New 'Trius PRO' camera range

We have redesigned the main board of our Trius cameras and improved both the read noise and download times. The new range has been named 'Trius PRO' and is now available for purchase. In addition, a new Trius PRO camera has been added to the range. This is the PRO-834, which uses a Sony ICX834 CCD with 12 megapixels. This very high resolution chip has 3.1 micron square pixels and is very well matched to the short focus, fast optics, of many modern telescopes. PRO-834


New 'Full Frame' format SX-46 and SX-56 cameras

We have developed two new 'Full Frame' format cameras that incorporate the large area ON Semiconductors KAF16200 and KAF16803 CCD chips. As these devices require the use of an optical shutter, we developed a stepper motor driven 'roller blind' assembly, which provides very uniform illumination, even for very short exposure times. This simplifies the recording of flat field frames and eliminates shutter induced gradients in your images. These cameras also incorporate 'Field flood' LEDs to eliminate RBI effects and a multicoated synthetic sapphire input window to eliminate dewing. The extremely high thermal conductivity of the sapphire keeps the window warm by conduction, without the use of window heaters. The cooling is by a 3 stage Peltier and achieves better than -45C below ambient. Both cameras are housed in a 136mm square machined chamber and weigh only 1.7Kg. The input adaptor has a 72mm x 1mm female thread and the camera BFL is 16mm.

The SX-46 has 16.5M, 6uM square pixels in a 27 x 21.6mm format. The SX-56 has 16.7M, 9uM square pixels in a 36.8mm square format.

The new SX 'Maxi wheel' with 9 x 2 inch filter carousel and OAG!

SX launch a new large format filter wheel, primarily intended for use with the SX-35 and 36, but also suitable for smaller chip cameras where 5 filter positions is not sufficient. The standard carousel holds 9 unmounted 2 inch filters, but other options will be available, including 7 x 2 inch square, 11 x 36mm and 11 x 1.25" threaded.

The standard input and output adaptors are M72 x 1 mm (male and female), but 68 x 1 mm is also available. A 'Universal' adaptor is also an option. This adaptor allows any of our standard wheel rings to be used with the Maxi wheel, so that, for example, a T2 thread camera can be attached.

Oculus goes WiFi with the 'OcuPi' module!

The 'OcuPi' unit creates a Wi-Fi hotspot for your Oculus and records your night sky images to an internal SD card. Based on the 'Raspberry Pi' and with software from David Schmenk, this unit can be mounted on your Oculus mast and will send live images to an iPad. Only 12v DC is required to operate the Oculus and OcuPi units. The software will automatically start imaging at dusk and stop at dawn. It will also auto-create an mpeg movie of the previous night's frames. You can download the user manual from this link Ocupi Handbook

SX goes spectrographic!

Our compact reflective grating spectrograph is ready for launch and will be available by September. This small unit packs a high performance flat-field concave grating into a module of only 136 x 120 x 75mm and 1.2kg weight. It also includes a built-in Lodestar X2 guide camera and an argon-neon calibration lamp. The input and output are T2 thread and it is compatible with most T2 thread input imaging cameras. We recommend our SX-694 as a good match. The spectral length is 340 - 900nM over a distance of 31mm and the resolution factor is in excess of 2000. An overview by Maurice Gavin is available at



The 'Ultrastar' and 'Ultrastar C' high resolution 'Live viewing' and guide cameras. These are new 'Lodestar X2' format cameras that use the latest Sony ICX825 CCD with excellent QE and sensitivity. This CCD offers 1392 x 1040 6.45uM square pixels in an 8.9 x 6.7 mm format and is compatible a wide range of imaging / guiding software, including Paul Shears' 'Starlight Live'. Both mono and single-shot colour versions are available. 'Starlight Live version 2.0' is now available on the Ultrastar page.

The Colour Lodestar X2 is now available. With the same high performance CCD and guider socket as the standard X2, but with added colour!

The Lodestar X2 is here! The World's favourite autoguider is now even better! With its new Sony ICX829 Exview2 CCD, it offers twice the sensitivity of the original Lodestar, making guide stars even easier to find. In addition, the autoguider output socket is now a standard RJ12 connector and so overcomes any objections to the strength of the original Lodestar cable.

New 'Trius' versions of the H35 and H36 cameras are now available. The H36 now uses the Truesense KAI16070 chip with improved read noise and QE. More details to follow.

New 'Combo' packs at a discounted price. We are offering combination packs of either Trius H9, 674, 694 or 814 cameras with a 'mini' filter wheel and a Lodestar guider, at a discounted price. The mini wheel is effectively free! Please contact our dealers for pricing.

New 'Trius' camera series launch

Hot product 2   We have now released our latest series of high performance cooled cameras - the 'Trius' range. These cameras replace the previous 'SXVR' versions and add extra features to this popular design. The major change is the replacement of the 18 way port with three independent USB ports, via an internal hub chip. These sockets are intended to connect accessories, such as the SX Lodestar or filter wheel, directly through the camera and to bypass the multiple USB cables that were previously required. The Trius cameras are provided with three short 'mini B' to female 'A' leads to interface with standard USB leads and a short mini B to mini B lead for direct connection to a Lodestar, Superstar or Costar guider. 

Other major changes include a low-noise linear cooling regulator with two-stage high efficiency Peltier cooler and a dry Argon filled CCD chamber for better thermal characteristics. Please visit our products pages for more details.


New product release - Mini wheel with guider port

Hot product 2   We are pleased to announce a new 5 position 'mini filter wheel' with integrated guider port. The mini wheel is only 150mm in diameter and can accept carousels with 1.25" threaded filters or 36mm unmounted filters. Front and back T2 thread adaptors are standard.
