NOTE: Delivery time is about 10-15 days from the order date. In fact we pre-install and test all components of

the radio telescope before delivery.

Objects that make up the Universe emit a lot of electromagnetic waves at different frequencies which are,

almost all, filtered by Earth atmosphere. However radio waves pass through unhindered and can be captured

by amateurs astronomers, too, thanks to SPIDER230. This radio telescope was developed by PrimaLuceLab

to be the first instrument for amateur radio astronomy to allow everyone to approach this fascinating science

with simplicity and an approachable cost with a single, all-in, high-performance product.

An amateur radio telescope with large 2,3 meter diameter parabolic antenna

The SPIDER230 amateur radio telescope uses the WEB230 antenna, a mesh 2.3-meter diameter parabolic

antenna designed to offer a large diameter with the lowest possible weight. It weighs much less than a normal

1.5 meters diameter full-surface model in respect to which it offers a better resolution capacity (due to greater

diameter) and a lower wind sensitivity (since the surface is perforated). The reflecting surface of this antenna

(the primary reflector) is composed of an aluminum mesh with 2x2 mm squared holes for optimum reflectivity

of radio waves with frequencies up to 12 GHz. Mesh material is positioned and installed by hand by our

technicians in order to obtain a parabolic surface as accurate as possible (within the limits of the mechanical

support). The result is a superior quality mesh parabolic antenna that offers a higher gain and a more precise

parabolic shape.

Designed to be used with equatorial mounts

The SPIDER230 amateur radio telescope is designed to use with computerized equatorial mounts already

used by amateur astronomers in normal optical telescopes. These mounts offer, a high load capacity and

pointing/tracking precision at a low price. We supply the SPIDER230 with an N-EQ6 SynScan mount but you

can install our WEB230 antenna on different equatorial mounts with at least 25 kg load capacity and

Losmandy dovetail (the same used by many telescopes) using it just like a normal telescope. For the correct

operation of the radio telescope, the equatorial mount is not installed on the tripod (which often does not have

sufficient rigidity) but on a separate column (which we provide with the SPIDER230): in this way the parabolic

antenna, while moving, never faces the impact risk against the underlying support.

Designed to work with a RadioAstroLab RAL10PL receiver

Our amateur radio telescope is designed to work with the RadioAstroLab receivers: this model is provided

with a RAL10PL Total-Power receiver working at 11.2 GHz with a Ku band feeder and high gain 4106C LNB.

RAL10PL was developed to bring amateurs to radio astronomy in order to record the most intense radio

sources in the sky and offers high sensitivity and signal stability at an affordable price.

RAL10PL is a special version designed specifically for use with the Spider230. In fact it allows the remote

control of all operating parameters that can then be set directly in RadioUniverse providing control software:

gain, offset and integration time. It also features an integratedthermal stabilizer system in order to minimize

the gain drift of the receiving system, optimizing the instrument stability.

Alignment optical finder for mounts

Computerized equatorial mounts require (for their proper functioning), to be aligned to the stars in the sky. For

this reason, we have developed a special finder bracket with a optical finder that is installed on

the counterweights shaft and that allows you to point this radio telescope to the same area of the sky "

viewed" by parabolic antenna. So, when you turn on the radio telescope for the first time and you want to align

it to the sky, you can use this finder to point the stars. In order to store the alignment you can use the mount

"parking" function: turning on the radio telescope, Spider230 will then correctly point to objects in the sky also

during the day. You can then use the finder in order to verify the correct pointing of the radio telescope during

normal use.

The finder bracket is equipped with 6 screws with knobs in order to to adjust precisely the position of

thefinder in respect with antenna. Along with this, we include a high quality and durability sunscreen glass by

Thousand Oaks. The filter is inserted in front of the finder when using the radio telescope during the day.

Equatorial mounts support device

Our equatorial mounts support device (patent pending) allows you to install the WEB230 antenna on any

equatorial mount (with Losmandy dovetail and load capacity of at least 25 kg, ie. EQ6 type). Thanks to two

counterweights sliding system with protection against accidental drops, you can get a perfect balance even in

declination axis for maximum tracking and automatic goto performances of the mount. Without counterweights

the radio telescope would be completely biased towards the front (pecause of the weight of the primary

reflector and LNB + illuminator 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 big diameter parabolic dish.

RadioUniverse control software

Included with every SPIDER230 radio telescope, our RadioUniverse software allows you to control the

antenna position and acquisition parameters of RAL10PL receiver. This way you can not only record

radiometric data coming from the sky but also transits or radio-images of radio sources in the sky you want to

study. A window shows the entire sky with the position of the main radio sources with respect to stars and

constellations.

SPIDER23 radio telescope connects to control computer via a single network cable (Ethernet). The mount

and the receiver send the data to the control electronics contained in waterproof box with the receiver. The

data is then converted and sent to the control PC via a single network cable that can be up to 100 meters.

RUviz processing software

When you want to record the faint radio waves coming from radio sources outside of the Solar System, the

data processing is critical. That's why we designed RUvizsoftware (RadioUniverseVisualizer) which allows you

to import data captured by RadioUniverse and process them in a very simple and fast way. In this way it is

possible, starting from the registration of several consecutive transits of the sky area that you want to analyze,

to create radio maps of faint radio sources such as Cassiopeia A and Taurus A.

RUviz uses special algorithms in order to to reduce the signal drift caused by the change of the antenna

pointing. Other features allow you to minimize the drifts due to variations in ambient temperature.

Reliable results

Spider230 is designed to record radio waves coming not only from strong sources such as the Sun or the

Moon, but also from more distant objects, that until now were studied only by professionals!

Thanks to its high sensitivity, it is possible to record radio waves coming from weak objects such as

Cassiopeia A (supernova remnant), Cygnus A (radio galaxy) or Taurus A (M1, supernova remnant). Thanks to

the advanced features of Spider230 and RadioUniverse software, for each object you can get different results:

radio-images, transits or continuous monitoring of a single point.

Why not use a full dish?

Full dish parabolic antennas ensure, with same diameter of a mesh model, a higher gain so, in theory, they

would be ideal choice, but they are also much heavier (a full 1.5 metre diameter aluminum parabolic antenna

weighs no less than 20 Kg, much more than primary reflector of our mesh parabolic antenna that weighs only

10 kg). So, on the same mount (eg an EQ6), you can install our WEB230 2.3 metre parabolic antenna or a full

dish smaller than 1.2 - 1.4 metres diameter. What does this mean?

1) Our parabolic antenna sain is slightly higher so it gives a better ‘sensitivity’ to whole system

2) Our dish has a greater diameter then a better resolution capability: it allows you to record finer details

3) The full parabolic dish also reflects infrared that heats LNB (so placed on the focal point) and therefore

increases electronic noise. Our mesh parabolic antenna does not reflect infrared so it does not heat the LNB.

ATTENTION: The equatorial mounts are not waterproof so you need to cover the radio telescope with a

special protective structure (which must also protect parabolic antenna from strong wind). So we developed

the SHELL 4.2 meter diameter dome that allows you to protect the radio telescope keeping it permanently

installed in the field. In this way, the instrument will always be aligned on the sky: mount can maintain both

polar and stars alignment (thanks to the parking functionality). The dome also serves to protect the radio

telescope in case of wind: when it exceeds 25 km/h, it is necessary to keep the radio telescope pointed at the

zenith (the vertical) and closed inside the dome.

The SHELL dome is opened and closed manually, it has a protective waterproof Nylon cover and, unlike

normal domes for astronomy, when you open it frees the whole sky and is therefore perfect for the radio

telescope. SHELL provides a rigid metal frame with arched supports made of aluminum, a structure anchored

to the ground with 14 metal supports and polyethylene partition wall and a system of quick coupling and

release of the dome for a quick opening or closing.
