The HAS Observatory

The HAS Observatory

Dark Site Observatory

 Society members enjoy dark skies at our observatory located eighty miles west of downtown Houston.  In this aerial view, you can see how our dark site earned its nickname Padhenge*. The observing field offers 38 concrete pads arranged in a circular pattern to best make use of the horizon. Electricity for powering telescope tracking devices is available within 50 feet of each pad. WiFi is available for remote telescope control or for other computer applications that require the Internet. Several star parties are held at the site each year, in addition to the Annual Picnic. Contact Walt Cooney, Field Trip & Observing Committee Chair, at FTO@astronomyhouston.org, to find out more about these events.

Camping and Facilities

The site features a Male bunkhouse that's available for overnight stays. The bunkhouse is an air-conditioned and heated building that sleeps four. Another bunkhouse has 2 rooms, designated for women and families is available. It, too, is air conditioned and heated. It has 2 beds and 2 cots in each room.  A permanent restroom building with hot water and showers is a short walk away from the observation field. Spaces are available for both tent camping and RVs.

Here you can see the attendance at a recent Star Party at the dark site.  Come out and join in the fun.

Observatory Building with Sliding Roof

The observatory building, with a sliding roof, is home to three telescopes. The south wall folds down as well, to gain full access to the southern horizon.  A few members have viewed one star of the Southern Cross from this site. The 16 x 33 main room is cinder block construction with a thick steel roof weighing an estimated 3 tons. A chart room, with its desk, reference charts, and two comfortable cots keeps its roof on for use on those cold nights.

Telescopes

Three telescopes permanently mounted inside the observatory building are available to members upon completion of a training session.  Rightmost is the most recent addition to our observatory - the Takahashi TOA-150, generously donated to the Houston Astronomical Society by Candace Williams.  This telescope is available for members to use who wish to do astrophotography with a world-class astro-imaging platform.  In addition, the telescope will be used to conduct live-streamed outreach events directly from the HAS observatory.

The telescope in the center is a Celestron-C14 mounted on an Astro-Physics AP-900 mount that is used extensively for visual observing. The telescope is being run by TheSkyX Pro for GoTo capability or the hand paddle for star hopping.  For most, this is the first telescope in the observatory they are trained on.

The telescope on the left is a recently acquired Paramount ME mount upon which 16" Ritchey–Chrétien has been mounted.  This telescope is a GoTo “robotic mount” which must be controlled either by computer control or the electronic hand paddle. This telescope is used to collect data for use in scientific studies.  

Dark Site and Observatory Access

The HAS Dark Site is available to all members in good standing who have:

1.        Paid their current year’s dues.
2.        Completed the online site orientation training.

The HAS Observatory is available to members who have completed an additional training course on usage of the building.  To be eligible to attend an Observatory Training Course, members must be at least 16 years of age, be up-to-date with the Dark Site orientation and be a member in good standing for a minimum of six months.  Those interested in attending this training who are under the age of 18 must be accompanied by a parent or guardian who is also a member.  Underage members whose parents are not members may attend the training, but will not be eligible to use the observatory unless supervised by a trained adult user.

Prior to observatory training, users are required to have:

  • Knowledge of basic telescope functionality and procedures.
  • Working understanding of equatorial-mounted astronomical telescopes.
  • Know how to read star charts and locate/identify constellations in the night sky.
  • It is also strongly recommended, though not required, that users be familiar with using TheSkyX software.

2/15/2024 ON HOLD: The weather has been uncooperative and we have not been able to train sufficient trainers to conduct these classes. Evidently, folks have day jobs ;) But we will continue exploring ways around this issue. If you'd like to be part of the solution, please contact Walt Cooney at WaltC@astronomyhouston.org for information.

Training to use the TAK TOA-150 telescope for imaging requires a separate training orientation which is open to those who have completed the Observatory training. 

All training sessions are at the discretion of the Observatory Director. Contact Observatory Director Chris Ober for more information. Training sessions are on a first come, first served basis and are announced in the HAS email list, website and Facebook group. We are not maintaining waiting lists for training.
