 >>>>Very Important Special Notice:<<<<


Due to Hurricane Harvey flood damage at the LSC Kingwood Campus, we have had to move our meetings for the forseeable future to temporary "quarters" at the Lone Star

College Montgomery Campus.


The campus is located on State Highway 242, just west of IH45.  This is basically the north side of The Woodlands.  The LSC Montgomery campus is on the North side of SH 242, just west of IH 45.  We will meet in Room B-102.  B-102 is on the ground floor of Bldg. B, adjacent to the Parking Garage on the west end of the Montgomery Campus, at the back corner.

The Novice Sessions will be held in Room B-203, on the second floor almost exactly above Room  B-102.


Snacks will continue to be the Subway Sandwiches, with volunteers welcome to help with the pickup of the food.  The cost will be paid out of voluntary contributions from previous meetings.  We are paying for it ourselves, in other words.


This posting will be continued for as long as we are meeting at the Montgomery Campus, LSC.

2.  Our Astronomical League Coordinator is Dr. Aaron Clevenson.  The Astronomical League URL is:


A recently announced new program is the Mars Observing Program.  It is designed for visual observations as well as imaging, and the window for good observations begins in February.  There will be more details on the Astrolist list server, but now is the time to begin planning. There are observations of various features and effects.  This summer is expected to be a great apparition of Mars, so don't miss out on this opportunity.


Another recent addition to the Observing Programs from the AL includes the Master Observer Progression.  It has 6 levels, and is designed to provide a road-map and recognition from novice through expert. It starts with the Observer Award for the newbees.  After you complete 5 introductory level Observing Programs, you will be recognized.  Master Observer is for those attaining 10 certifications.  It goes up from there through Advanced Observer, Master Observer - Silver, Master Observer - Gold, and Master Observer - Platinum.  There is also a new Binocular Master Observer for those who prefer binocular observations.  Check out the Astronomical League website:


NASA and the AL are also preparing 3 more NASA Observing Challenges for 2018.  they will include observing the Sun, Mars, and a star with an extrasolar planet.  More info to come.


So what is holding you back?  Opportunities abound, and the more experienced members of your astronomy club are here to help you start your journey.  If I can help, please email me: <>


3.   Follow-up Item:  Spectroscopy at Insperity.

For those interested in learning about Spectroscopy, Dr. Bruce Pollard, PhD, NHAC, is our expert.  There is an ongoing program to develop the Spectroscopy program at Insperity,  and Bruce is a very effective teacher.


If you would like to do hands-on learning about Amateur Spectroscopy using an effective but inexpensive grating filter, information is available in the introductory manual by Ken M. Harrison, available from Amazon, entitled "Grating Spectroscopes and How to Use Them".  It is detailed, and full of good information.


And as it happens, there is a very apropos article in the September issue of Sky and Telescope Magazine about RSpec, a real time spectroscopy program which is affordable and can be used to process and examine Spectrographic images.  The developer of the program, Tom Fields, also sells the Star Analyzer grating filters which I am currently using.  This is an excellent "how to get started" article. It is on Page 68.


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.

Star party and Bar-Be-Que

October 6, 2018


This month the Star Party is 2 days prior to the New Moon.   Sunset will be 7:02 P.M.  The moon will not rise until 5:37 in the morning.


As usual, please plan to let James know how many folks you are coming with, and how many hot dogs or hamburgers you will want.  Yes, you can have both!  He will want to know that about Thursday the 4th so he can plan.


We expect to fire up the grill about 4:30-4:45, start cooking shortly thereafter, and stop serving about 6:pm.  This should allow ample time to clean up if everyone pitches in.  It is nice to bring dessert items, salad and vegetable dishes, and any other specialty items to the Bar-Be-Que.  Please plan to trash or return home any items which are left when we start cleaning up.  It really helps if everything can be cleaned up and put away before sunset.


At 7:32 P.M. Venus will be about 3.4° above the horizon, and very bright. If you can pick it up before it sets, you will see it has a very crescent appearance due to its position.  This will likely be your last chance this year to see it in the evening.  Later in October it will become the Morning Star.


Jupiter will be Southwest, about 17° above the horizon. Saturn will be SSW, about 35° up. Mars will be SSE, and 33° up.  It will bright also, but it is getting smaller as time goes on and it gets further away from us.  Pluto will be 37° up in the South, but as always faint.  Neptune can also be seen, WSW, and 23° up.


To emphasize, if you have wanted to see Saturn's rings, now is a good time.  They are "open" and spectacular!


Constellations of note visible in the early evening include Scorpius, Sagittarius, Ophiuchus, Hercules, Aquila, Cygnus, Lyra, Pegasus, Andromeda, Aquarius, and Pisces as the evening goes on.Towards the North you can see Ursa Minor, Cepheus, Cassiopeia, and Triangulum.


For the Messier hunters, the sky is rich and now is the time to catch those in the Scorpius and Sagittarius part of the sky.  From West (setting) to East (rising) now is the time to catch these Messier objects: 4, 80, 6, 7, 23, 20, 8, 21, 17, 18, 28, 25, 27, 69, 70, 54, 55, and 75.  Be sure to log the date and time for any you see, together with any other interesting details.


With my 9.25" SCT scope this past week I was able to take a good un-rushed look at M31, the Andromeda Galaxy, and her 2 very close Satellite Galaxies M32 and M110.  I was able to go back and forth between the 3 of them repeatedly to compare 32 and 110's appearances and learn how they differ.  It was fun to be learning something.  I expect anyone with a 6 inch or larger scope can see all three of them.  For 31, of course, you can see it naked eye and nicely in binoculars.


The Summer Triangle of Deneb in Cygnus, Vega in Lyra, and Altair in Aquila will be well up overhead.  In Cygnus, Albireo, a gorgeous bi-color double star can easily be seen a couple of hours after Sunset.


It will also be possible to find and enjoy the Double Cluster between Perseus and Cassiopeia with binoculars.


October is getting cooler, and we are due for some nicer weather.  Let's hope....


If you are new to the club these events are especially for you.  We, the members, are the reason we have observing Star Parties, and they are great occasions to get familiar with observing.  We do have 10" Dobsonian telescopes

available at the Dark Site for your use. There will also 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 via the NHAC email.  It is only necessary for any 1 member to request access-- Access approved for any of us is access approved for all of us.


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.

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

Public Night will be on Friday,

October 5, 2018


Sunset will be at  7:02 P.M.  The moon will not rise until after midnight and will be no factor.


Doors will be open by about 6:45 P.M. and remain open to the public until 10:00.


These Public Nights are a great 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 6" Takahashi refractor, a 16" Meade Schmidt-Cassegrain, and a 20" Plane Wave telescope.  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 the sky 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.  This may be an excellent chance to see Mars in a big scope!


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 Insperity Observatory is at:

Jack Fields Elementary School

2505 S. Houston Ave.

Humble, TX 77396


The Observatory Phone number is 281-641-STAR.
