The SPIDER 230C compact radio telescope uses the WEB230-5 antenna, a mesh 2.3-meter diameter parabolic antenna designed to offer a larger diameter with lower overall weight. The 230C weighs much less than a normal 1.5 meter diameter full-surface model, offering better resolution capacity due to its greater diameter while maintaining a lower sensitivity to wind due to the perforated surface of the antenna. The reflecting surface of this antenna (the primary reflector) is composed of an aluminum mesh with 3×4 mm holes for optimum reflectivity of radio waves with frequencies up to 5 GHz.

Designed to be used with equatorial mounts

SPIDER 230C compact radio telescope is designed to be used with computerized equatorial mounts like those used by amateur astronomers with normal optical telescopes. These mounts offer, a high load capacity and pointing/tracking precision at a low price. You can use the SPIDER 230C with your equatorial mount (in order to work, the “SPIDER 230C kit without mount” requires an equatorial GOTO mount with at least 50 kg payload capacity, Losmandy-type style dovetail clamp). The mount is controlled by our RadioUniversePRO software through the ASCOM platform so if you want to use your mount, please verify that it comes with an available ASCOM driver updated for ASCOM Platform 6.

SPIDER 230C 2.3 meter diameter compact radio telescope: 1420 MHz optimised feed

H-FEED: the 1420 MHz optimized feedhorn

Developed specifically for SPIDER radio telescopes, the H-FEED feedhorn is designed for optimal illumination of the primary reflector, allowing for high gain while reducing side lobes and the spillover effect, thus obtaining the best possible performance from the 2.3 meter parabolic antenna. The feedhorn is designed to allow the reception of dual polarization with support for two professional Low Noise Amplifiers (LNA) for the 1420 MHz frequency. The feedhorn is positioned at the perfect point of focus of the antenna through a rigid structure with four supports to minimize obstruction, with a focusing device to precisely focus and maximize the performance of the entire radio telescope.

Equatorial mounts support device

Our equatorial mounts support device (patented) allows you to install the WEB230-5 antenna on any equatorial mount (with Losmandy dovetail and load capacity of at least 50 kg, ie. EQ8 type). Thanks to a two-counterweight-sliding system to protect against accidental drops, you can get a perfect balance even in the declination axis for maximum tracking and automatic goto performance of the mount. Without counterweights the radio telescope would be completely biased towards the front (because of the weight of the primary reflector and LNA + feedhorn group with support rods) and therefore could not properly point and track objects in the sky. A special system of rear tie rods increases the rigidity of the structure while minimizing the deformation of such a large diameter parabolic antenna.

SPIDER 500A MarkII 5.0 meter diameter professional radio telescope: H142-One 1420 MHz receiver for radioastronomy, radiometer and spectrometer

H142-One: the 1420 MHz receiver for radioastronomy, radiometer and spectrometer

H142-One receiver has been specially developed together with Bologna INAF Institute of Radio Astronomy specifically for SPIDER radio telescopes. H142-One provides professional technologies used by radio astronomers for radio astronomy research in a scientifically certified and easy to use receiver, perfect even with compact size antennas: it’s a 1420 MHz superheterodyne type radiometer/spectrometer, double conversion (type UP/DOWN) with 50 MHz received instantaneous bandwidth (RF=1.395MHz-1.445MHz) and 14-bit analog to digital converter. The H142-One receiver has spectrometer with 1024 channels (61 KHz spectral resolution) that are displayed and processed in real time by the control software supplied with the radio telescope. The H142-One receiver can be installed on a 19″ rack but it can also be placed on a table close to the control computer. Thanks to two dedicated IF outputs, the H142-One radio astronomy receiver allows to even improve performances by adding the optional BKND-Pro professional backend making this the perfect instrument for educational and research institutions that want to create a radio astronomy program.

RadioUniversePRO: the control, data capture and processing software for radio astronomy

SPIDER 230C comes with RadioUniversePRO  that is the most advanced software ever developed for real radio astronomy with compact radio telescopes: it gives you all the power to control the different components of your radio telescope with an immediate and easy-to-use interface. You do not have to worry about using different softwares, RadioUniversePRO is your intuitive control and data acquisition interface with the radio telescope. It allows you to control the antenna position and acquisition parameters of the receiver. This way you cannot only record data coming from the sky (deleting eventual artificial signal interferences) but also transits or radio-images of radio sources in the sky you want to study. RadioUniversePRO lets you save recorded data in graphical format as visualized on the user interface but you can also save raw data in FITS format compatible with NASA FITS Viewer, this way you can quickly open and view their data and export them to process with other softwares. System requirements are Windows 10/11 (suggested: 64 bit version), screen resolution at least 1920 x 1080, RAM memory 4 GB (suggested: 8 GB), processor i3 (suggested: i5 or i7). RadioUniversePRO is not sold separately and is supplied only with SPIDER radio telescopes.

SPIDER 230C 2.3 meter diameter compact radio telescope (kit without mount): site preparation

SPIDER 230C radio telescope is not provided with an equatorial mount (we suggest the use of a EQ8 SynScan mount, you can read how to use it in the SPIDER 230C user manual) that must be added in order to make it work. Please note that, since the mount is not weatherproof, you can’t leave the SPIDER 230C permanently installed in the field without a protection (if you want this feature, please consider the 300A and 500A radio telescopes). The image below shows cables and connections that are needed to connect antenna external unit to the control room. Power and grounding systems are needed and they have to be provided by the customer.

We perform automatic pointing and tracking on the Sun, detection and removal of eventual artificial signal and capture of results.

Radio astronomy at school with SPIDER radio telescopes

Is it possible radio astronomy at school? In general, the activities that many schools develop in astronomy are usually made ​​with optical telescopes because instruments for other electromagnetic spectrum bands are considered too expensive or difficult to use. This often translates into single evening visits with students at the public observatories, so you can not conduct a continuous study. Thanks to our SPIDER radio telescopes is now really possible to make radio astronomy at school because, unlike an optical telescope, they can also be used during the day and then during normal lesson time! The SPIDER radio telescope is installed outside and it’s remotely controlled for example from the classroom or the laboratory.
