1. The appearance of the telescope is baked with high-end fine-grained paint, with exquisite appearance and delicate feel2. The objective lens features a S-FPL51 extra-low dispersion glass ED element, which eliminates chromatic aberration. This results in the best color correction for an ED doublet lens3. The lens adopts optical processing and low polishing technology, which is carefully carved4. The deceleration ratio of the two-speed 2\'\' toothed focusing seat is 1:10, which makes it easy to achieve accurate focus 1.This very special SV503 telescope provides astrophotographers, visual observers or nature watchers with bright, wide field views when observing starry skies or nature watching.2.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.

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 aberrationto 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. ;

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.;

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. ;

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)
