebulae, and star clusters. Besides, it is also suited for those to pick up more details about planets.as well as casual terrestrial,viewing wildlife, scenery; Extra-low Dispersion Glass: 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. 1.97 Arc-second Resolution The SV503 ED astronomical telescope can reach 1.97 angular seconds to let you see finer details either in astronomy or wildlife viewing. 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. 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.

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
