Starlight Xpress Lodestar X2

For years, the Lodestar has been held in the highest regard as being the best autoguider on the market. The innovative minds at Starlight Xpress have been trying to improve on the iconic Lodestar since it’s conception; however, this has proved to be very difficult to achieve - until now that is.

Introducing the Lodestar X2; the latest and most sensitive compact guide camera from Starlight Xpress.

Key Features:
Big things can come in small packages and the Lodestar X2, really is no exception. This compact guide camera is packed full of great features:
ONLY 1Ό” in diameter allows it to drop neatly into your 1Ό” eyepiece holder - no additional adaptors required.
Large Imaging Area (6.45mm x 4.75mm) giving you a wide field of view to find a suitable guide star.
Sensitivity - with an impressive 77% QE, and large pixels, the Lodestar X2 just sucks up those photons. Sensitivity is key, but combined with the incredibly low noise of the Lodestar X2, finding a guide star has just become even easier.
‘Full size RJ12’ Autoguider Port - No need to run extra cables from your computer to control your mount corrections.
Powered by the USB of your computer so no need to carry an extra power supply with you - one less thing to forget when you are on your way to the Star Party.

Starlight Xpress TRIUS 825 Mono and Colour CCD Camera

We are pleased to announce the two new additions to the Trius family,the Trius SX-825 and the Trius SX-825C.

A key feature of the new cameras design is the introduction of the new ICX825 ExView2 CCD from Sony (with 1.447.680 x 6.45uM pixels in a 9
x 6.7mm array.) with an amazing 77% QE and ultra-low dark current, which means that dark frames are now totally redundant, especially with the amazing -55C (below ambient) cooling.

It also means that the camera has no need of heavy cooling fins, or water-cooling pipes and mess.

With very high QE, including very high Ha QE, and ultra low noise the TRIUS 825 is one of the most sensitive camera's available to amateur astronomers and with its 6.45 micron pixels is a genuine dual purpose camera capable of taking sharp images with small refractors but equally at home when used with larger aperture much longer focal length telescopes.

With the Argon filled CCD chamber and built-in USB2.0 3-port hub, this is truly an outstanding astronomy camera.

The Trius SX-825 is available now.

Technical Specs:

Sensor Type CCD - Sony ICX825
Horizontal Resolution 1392 pixels
Vertical Resolution 1040 pixels
Pixel Size 6.45 ΅M x 6.45 ΅M
ADC 16 bit
Cooing - -50 Degrees C below Ambient
Back Focus - 17.5mm


Starlight Xpress TRIUS Range of CCD Camera's

Starlight Xpress has always been renowned for small, compact, innovative designs, along with excellent build quality.

The new Trius range of deep-sky, cooled CCD cameras has just taken these values to a whole new level.

In addition to the already super low-noise performance of the previous generations of SXV, SXVF, & SXVR cameras, the new Trius range is even better, whilst still offering fast download times of approximately 2 million pixels per second.

Remarkably, SX have also managed to incorporate a complete powered USB hub into the main camera, which offers 3 x USB 2.0 ports at the rear of the camera. Each port is capable of delivering up to 200mA, thus able to drive a Lodestar, SuperStar or CoStar for guiding leaving another two USB ports for a USB filter wheel and one other peripheral.

This integration greatly reduces the number of cable trails back to the computer and gives less potential for cables tangling around the mount during your imaging session.

New Peltier cooler combinations have been designed into the Trius cameras, along with an Argon-Filled CCD chamber, allowing a greater differential cooling delta to be achieved.

Internal Cooling
Fan Rear Camera Panel
The Trius camera provides multiple inputs and outputs. The main control connections to the camera are the USB2.0 socket that controls the
camera from the computer and the +12v DC jack socket which provides power (approximately 1.25Amps at 12v DC). In addition, there is an RJ11
Guider Port output that is opto-isolated and will drive any standard activelow guider input via the RJ11 ‘telephone’ lead provided. The remaining
sockets are three Mini-5pin USB2.0 sockets that can be used to power up to three different USB devices, such as a Lodestar Autoguider, an SX
USB Filter Wheel and a focuser. Each USB port is capable of providing 5v DC at a maximum of 200mA.

Fused Silica Window
Unlike less expensive cameras, SX fit a specially manufactured fused silica window, with a 7 layer anti-reflective coating, to all of their
Trius cameras. This offers exceptional strength and heat transfer characteristics to ensure there is less chance of dewing of the front window during humid weather.

Efficient Cooling System
The cooling system is designed for the most efficient cooling possible in a small compact package. The Trius cameras are fitted with a new peltier cooler configuration to give approximately -40C delta T. A built in fan at the rear of the camera draws air in through small holes in the front of the barrel (which increases the surface area to aid the convection), through the heatsink where all the heat is generated, and expels it out of the rear of the camera. An additional fan is fitted to the side, just to help keep the
external body at the ambient temperature during warmer weather. SetPoint Cooling as standard.

Argon Filled CCD Chamber

Argon filled CCD chambers are normally only associated with really highend cameras; the new Trius cameras have dry argon injected into the
CCD chamber to ensure there is no moisture to condense on the CCD during the cooling process. The low thermal conductivity of argon also helps with the cooling process, allowing a lower delta T to be achieved.

Unique Tilted Camera Front

This unique approach to camera design allows the front plate of the camera to be orthogonally aligned to ensure that the CCD and the optics are parallel to each other. This enables the user to adjust for any collimation issues throughout the whole optical train, to ensure pinpoint
stars across the entire field.
