Abstract
The major advantage of the project is the ease with which a celestial body may be tracked in the night sky. This gives us access to proper imaging and exploring new systems in the night sky. The telescope has an 8â aperture .This is achieved by attachment of worm-worm gear arrangement mounted of the shafts of the RA and Dec axes of the telescopic mount. To this a controlling system using PLC programmed with PLC language is used which is controlled by using an HMI. The project aims to have high accuracy and precision in object tracking. A Nema 23 Stepper motor with a 4.25 reduction gearbox has been selected. This arrangement is controlled by a 24V SMPS and 48V DC power supply. The project is economically affordable thus making it more available to the local enthusiasts.
Highlights
Automatic Equatorial Mount is made to automatically track celestial bodies in the night sky using a HMI and the entire process will be automated to obtain high end imagery and exposures ranging from 5 minutes to 6 hours
The shafts are controlled by a worm and worm gear arrangement made upon them
The worm is controlled by a gear box which is given motion by a stepper motor of 27.2 RPM
Summary
Automatic Equatorial Mount is made to automatically track celestial bodies in the night sky using a HMI and the entire process will be automated to obtain high end imagery and exposures ranging from 5 minutes to 6 hours . The worm is controlled by a gear box which is given motion by a stepper motor of 27.2 RPM. This motion is reduced to 0.05 RPM from a 4.25:1 reduction ratio gearbox attached to the output shaft of the motor. Effectiveness: The effectiveness is given by the trail marks occurring with respect to time of tracking of the object by the telescope. It has been done by placing a camera at the lens of the telescope and continuously clicking pictures and using external software for compiling them all together. Bearing used is needle bearing to withstand high radial load in our case
