Welcome to Houston Astronomical Society

Fostering the science and art of astronomy through programs that serve our membership and the community. Founded in 1955, Houston Astronomical Society is an active community of enthusiastic amateur and professional astronomers with over 70 years of history in the Houston area. Through education and outreach, our programs promote science literacy and astronomy awareness. We meet via Zoom the first Friday of each month for the General Membership Meeting and the first Thursday of the month for the Novice Meeting. Membership has a variety of benefits, including access to a secure dark site west of Houston, special interest groups that focus on particular areas of astronomy, an active community outreach program, and much more. Joining is simple.

Cool pictures of the Sun at Solar Max

Lecture and photos by Alan Friedman

By:  Alan Friedman

The sun is a unique and rewarding subject for the astrophotographer. It can be studied in different wavelengths, imaged from almost any location and can be presented in different ways to portray our star in a unique and compelling light.  The sun is now well along on its journey to maximum activity (predicted 2023-2026) and a Total Solar Eclipse visible from many locations across the United States is only weeks away on April 8, 2024. Now is the perfect time to hone our solar imaging skills for the opportunities to come. This talk will discuss technical and creative considerations in solar imaging with the goal of exercising those solar “muscles” and preparing for the increase in activity that lies just around the corner.

Bill’s presentation will focus on the nature of time itself. He will describe what we think it is, and address such questions as does time flow, can we directly measure?  How does time relate to relativity and everyday life, does it really exist at all and if it doesn't exist, why do we seem to know so much about it?

Speaker Bio: Bill Spizzirri is a retired mainframe computer software engineer who has been studying all types of science including astronomy for over 65 years. His favorite thing to do is to teach astronomy to the public, especially children. Bill has been doing this more or less continuously for over 40 years. He now does it at Houston area schools and community centers. The pay is excellent, in the form of great questions from the students.

Astrophotography can certainly be an intimidating pursuit even for experienced photographers. In this presentation, we'll show how to create beautiful images of the night sky with just a digital camera and tripod. We'll cover when and where to go, getting the best exposure, post-processing, stacking images and star tracking. There's a lot you can do with relatively simple gear. Starting out building on your successes like this will certainly help smooth the path to deep sky photography.
