    Tutorials on telescope designs, some basic astronomy theory, and amateur astronomy projects for the beginner or owner of modest equipment.  
    http://www.astronomyhints.com/
    
    Extractions: Astro Links Here's a friendly place for you to hang out if you get the feeling that your small telescope just isn't big enough to do anything with. To show what you can do with a modest instrument, there are pages of observations and photographs of the moon and planets taken through instruments as small as 2 inch (50mm) aperture, and no bigger than 6 inch (150mm). Though I've been an amateur astronomer for some 45 years (and a professional astronomer for some of that time), I primarily use small and modest sized telescopes. I've been through aperture fever, having owned up to a 10 inch behemoth Newtonian on an Equatorial mount, but my biggest telescopes are 6 inch Newtonians.

If there is some light pollution at your observing site, then binoculars are essential. A roughly spherical ball of old stars (about 10 billion years old). Globular clusters typically contain hundreds of thousands of stars, and so appear as fuzzy blobs.

    Extractions: Very Large Array VLA Expansion Project (EVLA) ... Assistant Director's Page Updated 2008-Sep-26 Socorro, New Mexico, is the home of NRAO operations in New Mexico. Located on the campus of New Mexico Tech , the Array Operations Center houses scientific, engineering, technical, computer and support staff for both the Very Large Array and the Very Long Baseline Array. It includes the control center and correlator for VLBA observations and provides space for the Atacama Large Millimeter Array project. The Very Large Array (VLA) , one of the world's premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration on the Plains of San Agustin 80 km (50 miles) miles west of Socorro, New Mexico. Each antenna is 25 meters (82 feet) in diameter. The data from the antennas is combined electronically to give the resolution of an antenna 36km (22 miles) across, with the sensitivity of a dish 130 meters (426.5 feet) in diameter.

    Extractions: Project Page http://www.SignalONE.com/radioastronomy/telescope/ 5.2 Meter Radio Astronomy Project for 1420 MHz This is a description of my 1420 MHz radio telescope project for observing the natural radio emissions of neutral hydrogen atoms found throughout space. Specifically, the study of the radio spectra of these emissions is used to determine the distribution and dynamics of hydrogen throughout our galaxy. Hello, Everyone! I have been interested in radio astronomy for years but have only recently been able to find the time to assemble my own radio telescope. I have completed construction of a 5.2 meter antenna which I use to detect the 1420 Mhz radio emissions of neutral hydrogen found throughout the galaxy. I have included some information on construction and sources of material, and there is also a description of how I am using it and what type of information can be gained from these types of observations. It is my hope that this information will be helpful to others who are interested in radio astronomy or who may even be considering a project of their own. The antenna has a computer controlled Az-El mount and was built mostly from recycled C-band satellite TV components. The elevation drive was once a horizon-to-horizon drive for a 16-foot satellite TV antenna and has an integral worm drive. It is driven by a 90-vdc linear actuator motor/gearbox. The azimuth drive is a roller-chain arrangement driven by another worm drive. This worm drive is also driven by a linear actuator motor/gearbox. The antenna uses a potentiometer for azimuth position feedback which produces a voltage ratio read by a "data acquisition" board on an old 286 PC. Elevation position is obtained by using a
