SV503 70ED:Multi-function OTA suitable for shooting sun and moon, landscape scenery, deep space photographySV305 Pro camera is a sensitive and high-speed color astronomy camera for planetary imaging, lunar and solar imaging (with a safe solar filter), and some bright deep space objects imaging. This camera is also great for ‘lucky imaging’of planets, double stars, and other compact objects, especially for telescopes with longer focal lengths.
Multi-function OTA: suitable for shooting sun and moon, landscape scenery, deep space photography (works better with 1/2 or 1/3 inch sensor, the pixel size in 3μm-5μm, and need to match the SV193(not included).
- The SV503 comes standard with adjustable tube rings and dovetail which allows it to attach to most telescope mounts.In addition, there are1/4inch and3/8 inch threaded holes on the dovetail plat to attach to heavy duty tripodsandM6 holes ontop of the tube ringsto attach a guidescope.
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. ;
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.;
CNC Machined Technology
Good touch feeling and durable;
SV305 Pro camera is a sensitive and high-speed color astronomy camera for planetary imaging, lunar and solar imaging (with a safe solar filter), and some bright deep space objects imaging. This camera is also great for ‘lucky imaging’of planets, double stars, and other compact objects, especially for telescopes with longer focal lengths.
128MB DDR Buffer
The benefit of the built-in 128MB DDRII image buffer is that the memory will cache the image and transfer it to the computer when the USB interface is not busy or being interrupted, and the frame will not be lost or corrupted.
Back-illuminated (BSI) CMOS Sensor
The SV305 Pro uses an extremely sensitive CMOS sensor, the Sony IMX290.This sensor has very high QE, and very low (0.7e-) read noise, which improves sensitivity in the visible-light and near infrared light regions for industrial applications.
ST4 Guiding
The camera designed with ST4 guiding port, supports the PHD2 software, and works with ASCOM plate form. You can use the computer to control it, and telescope mounts have an autoguiding port that connects directly to the autoguider (usually referred to as an ST-4 port, which works with analog signals).
Any Area ROI Support
The SV305 Pro has ROI function. A smaller region of interest (ROI) is read out from the sensor, leaving the image scale of the object being imaged, unchanged. Allow arbitrary resolutions to be set.
USB3.0 High Speed Transmission
USB3.0 high speed data transmission is quick and efficient for planetary, lunar and solar imaging.
ADC 12bit
The SV305 Pro camera offers 8 bit RAW output or 12 bit.
Special Heat Dissipation Structure
The unique heat dissipation design makes the product run more stably. Long-term exposure during use reduces the noise to a certain extent and makes the image quality better.
NOTE:
Computer configuration requirements:
1)The configuration of desktop computer is not less than Intel 4 generation i5, and the memory is not less than 4G.
2)Laptop configuration is not less than Intel 6 generation i5, memory is not less than 8g.
2. This SV305 Pro camera is best used with a refractor or reflector telescope mounted on an equatorial mount that can accurately track the motion of the sky. It is not intended for taking images through the eyepiece of a telescope. You may also require additional accessories and filters to get the best results. If you want to use the SV305 pro camera capture images through telescope eyepiece. you need buy an eyepiece projection adapter.
All software and drivers for this camera are available from the manufacturer’s website.
Some questions you may care about:The difference between F9198Band F9198C:The window glass is changed from the original IR650 to AR anti-reflection coated glass, which can be used with IR CUT filters to capture visible light, and with IR685, IR850 and other filters for infrared light shooting.What software supports the SV305 pro camera ?

How is SV305 Pro camera?
Here are the testing results from Dr. Steve Wainwright. ( He has been an astronomer since 1967. He taught astronomy at the University of Swansea in D.A.C.E. evening classes for several years, but now, largely retired. For several years he has been working with his partner Nicola on AstroDMx Capture. They do great help for Svbony cameras working with Linux system. Many thanks for Steve and Nicola.)

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
