  4. Celestron CGX 800 Rowe-Ackermann Schmidt Astrograph (RASA) Telescope
    AUD $7,399.00

    In Stock

    • Flat-field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
    • Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras.
    • Ultra-Stable Focus System – precision linear ball bearing virtually eliminates image shift.
    • Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
    • Performs over a wider spectral range than most telescopes, from 400-800 nm, so more of the light passing through the astrograph is in sharp focus.
    • The CGX, with its 55 lb load capacity, is Celestron’s most innovative, state-of-the art, computerized equatorial mount to date, and provides a very sturdy and rigid platform for the fully-loaded RASA 8.
    • The drive system utilizes low cog DC Servo motors with integrated optical encoders, belt and pulley motor connection, spring-loaded steel worm gears supported by precision sealed bearings, and brass worm wheels for smooth, accurate slewing and tracking performance with little backlash.
    • Fully remote imaging capable, with optical limit switches, home sensors, through-mount cabling, and hard stops.
    • Included Celestron PWI software allows direct computer control via USB 2.0 connection.
    • Proven NexStar+ computerized telescope control technology supports functions to address imagers’ needs, such as All-Star Polar Alignment, Permanent Periodic Error Correction (PPEC), and adjustable tracking through meridian.

  5. Celestron 1100 EdgeHD SCT OTA
    AUD $6,999.00

    In Stock

    • Experience our best optical performance with EdgeHD’s aplanatic, flat field Schmidt-Cassegrain optics for pinpoint stars all the way to the edge of today’s largest imaging sensors and widest eyepieces
    • Aluminum optical tube with tube vents featuring an integrated 95-micron mesh filter allows hot air to be released from behind the primary mirror. Mirror support knobs hold the mirror in place and reduce image shift during imaging
    • Versatile design accommodates 3 focal ratios: native f/10, f/7 with the addition of a focal reducer, or ultra-fast f/2 imaging with a removable secondary mirror and third-party accessories
    • Celestron’s premium StarBright XLT coatings provide maximum light transmission
    • A 9x50 finderscope, 2” mirror diagonal for more comfortable viewing, and wide-angle 23 mm Luminos 2" eyepiece are all included

    NOTE: For solar observing the recommended solar filter is the Astrozap Glass solar filter 308-314 mm (Product Number 124447). This solar filter is a perfect fit for this OTA.

  6. Celestron Advanced VX 8 inch RASA
    AUD $5,999.00

    In Stock

    • Rowe-Ackermann Schmidt Optical Design – 8” f/2.2 flat field imaging system with rare-earth glass for outstanding images free of optical defects like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
    • Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The astrograph does not work with standard DSLR cameras.
    • Ultra-Stable Focus System – precision linear ball bearing virtually eliminates image shift.
    • Integrated air-cooling system –12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust.
    • Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
    • Performs over a wider spectral range than most telescopes, from 400-800 nm, so more of the light passing through the astrograph is in sharp focus.
    • Advanced VX, the most compact and portable of Celestron’s German equatorial mounts, offers a maximum instrument capacity of 30 lb with the same rigidity as our larger mounts and minimal flexure.
    • This mount offers every feature an astroimager wants: PEC, an autoguider port, the ability to image across the meridian, and more.
    • Dual saddle plate is compatible with narrow CG-5 dovetails and wider CGE dovetail. Also compatible with Vixen format dovetails longer than 100mm, but not compatible with Losmandy D format plates.
    • Accessories included: M42 camera adapter, C-thread camera adapter, and fan battery pack.
