- 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.
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.;

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.
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.
Finder scope (if you want one)
Mount (support the telescope & accessories’ weight)
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)
Guiding camera (if want one)
Also you could connect a Nikon or Canon camera to the telescope tube.
Canon camera ( Of course)
