(Model: SM-RS-CDA-R, SM-CDA-R, RC-CDA-R Or CDA-R)

[ORDER NOW!]

These products are an Observatory Class Dew Heater Controller With Long Distance Remote Control Dew Removal Operation.

Typical Configuration for the SM-RS-CDA-R, SM-CDA-R, RC-CDA-R Or CDA-R  are shown below on a ritchey-chretien but can be used with any reflector, refractor, newtonian or schmidt-cassegrain telescope.



 


 


The CDA-R Family controllers can be setup with your telescope As-is placed in automatic mode for troublefree operation or can be controlled and monitored remotely via automatic or manual modes via a computer with the supplied com port interface. Astro-Smart is the innovator of this elegant automatic solution to your dew problem. The CDA-R Family controllers are one to the most advanced dew controllers made available to the amateur or professional Astronomer and at a price comparable by no other  system on the market. The CDA-R Family controllers are designed to be used with any make or model of telescope which has more features than any other dew control system being offered at a fraction of the cost.  Whether you have a refractor, newtonian, schmidt-cassegrain, or a ritchey-chretien, the CDA-R Family controllers will solve your dew problems automatically while informing you every step of the way. Its like having a hired dew specialist posted at your telescope 24/7 operating at 12V DC and supplying upto 15 Amps for dew straps.

The CDA-R Family controllers systems incorporates a common four port heater capability controlling multiple channels using multiple channel temperature sensors . For instance, one sensor(DTS-12) may be used for the main imaging telescopes corrector plate for dew control while the second(DTS-34)is used for another mounted imaging scope, guider or finder scope or your eyepieces. Each monitored sensor channel location is then paired with its associated output heat strap channel for dew control. For instance, DTS12 sensor would be placed on the optical corrector and the heat strap would go around the optical interface tube for instance CH1 or CH2 or both.

In the following pictures you can see the SM-RS-CDA-R, SM-CDA-R, RC-CDA-R or CDA-R systems with common 4 heat channels, PWM LED indicators on CH1/2/3/4 and coupled temperature sensor channels(DTS-12 for CH1/2) and (DTS-34 for CH3/4). The center ATHS channel is for ambient temperature and humidity monitoring normally placed against the optical tube of your main imaging telescope.  The RC-CDA-R system shown below adds additional features over the CDA-R such as a low voltage cutoff circuit protection with LED cutoff indicators for power supplies using battery sources and a fan cool down feature for primary mirror RC's. As an example in this configuration as shown above, DTS sensors and heater channels 1/2 would be attached to secondary while DTS sensors and heat channels 3/4 would be attached to the primary of your RC and or SCT.  With the FAN control offering for the primary, any time the temperature of primary exceeds ambient, the FAN would come on and cool the primary and turn off primary heat.

The new SM-CDA-R  system is premier all in one system which has all the features of the CDA-R plus a sky quality meter (SQM) system which informs the user of sky conditions and a intelligent computer software GUI consultant informing the user if the sky conditions are suitable for imaging, visual, technical work or too just cloudy and or presence of non steady skys due to too much atmospheric fluctuation and reflectivity. The SQM featuers of the SM-CDA-R include a graphical reporting system on the software GUI which graphically maps NELM(Naked Eye Limiting Magnitude)  and MPSAS (Magnitude Per Square Arc Sec) over a programmable measurement scale as low as 1 sample every 3 seconds. The new SM-RS-CDA-R is our ultimate flag ship system which has all the features of the SM-CDA-R plus a rain detection sensor and cutoff feature as in RC versions of the product. For more information on operation of these products, see the user manual links and video tutorial links on this page.

Since, the inception of this unique product at Astro-Smart, the CDA-R Family controllers was many years in the making, over long periods in astronomy using existing products on the market to control dew, identifying their weaknesses and limitations making the product you see before you. Features such as Patent Pending Heat Distribution which minimizes heat currents on optics during imaging,  Humidity Measurement, Dew point and Differential Temperature Alarms with automated  decision making on Dew Control, Updateable Firmware, Computer Control and Intelligent Software Computer GUI interface to name a few.  The CDA-R Family controllers are finally here!!! The Astro-Smart CDA-R Family controllers are an Observatory Class Dew Removal System designed to be user friendly, serviceable, elegant and reliable and include the following features shown in the following table: 



The PC SW remote interface snap shot main screen is shown to the left has been
tested across multiple PC operating system platforms.  The snapshot on the CDA-R Family controllers product page shows the left side window with current remote activity of all parametric values, virtual keypad and various graphs to track ambient temperature, Optic temperatures, Power Out per channel,  Dew Point and monitoring of Alarms.  As part of the CDA-R Family controllers package,  new CDA-R Family controllers purchases get the PC SW remote platform for free. Please, contact us for any questions.



The super professional version upgrade of the software increases the capability of your Computerized Dew Annihilator family to even a higher level.   This includes a data acquisition and processing suite for Multi-Channel Real Time Data Acquisition, Variable Acquisition Rate, Variable Power Distribution Algorithm Selection, Flash Memory Storage Of Critical Sensor Calibration Data, File Storage and Plot Retrieval for Extended Regression Data Analysis including .csv, .txt, .png file formats for easy interface to Office Products(Excel, etc) and a Simulator Trainer Mode. Snapshot shown below.This product upgrade software is available for a nominal  lifetime subcription fee on our purchase page.


Below is the new SQM interface tab for the Computerized Dew Annihilator family which have purchased the SQM option on any of the dew controller models. The sky quality meter (SQM) system which informs the user of sky conditions and a intelligent computer software GUI consultant informing the user if the sky conditions are suitable for imaging, visual, technical work or too just cloudy and or presence of non steady skys due to too much atmospheric fluctuation and reflectivity. The SQM featuers include a graphical reporting system on the software GUI which graphically maps NELM(Naked Eye Limiting Magnitude)  and MPSAS (Magnitude Per Square Arc Sec) over a programmable measurement scale as low as 1 sample every 3 seconds.
