San Antonio League of Sidewalk Astronomers

San Antonio League of Sidewalk Astronomers


I met one or two of you last year at an event in Floresville. I've never had so much as a Wal-Mart desktop telescope, but for my birthday my wife is giving me permission to spend some money on a good telescope. I was looking at the Celestron Nexstar Evolution 8 203mm f/10 EdgeHD Aplanatic Cassegrain go to telescope with Starsense autoalign. Would love any feedback or suggestions from a group who has more experience with this.
“Happy New year 2021” The thesis Reward for the USA People & It for Scientific Global: On rule of Philosophy I Find Eventful Universe is the Magic of the God/Allah- Mind Blowing & Amazing Facts: The thesis understudying the Universe & Cosmology easy way to in English, code of law my theories with strong power of philosophy of faculty of sciences and finally fulfillments find out the Universe Creations& Finality able to see our Creator! Theory: “Own Mind & Location is the Present and Past for All” In this way- Philosophers finally found- Eventful Universe is the Magic of the God/Allah- Mind Blowing Facts about the Universe. Nature’s plan in everything is the Play of faculty/Imagination. 1stcase was the birth of the Universe not the Big Bang, Birth of the Universe 2ndcase was the Big Bang and 3rd case was the evolution. Observatory Scientists are seeking the Big Bang nearly 14 billion years past from us yet! With my theory and philosophy- I was looking at the Big Bang at this place. Again found- the Magic of philosophy- Same moment or event- there are two cases of the Universe. Just at this moment or event everything has created again the same event or very moment nothing created in the Universe. We are looking at the Big Universe again; it is infinitesimal. On the Rule of Science- Looking at the Universe is 14 billion years past from us, again on rule of my theory with philosophy- I am looking our Universe is in my Brain’s molecules. Age of the Universe is nearly 14 billion years yet! On rule my theory with philosophy I find the age of the Universe is yours life-time and life-less position is in the Dark Energy. We and our eventful Universe is copy such like CD and Digital Universe, Real copy is in power of faculty or in imagination power of the God/Allah/Infinite. Again find out- We everybody is the Universe & Location of Home planet center point in the Universe because- we are here. Also our Sun is centered from the Sun location. You are center point from your location & I’m center point from my location yet my very Brain is Centre of the Universe. Also your brain is Centre yet when you fulfillment is understood following URLs thesis- A New World & Universe to Explore Alone. Then you can tell that- My very Brain is the Centre & Only way of Portal to the Universe. At: Consequently lawful- finally we can take the resolution that- Science Transcending Boundaries 14 billion past from us yet! The power of philosophy of faculty or Imagination Power is above the Science Transcending Boundaries. Science cannot find out what happened before the Big Bang Yet! On rule Philosophy of faculty find that the case. In order of merit found realism- So can say that- Who is a World frontier of Philosophy of Faculty of Sciences!
So what have you been doing during the quarantine? Linda Prince and I (both members of Amateur Observers’ of New York, a Long Island astronomy club, created this page: City of Stars - New York City. It’s about the astronomy related sites in NYC and a couple just outside of it. More about that in the page. I know if you live far from NYC, you probably won’t be visiting it anytime soon but you can do this virtual tour and maybe visit it later. If you live nearby, you might make it to some of the sites sooner rather than later. Either way we hope you enjoy the page. Maybe you could create one about your area. If you do, let us know.
Want to learn about the Library Telescope Program and the new Astronomical League Library Telescope Award? If so, this event is for you.
I've posed on your website 2 times already, I'm new at this, I need help setting up my telescope and equatorial mount with my computer and camera. I've gone to Wednesday nites at McAllister park 3 times now to meet and greet and ask for help, no-one, crickets. Have ya'll disbanded? Can anyone help? Name a price I can pay for your services. PLEASE, e-mail me at [email protected] or call me at 901 849-5036 (leave call back # and message) or send me a letter: Jack McGarrity, 6771 Wayman Ridge, Live Oak, Tx 78233. I really really want to get into this hobby and go to dark sky reserves for photography. I bought all my gear at Scientific Analytical but they are "understaffed and too busy" Thanks, anyone.
Going camping in Kickapoo Cavern State Park in October has anyone done any stargazing there? If so how was it?
Hello all, I'm a newbe and was wandering where were some good viewing locations in and around San Antonio?
All of my links to get into the member forum appear to be broken. Is anyone else having problems?
I was out looking at Mars a little bit ago before the moon brighted the sky and just so happened to catch a quick passing light in front, the opposite direction of the moon's orbit. I am almost positive it was artificial. It was not a meteor. Could it have been a satellite or maybe the ISS? How would I know the difference between those two? Tia for the help.
Earthbound Astronomer is excited to bring you our first Texas State Park Excursion Event. Join fellow astronomers from around Central Texas August 3-5 at Kickapoo Cavern State Park to observe the grandeur of a Bortle-2 sky and the 2018 Opposition of Mars.

January full moon 2021: The 'Wolf Moon' rises with winter constellations The full moon of January, called the Wolf Moon, will occur on Thursday, Jan. 28, at 2:16 p.m. EST (1916 GMT).

On 7 January 1610, Galileo used his telescope to first record what he described as small stars, all very close to Jupiter. Over the next few nights he charted their motions, determining these were actually captured “wards of Jupiter.” He named the group of four the Medicean stars, after his sponsors, but we now call them the Galilean moons, after him. Their names, from closest to farthest from their host planet: Io, Europa, Ganymede, and Callisto. The December 2020 Great Jupiter-Saturn conjunction put them on beautiful display. Happy Birthday to the science of optical astronomy!

Jupiter & Saturn Conjunction
For those who are waiting for December 21st, to view the Jupiter / Saturn “great Conjunction”; don’t wait. You can start to observe this event now while they are both still higher in the SW sky. For instance, tonight (here in Nashville), at 5:15 it is easily dark enough to spot these two bright gas giants about 19 degrees above the horizon. See the illustration on how to approximate that using your hands. The sky image shows a field of view where both planets can be observed or imaged with a 100mm (4”) f/5 telescope. The round field of view is with a wide field 31mm Nagler and the rectangular view is with a full frame DSLR on the same scope. If the sky is clear, look up tonight (and the coming nights), naked eye, with binoculars or small scope to start watching the progression of this spectacular event.

The Great Conjunction approaches! Jupiter and Saturn enter the same field in low power eyepiece about December 11.

A Celestial Spectacular to Close out a Chaotic Year
Jupiter-Saturn Conjunction Dec 16-25!
After what may go down in history as one of the most chaotic years in human experience, we will depart from this year of 2020 with what can summarized as a once in a lifetime Spectacular Sky Show this December.
Forget the virus, the politics, the disrespect throughout humanity:
THIS is the show.
For over 800 years we have waited until two of the brightest planets will appear to MERGE into one in the sky creating remarkable “star” for the Christmas season.
Over the next weeks, from now until after December 25, the
two very bright planets Jupiter and Saturn will close in on one-another as we gaze at them from Earth and appear to actually merge together as seen with the naked eye into one bright orb in the southwestern skies after sunset. It will be a surreal holiday experience that you will not want to miss, something that rarely can happen in anyone's lifetime.

FULL DETAILS and charts are found at the Arkansas Sky Observatories’ website:

If you have a telescope or good binoculars you are in for an even greater treat as BOTH the gas giant Jupiter and ringed Saturn will easily appear together within a single field of high power view, showing many moons and each planet's surface features.

Wishing all of you a very Happy and Safe Thanksgiving!

This asteroid just skimmed Earth’s atmosphere | The asteroid - 2020 VT4 - is estimated to be between 16 and 36 feet (5-11 meters). It skimmed the top of our atmosphere on Friday, November 13, 2020. Astronomers spotted it one day later.

One more planet parade of this year is coming in November 2020 🪐

In the middle of November, observers from the Earth will see all eight planets of the Solar System! Even though there is no official scientific definition of the term “planet parade”, it’s used in astronomy to denote an astronomical event that happens when planets of the Solar system line up in a row in the same area of the sky, as seen from the Earth. 🌏

On November evenings Jupiter and Saturn are shining at an apparent visual magnitude of -2,1 and 0,6, respectively. A dwarf planet Pluto will be near the gas giant Jupiter, but it’s barely possible to see with an unaided eye since the dwarf planet will be shining at a magnitude of 14,5. ✨

But the bright red Mars will stay visible in the sky all night long (-1,7m), and with the help of even a small telescope, you can see Neptune (8m), Uranus (6m), and the second dwarf planet — Ceres (9m). Venus (-4m) and Mercury(-0,7m) will rise above the horizon in the morning. However, Mercury will be visible only until mid-November — after this, the planet will be too close to the Sun. ☀️

A rare and unique planet parade already took place on July 4, 2020. This one will be less significant but still worth your attention. More about a planet parade, it’s definitions, and what exactly you should expect during this event, read in our previous article ➡️

ESA European Space History

On this day: 25 August 1609, Galileo Galilei made the first recorded demonstration of an early telescope, with a magnification of about 8 or 9, to Venetian lawmakers. Based on rough descriptions of the first practical telescope (which Hans Lippershey tried to patent in the Netherlands in 1608), Galileo had made a telescope with about 3x magnification. He later improved this with versions with up to about 30x magnification. By in March 1610, he had published his first astronomical observations by telescope in a paper called Sidereus Nuncius.

Comet F3 NEOWISE has survived its plunge around the Sun and is ready to move from the dawn sky to the early evening sky. It is visible through binoculars, and observers say it can be seen with the eye alone if the sky is dark enough. Find out more information, including how to see comet at

[06/16/20]   Inspiring young people to explore and appreciate the night sky is a huge part of amateur astronomy. One of our members tell this story:

"Two weeks ago a five-year-old and eight-year-old and their parents were at my ranch. They wanted to look through my telescope. Within 20 minutes, with supervision, the older one had mastered the Dobsonian scope and spent the evening finding wonders in the sky. I heard a lot of 'awesome,' 'so cool' and other positive comments. It was easy to get them interested by first showing them constellations and telling what to look for in them. They really liked Saturn and Jupiter. The next week when the older one came over, the first words he spoke to me were 'Hi. Can we look through the scope tonight!?'"

"A little effort can get children interested in the sky and science. It was also fun for me to see them so enthused."
