Product Details

  • A dynamite combination of the TRIUS PRO-834 Blue edition monochrome camera with Lodestar PRO autoguider and MIDI USB Filter Wheel will leave you with the most sophisticated astro-imaging set-up on the market!


    The TRIUS Pro Cameras innovate like no other, boasting impressive cooling systems and advanced electrical designs to compete with the best cameras in its class! 

    Versatile Camera Body

    All Trius Cameras have incorporated a 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 and is able to drive a Lodestar, or UltraStar for guiding and another two USB ports for our USB filter wheels, etc. This integration greatly reduces the number of cable trails back to the computer and gives less potential cable tangling around the mount during your imaging session.

    Image note: This is a Blue Edition camera, the black version is shown for demonstration purposes only.

    Low Temp Cooling Systems

    The TRIUS Pro Camera Series reach anywhere between -40 and -50 degrees of cooling, ensuring that your noise levels stay extremely low. Combined with this, each camera is designed with Argon-filled sensor chambers to further optimize this process.

    Starlight Xpress MIDI USB Filter Wheel

    The MIDI filter wheel with off-axis guide prism, is a compact solution for mobile setups, or where the lightest possible wheel and guider are required. The wheel is USB controlled and powered, with 7 filter positions for 1.25-inch filters, and a slimline OAG which is pre-set to be close to par-focal with most SX cameras. (The Lodestar X2 or UltraStar guide cameras are an ideal match to the OAG pick-off tube.) 

    The MIDI Carousel

    This carousel holds:   7 x 1.25-inch round filters. Unmounted filters may be up to 5 mm thick.

    Input and output adapters

    The standard output adaptor ring is a male T-thread (M42 x 0.75 mm) threaded version, intended for coupling to an TRIUS PRO series camera such as the PRO-694 or PRO-814. On the input side (telescope) there is a female T-thread (M42 x 0.75 mm) adapter and an alternative female 48 mm is also supplied with the MIDI filter wheel. (Other alternative adapter are also available.)

    USB Control and Power

    The MIDI filter wheel uses the same control protocol as the smaller SX wheel and has both USB and serial inputs. The entire electronic assembly is USB powered and does not need an external power supply. (the serial input does require a small PP3 style battery, if this is used). 

    Overall dimensions: Diameter: 190 mm (7.5 inches) Thickness between input and output adapters: 37 mm (1.46 inches) Weight: 0.8 kg (2 pounds)

    Lodestar PRO

    Starlight Xpress's Lodestar PRO Autoguider Camera now takes first place in the race for the Best Autoguider on the market! Finding a faint guide star is now so easy with faster download time and super low read noise figures.

    The high sensitivity and low read noise are attributed to the Sony ICX829AL CCD chip, which was also used in the Lodestar and Lodestar X2. Although the Lodestar PRO is not cooled, the low dark signal and low readout noise are able to compensate for this to guide on stars that are beyond the reach of webcams and CMOS chip based guide cameras. The UltraStar PRO is equipped with a full-size RJ12 autoguider port, so you're not forced to run extra cables from your computer to make corrections to your mount.

    The Lodestar PRO is extremely compact in size (31.75mm dia x 85mm long), which is also the size of a 1.25 inch eyepiece push fit. Bring this autoguider with you on your next star party to find your guide star and start viewing the wonders of the night sky.
