What is the Wheaton Telescope?

The Wheaton Telescope is a fully internet remote controlled telescope, housed in Grove Creek's remote controlled western sliding-roof observatory, 30 meters (100 feet) west of the main domed observatory. It is a research and educational facility run as a joint collaboration between Wheaton College in Norton, MA, USA, Andrew Mattingly and the Grove Creek Observatory in New South Wales, Australia.

History:

After meeting with Professor Tim Barker of Wheaton College, during his visit to Grove Creek in October 2003, a 30.5cm (12") Meade LX-200 (Classic Model) Schmidt Cassegrain Telescope, SBIG ST-8XE CCD camera and accessories were shipped to Australia and installed on the 20th of January, 2004. Within 6 months, the upgrades to make the existing observatory fully remote controlled were completed and the project became fully operational on July 1st, 2004. The 12" LX-200 was initially run only as a "test bed" to design and build a totally unique and user-friendly remote internet observatory for Wheaton College students. However, the results went far beyond expectations and was very popular among the students and the facility, during its 2.5 year operation. The facility provided a valuable research tool and real opportunity to do astronomical research - not only for under-graduates but thesis and independent study work, which was carried out with the project. Wheaton College supplied the telescope, SBIG ST-8XE CCD imaging camera and accessories, as well as jointly funding the ongoing maintenance costs and expenses of the project. In September 2006, it was decided to decommission the 12" LX-200 due to the lack of available repair parts, after running the telescope full time for over 17,470 hours non-stop (and several blown motors and motherboards).

Funding was then made available by Wheaton College to upgrade the facility to a sophisticated and larger Meade 14" (35.5cm) RCX-400 telescope. These are Ritchey-Chrétien optical designs, providing flat images to the edge of the field of view with a focal ratio of f/8 and have far superior optics than the previous Schmidt Cassegrain models. They also include many more electronic features, that were unavailable in previous models and some new interface programming was required to bring the telescope online for full remote operation. To compliment this new telescope, a SBIG STL-1001E large format CCD Camera with 2" BVR filters were purchased for it and the new telescope was installed at Grove Creek on the 29th of January, 2007. However, the telescope was only operational for 6 months before an encoder motor broke and as of May, 2008, the telescope is still in the shop awaiting parts from Meade... In the mean time, a privately owned 10" Meade LX-200 GPS model is being use at f/10, which provides a similar image scale (pixel ratio) as the RCX-400 14" @f/8.

The entire remote control operation was designed and programmed by Andrew Mattingly, Project Manager of the Wheaton remote controlled telescope. He is a leader in this field - with many years of computer experience, holding a high position at IBM Australia and has extensive programming knowledge of telescope and CCD imaging scripting software. Mr. Mattingly jointly funds the ongoing funding of the maintenance costs and expenses of the project with Wheaton College. He also donated the cost of motorising Grove Creek's existing western sliding roof observatory, control electronics, computer software integration, the Telescope Control Computer and the wireless weather station. He also operates the Sydney Web Server - where users log in via the internet to operate the telescope.

The observatory building, video cameras and some of the computer systems and accessories were provided by the Grove Creek Observatory, a non-profit facility, which is run by Observatory Director, Jim Lynch and Managing Astronomer, Steven Williams. Online computer video surveillance security and 4 security cameras were donated and installed by Jeff Brooks from "CrimeWatch Digital Security Solutions". Other computer hardware and accessories donated to the project by individual Grove Creek staff. The project is maintained by Grove Creek Observatory's volunteer staff "at cost" - for the enjoyment of providing a service to Wheaton students, who are in the Northern Hemisphere, that do not have access to the Southern Sky.

How does the Wheaton Telescope Work?

Three computers control the operation:

1 - The Telescope Control Computer
2 - The Observatory Server
3 - The Sydney Web Server

The "Telescope Control Computer" is located in the remote controlled observatory at Grove Creek. It controls the telescope pointing (within 1arc minute accuracy), CCD camera, Optec temperature compensated auto-focuser, monitoring light for the telescope status video camera and the Observatory's motorised sliding roof. The pointing accuracy of the system is done by automatically taking a short, low resolution CCD image through the telescope and then the software automatically compares that to how it should appear in a huge stellar catalogue. If the stars from the image do not match the catalogue, the telescope is "jogged" to the exact location of the night sky. This sort of accuracy is essential for automatic Super-Nova hunting and finding/mapping minor planets or asteroids. The "Telescope Control Computer" is connected via an underground Ethernet cable to the "Observatory Server", located 30 meters away in the main building's control room.

The western remote controlled building at Grove Creek:

The roof opens from the middle, with 2 motors on the southern side, remote controlling each half of the roof.
This building is located 30 meters west of the main domed observatory,
measuring 5.6 meters x 4.6 meters

Roof Motors:

'The "Observatory Server" constantly sends out data from our Weather Station and Boltwood Cloud Sensor to the "Telescope Control Computer" for roof control, with software and relay hardware to control the roof motors. The Boltwood Cloud Sensor not only monitors cloud conditions but it is so sensitive, that only a tiny sprinkling of rain is needed to instantly trigger the observatory roof to close and lock. The weather station, via the Observatory Server, will also signal the Telescope Control Computer to trip the roof relays to automatically close if rain is detected, the humidity becomes too high, high winds are present, the internet connection is lost or if the sun is about to rise. The "Observatory Server" is also responsible for the remote controlled security video cameras to safeguard the entire facility, which provide constant video surveillance - triggered by automatic motion detectors. A sophisticated back-to-base alarm system with video, motion detection and infra-red sensors are also incorporated at Grove Creek (protected by battery backup and UPS systems) to guard the Observatory against possible intruders. (Thanks very much to Fordray Electronics in Orange, for the donation of the alarm system and also thanks to Greg Ford, who installed it at Grove Creek).

The Weather Station and Cloud Sensor - Protecting the Remote Observatories:

We use the Oregon Scientific, model WMR918, wireless professional weather station (shown above) to safeguard the remote observatories. The Boltwood Cloud Sensor is the white angled tube, shown on top of the weather mast. The weather station also provides the Trunkey Creek area with helpful online weather information and detailed historic data. For this, we use the FreeWX Weather Software written by Andy Keir, which reads the data from the serial port on the weather station to display useful weather data in a graphical form as well as uploading the data via FTP, to our Online Weather Web Page.

The "Sydney Web Server" is where all the magic comes together! It receives the raw data from the "Telescope Control Computer" via our broadband satellite internet connection at the Observatory. The facility is very remote and ADSL is not available. It enables account holders to login and operated the telescope to take CCD images via the Internet, just using a simple web browser! This is a break-through in remote telescope operation, as other remote controlled telescope operations require users to have detailed knowledge of both telescope pointing control software and CCD Camera imaging software. However, with the Wheaton Telescope, no special software is required at all! The web user interface is extremely user friendly and very powerful, containing a huge database of catalogued objects and compatible with any internet browser software.

In summary, the Wheaton Telescope at Grove Creek is totally unique in its operation. Powerful, sophisticated, fully self-protected but still easy to use - from the novice to the professional astronomer. Users just enter their desired object from millions of objects and the image will be taken for them - always landing right in the middle of the CCD field of view. Or, the server can suggest a large number of interesting objects to the student to study. This is not just taking "pretty pictures" - many important research programs have been conducted with the Wheaton Telescope, including the search for Gamma Ray Burst Stars and the search for near earth orbit crossing asteroids - along with many other important astronomical projects.
