Product Description SV503 80ED For those who want to enjoy outdoor activities in the garden,you deserve to have SV503 80ED telescope. SV503 80ED telescope’s objective lens features an S FPL-51 extra-low dispersion glass ED element, which virtually eliminates chromatic aberration. This results in the great color correction for an ED doublet lens. 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.

This very special SV503 telescope provides astrophotographers, visual observers or nature watchers with bright, wide field views when observing starry skies or nature watching. SV503 80mm are suited for those in astrophotography who need something with a wider field of view, wanting to view the sun (be sure to use an approved solar filter) and the moon. Besides, you can also see star clusters, nebula and some larger, brighter galaxies. 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. 70mm Back Focus The 70 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. 1.5 Arc-second Resolution The SV503 ED astronomical telescope can reach 1.5 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.; Review with SVbony Jean-Sebastien Gaudet Taken with Sv503 80ED/ SvBONY field flattener/ ASI294MC-pro at -10degC/ Optolong L-extreme/ 50mm guidescope/ SV305 guide camera/ Celestron ASGT 10x600s lights/ 10 darks/ 15 flats Bill Collins Copernicus Crater.

Edited with Windows Photos. 10/1/21 Stellar Haven Observatory 2021© B.R.Collins 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
