    ASLC Information Packet Welcome To The Astronomical Society Of Las Cruces Greetings from the nearly 100 professional and amateur astronomers who comprise the Astronomical Society of Las Cruces (ASLC). Whether you’re new to astronomy or a seasoned veteran, we hope you’ll find participation in the ASLC to be both enjoyable and fulfilling. The club was formed in 1951 by a group of dedicated astronomers including Clyde Tombaugh, who had discovered Pluto just 21 years earlier. For over 50 years, we’ve been sharing the universe with our community under our beautiful Southern New Several members of the club do astrophotography. This Mexico skies. image of the Andromeda galaxy is by Dave Dockery ASLC has active observing, education and public outreach programs. We host a public Moongaze each month, offer adult education courses and support countless star parties for local schools, scouts and various organizations. In addition, we hold a meeting each month featuring a presentation by one of our members or an invited guest. ASLC members support clinics to help new telescope owners learn how to use their equipment. And for individuals who don’t yet have equipment, we offer telescope making workshops. Many of our amateur members go On Saturday evenings around the first quarter beyond observing and collect scientific data on minor moon,club members and the public gather in front of The International Delights Cafe for our monthly Moongaze planets and variable stars.

Depuis plus de mille ans, l’hypothèse anthropomorphique de la prépondérance idéale de l’homme et de la femme a joué le jeu des entonnoirs d’idées nouvelles, d’expériences nouvelles. Ainsi la prevalence de l’idée que la terre étant le centre du monde impliquait que le soleil tournait autour de la terre a causé le schisme entre Galilee et l’Église catholique romaine, et plusieurs dont Giordano Bruno furent brulés en son nom.

  • The Texas Star Party 1999 Telescope Observing Club
    THE TEXAS STAR PARTY 1999 TELESCOPE OBSERVING CLUB BY JOHN WAGONER AMERICAN ASSOCIATION OF AMATEUR ASTRONOMERS RULES AND REGULATIONS Welcome to the Texas Star Party’s Telescope Observing Club. The purpose of this club is not to test your observing skills by throwing the toughest objects at you that are hard to see under any conditions, but to give you an opportunity to observe 25 showcase objects under the ideal conditions of these pristine West Texas skies, thus displaying them to their best advantage. This year, we are putting the “party” back in Texas Star Party. We’re having a “planetary party”. No, not the bodies that orbit the sun, but those little gas thingies in deep space. The rules are simple. Just observe any 25 of the 49 planetaries listed, and log those observations in the spaces below. That’s it. Any size telescope can be used. All observations must be made at the Texas Star Party to qualify. All objects are within range of small to medium sized telescopes, and are available for observation between 1O:OOPM and 4:OOAM any time during the TSP. Small telescope owners should pay close attention to the size and magnitude of the planetaries selected for observation. All objects are listed in Right Ascension order so that you can observe them before they set in the West, or as they rise in the East. Each person completing this list will receive an official Texas Star Party Telescope Observing Club lapel pin. These pins are not sold at the TSP and can only be acquired by completing the program, so wear them proudly.

  • 2021 the Best of the Rest of the Advanced Observing Programs II
    The Texas Star Party - Advanced Observing Program - 2021 The Best of the Rest of the Advanced Observing Programs This year, 2021 gets us back under the stars at night, but the star party functions are conducted virtually as the in- person gathering at the Prude Ranch has been cancelled due to Covid-19. This year’s Advanced Observing Program will be conducted from an observing site of your choosing - Details will follow below. The observing program is a continuation of the twentieth year of the advanced visual observing programs of the Texas Star Party. Normally I would not present one, and certainly not two “Best-of” programs as they only cover ground previously trodden, but two years ago I got talked into it and everybody seemed to enjoy the variety of targets presented. Therefore, for this year’s abbreviated star party I am going with the Best of the Rest, of the Advanced Observing programs, or as some would say, The Best of the Advanced Observing Programs - Part II. This year highlighted are 40 of some of the brighter and more interesting objects that have been listed over the previous years. This is - by far - the EASIEST Advanced TSP list ever published, and will provide some “eye-candy” as a reward for those of you who may have experienced “retinal torture” in the past. With just a little extra effort and a good sky, an advanced observer may be able to visually see ALL of the objects using only a modest aperture telescope. In planning your observations, pay attention to both the listed magnitudes and the object size, which will give an indication of the surface brightness of each object.
