SVBONY SV48P 2" 90500 Refractor Telescopes OTA w/ SV305 CMOS Planetary Camera

Product Description The SV48P Astronomical Telescope has outstanding optics, high-quality mechanical components. Fitted with achromatic glass for good edge-to-edge viewing, fully multi green coated lens maximize light transmission eliminating false color. The 2 inch Rotatable Double speed focuser, for smooth operation, great feel and precise adjustability. This is a good telescope provides for astrophotography visual observers or nature watchers. General Notes: Avoid exposing the telescope to sudden temperature changes, as this can result in fogging of the objective lens as moisture condenses on it. If this should happen, place the object lens close, but not too close, to a source of heat and wait for the moisture to evaporate. Caution: Never look directly at the sun with naked eye or with a telescope (unless you have the proper solar filter) Adult supervision is recommended when it is for use by children ages under 10 years old How to get started with Astrophotography? Firstly, you need choose a telescope.For beginner astronomers, a refractor is the better beginner telescope for astrophotography. Designed for Camera photography Loosen the screw that fixes the focuser on the telescope, the focuser can rotate 360 degrees.When you use the camera, you don’t need to unscrew the camera to adjust the angle.You only need to loosen the screws, adjust the camera angle, and then tighten the screws. BSI CMOS Sensor IMX290LQR The SV305 uses an extremely sensitive CMOS sensor, the Sony IMX290. This sensor has very high QE, and very low (0.7e-) read noise, which improve sensitivity in the visible-light and near infrared light regions for industrial applications. High QE The SV305 has a built-in 128MB DDRII image buffer. The benefit of the 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. This buffer also allows a slower computer with USB 2.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals. This buffer also makes it possible to run multiple cameras using one computer without USB transfer problems. 128MB DDR Buffer & USB 2.0 The SV305 has a built-in 128MB DDRII image buffer. The benefit of the 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. This buffer also allows a slower computer with USB 2.0 socket to capture every frame without loss even if the USB socket is occasionally busy with other peripherals. This buffer also makes it possible to run multiple cameras using one computer without USB transfer problems. Any Area ROI 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. ADC 12bits The SV305 camera offers 8 bit RAW output or 12 bit. The more bits you have, the subtler variations in tonal values and intensities you can hav e, and the larger values you can store. A higher bit depth provides greater dynamic range and more dynamic range is always better when it comes time to start processing your images. Pixel Size 2.9X2.9μm Smaller pixel image sensors gains more pixels inside the same camera, leading to higher resolution. IR-650 Cut The IR650 filter, high transmittance of visible light, infrared transmittance low. The human eye cannot detect the infrared part of filter, and can adjust the scenery within react to the color of the image rendering color to achieve the best visual effect, greatly improve the image quality. SV305 astronomy camera solves the general astronomy camera problem: –Optimize pixel vignetting –slow frame when planet shooting –Storage frame rate is slow –No ROI function –Short exposure time Now SV305 astronomy camera meet the basic needs of astronomy enthusiasts for planetary photography.

Some questions you may care about: Q: I can only see the green screen, I can’t get a clear image. Does the camera is defected? A : Svbony SV305 planetary camera designed with GRGB color. So when you get a green image, don’t be worried, it doesn’t means the camera is a defected one, just change/adjust the white balance, until you could get a normal image. Q: I can use the SV105 camera, and get some clear images. However, the 305 doesn’t show any image, just the dark screen. What should I do? A : The SV305 is totally different with the SV105 camera. The SV305 is designed with the SONY IMX290 sensor, it is more sensitive. And its exposure time is from 0 to 1800s, so when you first time to use it, adjust the exposure time, you could get different images. Longer exposure time, you could get more light come in. it won’t be dark screen if you toward to a bright target. Q : Can I use the SV305 planetary camera with Mac OS? A : Nope, the SV305 could not work with Mac OS now. First step, Svbony produce the Windows SDK and Driver for SV305, so you could only use the SV305 with Windows system. Thanks very much for Robin support the SV305 in sharpcap software. Second step, Svbony produce the Linux SDK and Driver for SV305 camera. You could also use your SV305 camera with Linux system now, by working with the AstroDMx software for Linux. Q: Why the Gain only shows 0 — 28.1 ? A : For the gain control, the SDK currently reports a minimum value of 10 and a maximum value of 300. SharpCap shows this instead as a range from between 1.0 to 30.0. The reason for this is that the gain value that SharpCap shows is then a meaningful number – gain 7.5 is 7.5 times brighter than minimum gain, gain 20 is 20 times brighter than minimum gain and so on. Q: Can I add filters on SV305? A :The SV305 camera contuned the style of SV105 and SV205 camera, it has standard threads M28.5*0.6 for 1.25″ filters. so you could use any Svbony 1.25″ filters to the SV305 camera. about svbony
