A Heads up for a special event in August!


We will be holding a special event in lieu of our regularly scheduled Novice session and General Meeting.  We will be hosting a "Telescope Familiarization" event designed for all astronomers, ranging from Novices wanting to learn, to highly experienced astronomers who are continuing to learn. We will be meeting at 6:30 and are planning to stay for as long as it is fun. We expect to start with a short general introduction to the types of telescopes most of us generally use, followed by breaking up into groups based on the type of telescope you have.

If you have any questions at all about a recently purchased telescope/mount,

bring it.Bring it! BRING IT!!


There will be someone there to share their experience with that type of mount, including collimation.

And if the weather cooperates, we can use Saturn as a target to practice with our scopes.


Did I mention to bring a telescope?

 3.   Follow-up Item:  Spectroscopy at Insperity.


At this point we believe the spectroscope and the cameras are functioning correctly.  The issue at this point is to have reliable communication between the computer and the mount with the 16" telescope.  In the meantime we are working on learning the LISA program which was written by a member of the European Space Agency Optics Team.  This program takes a correctly exposed spectroscopic image and converts it to data suitable for inclusion in databanks which are used for research by the professional Astronomers.


If none of this makes any sense, do not feel alone.  There is a good discussion and illustration of  the spectroscope and how it works on pages 5-6 in the Lhires III user guide found at:


Further information is available in the introductory manual by Ken M. Harrison, available from Amazon, entitled "Grating Spectroscopes and How to Use Them".


If you would like to join our working group or simply learn something about Spectroscopy, let me know by email and I will include you in my group emails.


4.  For all members, please remember to pick up your Name Badge before the meeting, wear it, and return it after this meeting so you will still have a name tag at the next meeting.  We do not want any members to be nameless.

6.  I apologize for this newsletter being late. I have  been on the road for the eclipse, and did not realize my observing location would be out of cell coverage by quite a bit. In spite of my desire to get this out, it has been a challenge.


 Star Party:

September 16, 2017


Sunset on September 16 will be at 7:46 P.M. and the moon will not rise until 3:24. A.M. If the weather cooperates, it should be a very nice evening for observing.


If you are new to the club  this event is especially for you.  We, the members, are the reason we have observing events such as this, and it is a great occasion to get familiar with observing.  We do have 10" Dobsonian scopes available at the Dark Site for your use, and there will be several other scopes available for all to try.  And do bring a Binocular-- you can do lots of successful observing with nothing more.


NHAC Club Policy is that the focus of the Star Parties will be to give as much assistance as possible to new observers.


For those who may not have been to the O'Brien Dark Site, it is just north of Dobbin, which is on Highway 105 west of Montgomery.  It has reasonably dark skies, and a great low horizon in all directions.  The Owners, Tim and Wanda O'Brien are very generous hosts, and they do turn off any outside lights which might bother us, if we remember to ask.


The specific Dark Site location is password protected.  Any club officer can give you the password, but it is


Access to the Dark Site must be requested from the O'Briens in advance.


On our NHAC web site, click on "Observing" then select "O'Brien Dark Site".  Scroll down to the O'Brien Dark Site information and look for the "detailed directions" link.  You will need to enter the password.  There are maps as well as directions.  It is well worth the drive, which is about 6 or 7 minutes driving time North of Dobbin off of State Highway 105 west of Montgomery.


Star Parties are routinely scheduled for the Saturday on, just before, or just after the New Moon throughout the year.  This is to provide the best opportunity for dark skies.

The anticipated schedule for the remaining 2017 Star Parties, subject to change, is:

September 16

October 21 (BBQ)

November 18

Astronomical League/NASA Night Sky Network/International Dark-Sky Association

Insperity Observatory, Humble I.S.D.

Public Night will be on Friday, September. 1, 2017

Sunset will be at  7:43 P.M.  There will be a 84% moon which will be up all evening.  The terminator should be striking in the large telescopes at the Observatory.  Jupiter is getting low in the west, and will not be visible much if at all.  But Saturn should be nice viewing. The rings are open at 27 degrees, so the view is very good.


Doors will be open by about 7:30 P.M. and remain open to the public until 10:00 P.M.


These Public Nights are a tremendous opportunity for us to be a part of Astronomy Outreach, and also to observe with scopes we might never get to use, otherwise.  The Observatory has a 16" and a 20" telescope. We have recently aquired a 5" Takahashi refractor, a very high quality observing and imaging instrument.  Each is computer controlled, which provide awesome views of the sky.  There are usually about 75 guests, sometimes more, on Public Night, with several repeating.  Our guests are very appreciative of the opportunity to enjoy and also expose their kids to Astronomy.  Then after all our guests have departed, several of us usually stay for a while and enjoy the views and each other's company.


The Observatory is about 3/4 of a mile south of Will Clayton Parkway on S. Houston Ave, just north of Rankin Road in Humble, in the back part of the Jack Fields Elementary School on the East side of S. Houston Ave.  For information, see the web site or the address below.


Dates and times are subject to change.

The North Houston Astronomy Club (NHAC), was formed for educational and scientific purposes, for people of all races, creeds, ethnic backgrounds and sex, for the primary purpose of developing and implementing programs designed to increase the awareness and knowledge of astronomy, especially for those living near the north side of Houston Texas.

NHAC is a not-for-profit organization dedicated to providing the opportunity for all individuals to pursue the science of astronomy, by observing in a dark-sky site, learning the latest technology, and sharing their knowledge and experience. Thus, our “Observe-Learn-Share” motto.

The North Houston Astronomy Club is a not-for-profit organization sponsored by Lone Star College-Kingwood, dedicated to increasing the awareness and knowledge of the science of astronomy. Public meetings are normally held each month on the fourth Friday.  In the months of October, November and December they are usually rescheduled for the third Friday of each month, so as to not conflict with the Annual All Clubs meeting, Thanksgiving, or Christmas.
