CDK600 Observatory System
Enjoy exceptional optical and tracking performance for astrophotography, or research, with the CDK600 package! Includes a CDK24 optical tube and L-600 mount.
- CDK24 optical tube:
- f/6.5 and 3974 mm focal length
- No coma, no off-axis astigmatism, and no field curvature.
- Pinpoint stars across a 70mm image circle.
- Rock solid fused silica mirrors with low thermal expansion.
- Carbon fiber optical tube assembly for rigidity and fast cooling.
- Simple secondary mirror collimation thanks to the fixed primary mirror.
- L-600 direct drive mount:
- Zero periodic error, zero backlash, and minimal maintenance due to the lack of gears.
- Slew speeds up to 50 degrees/sec for satellite tracking and fast target acquisition.
- Sidereal tracking accuracy of < 0.30 arcseconds RMS over 5 minutes.
- High resolution optical encoders on both axes for precision feedback.
- Can be installed in either equatorial, or alt/az configuration.
- Includes PWI4 software (ASCOM compliant) for mount control.
The CDK24 (0.61 m) f/6.5 Corrected Dall-Kirkham Astrograph telescope has a dual truss design, with 3 cooling fans for the back of the primary mirror and 4 fans for the front surface of the primary mirror. The CDK24 covers a 70 mm field of view without any field curvature, off-axis coma, or astigmatism. The instrument weight is 240 lbs (109 kg) and comes standard with a back plate retaining ring ready to accept the focuser of your choice.
All CDK24 telescopes come with fused silica primary and secondary mirrors.
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. Besides, it is the way the pros do it!
L-Series Mount Features:
- 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
- Through the mount cabling
