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.
- 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 DispersionGlass: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.;
SVBONY Straight-Through 8x50 illuminated finder scopes produce images that are right-side-up and left-to-right corrected views, which makes it easier to find objects in the sky. The Straight-Through Erect Image Illuminated Finder Scope, with open Center, helps you center objects precisely.
- Perfect image sharpness and good viewing comfort
- FMC Multi-coated lens surfaces
- Adjustable Brightness LED Illuminator: The deep red LED Illumination can be adjusted to just the right brightness.
- Large field of view FOV: The eyepiece has comfortable eye relief and produces a 7.3 degrees field of view.
- Focusing of lens and crosshair separately possible: Both the eyepiece and the main objective can be focused independently so that you can obtain perfect focus for your eyes.
- Power supply by 2pcs coin battery type LR754
- Viewfinder mount with 6 large adjustment screws with knurled head for easy grip; Adjusting and clamping screws have plastic tips
Wide FOV: 7.3 Degree
This finder scope has a 50mm aperture, and so provides a particularly bright image. The objects that you are not able to see with naked eyes will show in the aperture.The 7.3°FOV, 21mm long eye-relief eyepiece produces a bright 6.25mm exit pupil and will allow you to find faint galaxies, comets, and nebulae
Image Erected
The finder scope produces images that are right-side-up, left-to-right correct. In other words, things are not upside-down and backwards like most viewfinders.;
Focal Length: 185mm
The 185mm focal length finder scope is designed for use with astronomy telescopes up to 2000mm focal length. Fit perfect with Dobsonian telescopes and Schmidt-Cassegrain telescopes. Also fit perfect with our SVBONYT SV503 telescope.;
Fully Multi-coated Optics
Fully multi-coated Glass means all lens surfaces and all air-to-glass surfaces are anti-reflective multi-layer coated. The 50mm FMC lens increases the light transmission and benefits for finding targets in the night sky.;
Adjustable Brightness LED Cross-hair
The straight-through finder has a precision glass-etched illuminated reticle with cross-hair to mark the field boundaries and an open circle in the middle so that stars can be perfectly centered without being covered.The deep red illumination is continuously variable to provide the desired brightness.Compared with traditional brass cross-hair, the glass-etched reticle has a great improvement in precision and lifespan. ;
Separately Adjust the Cross-hair Angle
The angle of cross-hair is available to be adjusted separately. After aligning the finder scope, if you notice the cross-hair is at the wrong angle, then loose the knob and rotate the front part of the scope to correct the reticle instead of adjusting the whole finder scope.;
Centre the Target
The finder comes with a finder bracket, which is with 6 large adjustment screws and knurled head, easy to grip, and adjusting and clamping screws have plastic tips. After aligning your finder scope, you will find the object that in the center of your finder scope aperture shows in the center on your telescope aperture. Please note that no finder base is included. ;
Individual Focus
Both the eyepiece and the main objective can be focused independently so that you can obtain perfect focus for your eyes. ;
Power Supply: 2*LR754 Cell Battery
Applicable Dovetail Plate
（NOYE:） The mounting bracket fits standard dovetail plate from Vixen, Synta, Celestron, Skywatcher, GSO and many others 75 Degree dovetail plate.;

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.
TipswithSVbony
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)

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
