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 Familiarisation" 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 his experience with that type of mount, including collimation.

And if the weather co-operates, we can use Jupiter 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 Lihres 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.  The Solar Eclipse is getting close.  Astronomy magazine has a very good set of articles about getting to the eclipse and observing safely. There is not a lot more to add except:



I hope all who wish to enjoy the eclipse have made plans.


I have found a website which has a guide to various pieces of equipment from simple to complex (and expensive!) for use during the Eclipse.  You will need to cut and paste:




If you are unable to travel to the path of Totality, there will be a 65% partial eclipse here in Houston.  The Insperity Observatory plans to be open, weather permitting, to the public.  There should be 4 telescopes, mounted on 3 piers, inside the Observatory.  (Two scopes, including a Coronado Hydrogen-alpha scope, are mounted piggy-back on one of the mounts.)


There will also likely be a few scopes in the parking lot.  There will be solar filter folding eyeglasses available.


There is in fact another option for viewing:  Any binocular ("pair of binoculars") which features solar filters in place of the normal clear objective lenses Will give a good and safe view of the eclipse.  Mine, marketed by Celestron, is a 10X42 binocular, and is nicely collimated.  Using the dioptric adjustment, it brought the sun into clear crisp focus.  There were no visible sunspots, unfortunately.  (I have now seen sunspots!  This is a useful solar binocular.)  This item cost $75 or 80 on Amazon, and was perhaps $85 or so with shipping.


Etch this on your brain:  Do not under any circumstance look at, towards, or near the sun without a professionally produced solar filter between your eyes and the Sun! Doubly exposed X-Ray film, etc, just does not protect your eyes.  Celestron says for safety, with these binoculars, they must be placed in position over your eyes, before looking at the sun.


If you have a desire to see totality on August 21, you need to be learning where you want to be, and deciding how to be there.

For example, James Billings and I are renting an RV so we can travel to Nebraska, initially.  Then the day before we will decide where along the path of totality we want to be, depending on the forecast weather, and travel to the selected location.

If you do not want to miss it, now is the time to be planning and setting up for it.  Other members are going to Wyoming, Nebraska, Tennessee, or??

This link gives historical weather along the path of totality:



This next link gives the NASA site for extensive planning information for viewing the eclipse:



If you haven't made your personal plans to be at the path of totality, you need to get on it.  From what I am hearing, hotels and campgrounds along the path are already full in some places.

Astronomy Magazine has a Bulletin of 100+ pages including around 50 pages of strip maps of the geography under the path of the totality of the eclipse, showing roads, parks, rivers, etc.  I think it is well worth the money, about $20.

They also have a Solar Eclipse Atlas which has double scale color maps of the path of totality.



 Star Party:

July 22, 2017!

Hey!  That's this Saturday!  Today!  Yikes!!


Sunset on July 22 will be at 8:23 P.M. and the moon will be down.  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:

August 19

September 16

October 21 (BBQ)

November 18

NHAC is a proud member of:

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

Insperity Observatory, Humble I.S.D.

Public Night will be on August 4, 2017


Sunset will be at  8:12 P.M.  There will be a 94% moon which will rise at 6:01 P.M. and be up all evening.  The terminator should be striking in the large telescopes at the Observatory.  Jupiter and Saturn should be nice viewing.  Jupiter is close, in Solar System terms, and is striking in the Insperity telescopes.  And Saturn will be easily seen.  The rings are open at 27 degrees, so the view is very good.


Doors will be open by about 8:00 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.
