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.

is passionate about. From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 20″ telescope was centered around performance and ease of use. The CDK20 is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the CDK20 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK20 is an exceptional diffraction-limited telescope.

From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 14″ telescope was centered around performance and ease of use. The CDK14 is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the CDK14 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK14 is an exceptional diffraction-limited telescope. CDK14 users can experience pinpoint stars edge-to-edge and a 70 x 70 arcminute field of view when using large 16803 size camera sensors. When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!\u003c\/p\u003e\n\u003cdiv class=\"block-feature col-sm-12\" data-mce-fragment=\"1\"\u003e\n\u003ch4 data-mce-fragment=\"1\"\u003e\u003cstrong\u003eCarbon Fiber Truss Design\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cdiv class=\"row\" data-mce-fragment=\"1\"\u003e\n\u003cdiv style=\"text-align: left;\" class=\"col-md-3 image\" data-mce-fragment=\"1\" data-mce-style=\"text-align: left;\"\u003e\u003cimg style=\"float: left;\" src=\"https:\/\/planewave.com\/wp-content\/uploads\/2018\/02\/CF-truss-295x200.jpg\" alt=\"Icon\" class=\"lazyloaded\" data-ll-status=\"loaded\" data-mce-fragment=\"1\" data-mce-style=\"float: left;\" data-mce-src=\"https:\/\/planewave.com\/wp-content\/uploads\/2018\/02\/CF-truss-295x200.jpg\" width=\"170\" height=\"115\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-md-9 col_content\" data-mce-fragment=\"1\"\u003e\n\u003cp data-mce-fragment=\"1\"\u003eMinimizes thermal expansion which causes focus shift as temperature changes during an imaging session.

From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 12.5″ telescope was centered around performance and ease of use. The CDK12.5 is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the CDK12.5 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK12.5 is an exceptional diffraction-limited telescope. CDK12.5 users can experience pinpoint stars edge-to-edge and a 70 x 70 arcminute field of view when using large 16803 size camera sensors. When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cdiv class=\"row justify-content-center\"\u003e\n\u003cdiv class=\"block-feature col-sm-12\"\u003e\n\u003cp\u003e\u003cstrong\u003eCarbon Fiber Tube Design\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv style=\"text-align: left;\" class=\"col-md-3 image\"\u003e\u003cimg height=\"211\" width=\"284\" style=\"float: left;\" src=\"https:\/\/planewave.com\/wp-content\/uploads\/2018\/02\/PW-CDK125-15-e1611284339909.jpg\" alt=\"Icon\" class=\"lazyloaded\" data-ll-status=\"loaded\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-md-9 col_content\"\u003e\n\u003cp\u003eMinimizes thermal expansion which causes focus shift as temperature changes during an imaging session.

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.

From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 20″ telescope was centered around performance and ease of use. The CDK20 is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the CDK20 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK20 is an exceptional diffraction-limited telescope. CDK20 users can experience pinpoint stars edge-to-edge and a 45 x 45 arcminute field of view when using large 16803 size camera sensors. When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"page_section block_features layout_vert\" id=\"\"\u003e\n\u003cdiv class=\"container\"\u003e\n\u003ch2\u003eCDK20's Features\u003c\/h2\u003e\n\u003cdiv class=\"row justify-content-center\"\u003e\n\u003cdiv class=\"block-feature col-sm-12\"\u003e\n\u003ch4\u003eCarbon Fiber Truss Design\u003c\/h4\u003e\n\u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-md-3 image\" style=\"text-align: left;\"\u003e\u003cimg data-ll-status=\"loaded\" class=\"lazyloaded\" alt=\"Icon\" src=\"https:\/\/planewave.com\/wp-content\/uploads\/2018\/02\/CF-truss-295x200.jpg\" width=\"207\" height=\"140\" style=\"float: left;\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-md-9 col_content\"\u003e\n\u003cp\u003eMinimizes thermal expansion which causes focus shift as temperature changes during an imaging session.

The CDK14 has a dual carbon-fiber truss design, with 3 cooling fans ejecting air from the back of the telescope, and 4 fans blowing across the boundary layer of the mirror’s surface. The CDK14 covers a 70 mm field of view without any field curvature, off-axis coma, or astigmatism. The instrument weight is 48 lbs (21.8 kg) and comes standard with a backplate retaining ring ready to accept the focuser of your choice.\u003c\/p\u003e\n\u003ch4\u003e\n\u003cstrong\u003eAll CDK14 telescopes come with\u003cspan\u003e \u003c\/span\u003e\u003ca href=\"https:\/\/planewave.com\/wp-content\/uploads\/2015\/08\/fused-silica-CDK.png\" target=\"_blank\"\u003efused silica\u003c\/a\u003e\u003c\/strong\u003e\u003cstrong\u003e\u003cspan\u003e \u003c\/span\u003eprimary and secondary mirrors. \u003c\/strong\u003e\n\u003c\/h4\u003e\n\u003cp\u003eThe 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.

From design to manufacture, our goal with the DeltaRho 350 was centered around creating a game changing wide field telescope. The DeltaRho 350 is a Cassegrain optical design which means the imaging train is secured at the back of the telescope and does not block the light path compared to prime focus designs, which severely limit users ability to operate with filterwheels, or large cameras.\u003cbr\u003e\u003cbr\u003eThe DeltaRho 350 is an incredible breakthrough in telescope technology and ease of use. Operating at f\/3 and 1050 mm focal length, the DeltaRho is a wide field telescope that is sure to revolutionize your astrophotography!\u003cbr\u003e\u003cbr\u003eAdditionally, the DeltaRho 350 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the DeltaRho 350 is an exceptional diffraction-limited telescope. DeltaRho 350 users can experience pinpoint stars edge-to-edge and a 170 x 170 arcminute field of view when using large 16803\/4040 size camera sensors. This field of view is nearly 3 times as large as our CDK14! When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThrough years of dreaming of the perfect telescope for wide-field imaging, our pursuit of innovation has finally been honored with PlaneWave’s revolutionary Delta Rho 350 f\/3 telescope. The Delta Rho 350 is designed for unsurpassed wide-field imaging and ease of use in the field. Since the primary mirror is fixed in place, collimation is quickly achieved by adjusting the tip and tilt of the secondary mirror. With the Delta Rho 350, your astrophotography experience will be second to none! \u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCorrected Cassegrain focus optical design\u003c\/li\u003e\n\u003cli\u003eAperture – 350 mm\u003c\/li\u003e\n\u003cli\u003eFocal length – 1050 mm\u003c\/li\u003e\n\u003cli\u003eFocal Ratio – f\/3\u003c\/li\u003e\n\u003cli\u003e60mm Image Circle \u0026gt; 3 degrees\u003c\/li\u003e\n\u003cli\u003eFixed Primary Mirror\u003c\/li\u003e\n\u003cli\u003eCollimation performed via 3 tip\/tilt screws at the secondary mirror\u003c\/li\u003e\n\u003cli\u003eBackfocus of 5.651” (143.535 mm) from mounting surface (without focuser and rotator).

The CDK12.5 has a dual carbon-fiber truss design, with 3 cooling fans ejecting air from the back of the telescope, and 4 fans blowing across the boundary layer of the mirror’s surface. The CDK12.5 covers a 52 mm field of view without any field curvature, off-axis coma, or astigmatism.

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.
