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 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.

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.

From design to manufacture, our goal with the DeltaRho 500 was centered around creating a revolutionary wide-field telescope. The DeltaRho 500 is a Cassegrain Optical Design with the imaging train at the back of the telescope to prevent obstruction of the instrument. This offers a real advantage against prime focus designs, which can severely limit users’ ability to operate with filter wheels or large cameras. Witness the incredible breakthrough in telescope technology as the DeltaRho 500 operates at f\/3 and 1537 mm focal length, which is sure to revolutionize your astrophotography. \u003c\/p\u003e\n\u003cp\u003eLast, but not least, the DeltaRho 500 provides a flat field, which ensures stunning clarity from corner-to-corner images without field curvature degradation. The DeltaRho 500 offers the simplicity of single-mirror collimation, stray light control of advanced 3D printed baffles, and structural performance created through finite element analysis (FEA). DeltaRho 500 users can experience pinpoint stars edge-to-edge and a 2-degree field of view when using large 16803\/4040 (52mm) size camera sensors. This field of view is over twice as large as our CDK 20! This kind of equipment allows users to experience a whole new level of wide-field imaging that can bring them closer than ever to deep space. The DeltaRho 500 allows nothing to stand in between the user and amazing astro images. \u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cp\u003eAfter successfully introducing the DeltaRho 350, the DeltaRho 500 is now available for transcending the challenges of-ultra wide field imaging. With a primary mirror that is fixed in place, collimation is quickly achieved with a simple adjustment to the tip and tilt of the secondary mirror.
