Product Details

  • The PlaneWave Instruments CDK500 is a 20 inch (0.51 m) f/6.8 Corrected Dall-Kirkham Astrograph telescope. The CDK500 has a dual carbon-fiber truss design, with 3 cooling fans ejecting air from the back of the telescope. The CDK500 covers a 52 mm field of view without any field curvature, off-axis coma, or astigmatism. The instrument weight is 140 lbs (64 kg) and comes standard with a back plate retaining ring ready to accept the focuser of your choice.

    All CDK500 telescopes come with Fused Silica primary and secondary mirrors.

    The L-Series combines versatility, simplicity and affordability by combining all the technology of our Observatory class telescopes into a compact stand-alone mount. In its Alt/Az configuration it is considerably more compact than its equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure. The mass it takes to make a rigid alt/az mount is substantially less, leading to cost savings. Unlike German Equatorial mounts, there are no meridian flips to deal with, and no large protruding counterweights to create a dangerous hazard in a public observatory. Alt/Az is more intuitive to use and no polar alignment is needed. Besides, it is the way the pros do it!

    L-Series Mount Features:

    • For time frames or questions, please contact us at 800-483-6287.
    • Direct-drive motors on each axis for smooth, fast, and virtually silent movement of the telescope
    • Slew speeds up to 50 degrees per second
    • High-resolution encoders on each axis for precise positioning
    • Zero backlash
    • Zero periodic error
    • PointXP mount modeling software
    • Enclosed electronics

    The L-Series mount combines versatility, simplicity, and affordability by combining all the technology of our Observatory class telescopes into a compact stand-alone mount. In its Alt/Az configuration, it is considerably more compact than its German equatorial counterpart, allowing a larger telescope to fit in a smaller enclosure.  Unlike German Equatorial mounts, there are no meridian flips to deal with, and no large protruding counterweights to create a dangerous hazard in a public observatory. Alt/Az is more intuitive to use and no polar alignment is needed!

    Direct Drive Motors and Encoders

    Direct Drive motors and on-axis encoders eliminate the need for gears, thereby eliminating backlash and periodic error. With high-resolution encoders providing the feedback for the direct drive motors, not only will the telescope track without periodic error and backlash, but the mount will also counter wind gusts with precise servo feedback.

    Incredible Slew Speed

    The direct-drive motors can move the telescope at speeds up to 50 degrees per second for tracking satellites or just to minimize target acquisition time.

    Dual Mounting Bracket

    PlaneWave style mounting bracket to hold CDK17/20 onto inside of fork arm with the additional option of mounting a scope on the outside of the fork arm. Optional dovetail clamp required.

     

    Azimuth Dovetail Balance System

    For precise center of gravity balance whether in Alt-Az or Equatorial configuration.

    Interior Mount Cabling

    Access panels in the fork arm and azimuth axis allow for camera equipment cabling through the inside of the mount.

     

     

    Proven CDK700/PW1000 Technology

     The L-Series uses the same proven technology as the CDK700 and 1-Meter PW1000 which are being used in Universities around the world.

Speechless

All I have to say, is WOW. I'm more than happy with my purchase. I was so blown away with the capabilities of this system, that I purchased several more. *I have one set up in the backyard. *I have one set up in the front yard. *I have one set up on the right side of my palace (adjacent to my monkey-butler's quarters). *I have one set up on the left side of my palace (adjacent to the maids quarters). *I also had one installed at the BOTTOM of my pool... I just wanted to see if it was as good as the manufacturer claims it is. I figured, that if it was image deep-space objects literally MILLIONS of light-years away, and do so clearly & tack sharp, the scope should be able to see through a measly 8ft of pool water, am I right? *The 6th and final scope I purchased, I had installed adjacent to the toilet in the master-bedroom (I cut a hole in the ceiling & roof, so even when I'm taking the browns to the super-bowl, I can still image from the toilet seated position. I plan on purchasing several more, and will be giving them out for Halloween, instead of candy. I figure that a telescope is WAY better than candy, to receive in your Halloween candy-bag. Am I right?!? I'll update my review after my 17th purchase, but so far, so good. I've attached a few pics, to show you how INCREDIBLE this thing is... 1. Pic of one of the telescopes (the backyard one I think 2. Pic of me with 9ne of my awesome telescope 3. Got lucky with this shot of Jupiter (I was able to get the Earth in the same frame (I told you this telescope was awesome! Show me another scope that can image both Jupiter AND Earth at the same time!) 4. This is arguably, thesingke best image I've ever managed, of Saturn. Notice how there's almost ZERO chromatic-aberation? Super sharp focus, no? I love this telescope. I would HIGHLY recommend you buy 25 of them, just in case one breaks. Throw it away, and use one of your 24 spares (YOU'RE WELCOME for the advice). If interested, I'll be happy to send you a few in the mail, so you can test it out yourself.
