Star Parties This Fall 2017

As the Autumnal Equinox passes us by the nights start growing longer and cooler in this part of the world. It’s the perfect time for a star party. I thought I would offer up some star parties that you’ll want to add to your calendar. Star parties are great opportunities to get out under the night sky, visit with like minded folks and peek through an assortment of telescopes.  This can be very rewarding especially if you are thinking about buying a telescope.

The events listed below are within an hour or so drive, or closer, from the DFW area that I have  been to in the past and have found to be very enjoyable. Some have presentations at the beginning of the evening explaining basic astronomy concepts and discussing what can be seen in the sky and telescope that evening. Don’t miss this presentation as it will provide important info and guidelines for the evening as well as help set the tone and your expectations. Also, sometimes there are astronomy related giveaways or door prizes that you can get in on too.

Total Solar Eclipse From Hopkinsville, KY

What a great adventure to Tennessee and Kentucky to see the Great American Total Solar Eclipse. I viewed the celestial show from Hopkinsville, KY with several coworkers who also made the long drive.

TSE 08212017 – The moment before totality

The “solar funnel” (solar projection cone) seen below that I had made a few months back in preparation for this eclipse was a huge hit with eclipse chasers! I received many compliments and plenty of return visitors to check the progress of the partial phase.

 You can view the HD video I shot before, during and after totality below. Totality begins at about 10 minutes into the video.

You can find many more of my eclipse pictures as well as pictures of the telescopes and fellow eclipse chasers on my Total Solar Eclipse – 8/21/2017 page that I’ve added to this site.

Great American Total Solar Eclipse

We are now in the home stretch for what is being called the Great American Total Solar Eclipse. Not in 99 years has a total solar eclipse made its way across the continental U.S. and surely it will be one of the most observed total solar eclipses in history.

Total Solar Eclipse – February 26, 1998

The last total solar eclipse that I was present for was on February 26, 1998. Nineteen years ago my wife and I took a 7 day cruise and saw the eclipse on board the ship off the coast of Aruba in the Caribbean. Seeing the eclipse at sea was a very special treat indeed. With a flat horizon for 360 degrees it’s easier to see the moon’s shadow build on the horizon, speed toward you at almost frightening speed, over take you and speed away. I vividly recall the emotional response it generated in me and all who were there to see it. No pictures or movies can accurately reproduce this type of event. It simply must be experienced. I learned first hand that day why and how some many people become eclipse chasers. Sounds odd to those who don’t give a second thought about astronomical events but rest assured the experience drives people to see it over and over again. Kind of like a roller coaster junkie or sky diver who lives for the thrill and once seen longs for the next high from his or her obsession.

Solar Funnel Project

5″ Meade Newtonian reflector with solar funnel.

Doing star parties over the years I have witnessed long lines of party-goers queued up to take a peak through my telescope. I’ve found this to be the perfect time to talk to folks about what’s being looked at in the telescope. I like to throw out some fun facts and this always spawns more questions and curiosity in the gathered group. Talking to adults and kids about the night sky is one of the greatest aspects of doing star parties.

There is a limit to how many people can look through the scope at any given time, put simply it’s one at a time.  But when I saw this neat gadget called a “solar funnel” I immediately knew it would be great at eclipses to show participants the partial phases and better yet it could do this via projection so many people close by can view the eclipse at once.

CHAOS OR COSMOS IN THE SHADOW OF THE MOON

The lure is there. Friends and family not going to the eclipse are quick to say “be sure and take some good pictures!” You of course were already planning on taking pictures but now there is added pressure to get it done, and those shots had better look great! The last thing you want to do is have to show them some blurry, unfocused, dark, eclipse pictures.

Partial Solar Eclipse 6/10/02

Recording a total solar eclipse on film, digitally or using a video camera can quickly become a huge task that monopolizes your time. The logistics of getting all your equipment to your observation site and setting up in a timely manner alone introduces stresses that factor into your experience.  All of this adds up and can in some cases ruin both you and your family’s eclipse experience.

Here are some suggestions for helping to ease the stress level and to allow you to get the shots you want and need all the while enjoying the eclipse. But that can’t be done, can it? Sure it can.

Light, Distance and Time Travel

How far can we see into space? A very long way indeed. But not only are we seeing objects that are far away we are also seeing them as they existed (past tense). Why? Because as much as we would like to think light is instantaneous it actually travels at a measured or finite speed.

How fast is it? Light travels at 186,282 miles per second or roughly 300 million meters per second. Pretty darn fast but when you start talking astronomical distances the speed of light becomes apparent. Once you know the distance to an object you can then calculate how long it takes light to reach it.

1st Quarter Moon

The light reflected from the Moon takes 1.255 seconds to reach us here on Earth. Light emitted from the Sun takes over 8 minutes to get to us. And so on. The most distant galaxies in the Hubble Ultra Deep Field image are 13 billion light-years away.

Updates to the Blog Site

I’ve been busy working on the blog site and have added a number of things that should be useful to visitors. Here’s the run down.

After having been removed several months ago due to issues it had with the WordPress site theme, the Events Calendar makes its return.  You can now check on specific dates for astronomical events, star parties and much more on the calendar or give a glance at the “upcoming events” in the right-hand column on the home page. The calendar still needs to have events added but April and May are done.

Crepuscular Rays

Crepuscular rays over the rooftop.

Crepuscular rays or Sun rays are rays of sunlight that appear to radiate from the point in the sky where the sun is located. These rays, which stream through gaps in clouds or between other objects, are columns of sunlit air. Despite seeming to converge at a point, the rays are in fact near-parallel shafts of sunlight, and their apparent convergence is a perspective effect (similar, for example, to the way that parallel railway lines seem to converge at a point in the distance).

Comet 45P/Honda-Mrkos-Pajdusakova

As 2016 comes to a close corks will be popping and fireworks firing to be sure. But make sure in all the excitement you don’t miss the celestial fireworks!

There will be the opportunity for you to see periodic Comet 45P/Honda-Mrkos-Pajdusakova in the constellation Capricornus.  This comet has an orbital period of just 5.25 years that takes out to Jupiter’s orbit before plunging back toward the Sun.

The best time to view will be just after sunset on new years eve, December 31, 2016. The south-western sky will be filled with other great objects for you to observe besides the comet including the Moon, Venus, Mars and Neptune.

The sky chart above shows Comet 45P at about 21 degrees above the horizon and roughly 5 degrees away from the Moon. This will make for great viewing with binoculars or a telescope.

In early February this comet will pass within 0.1 AU of the earth. It is predicted to reach maximum brightness of magnitude ~7 in early January.

19th Annual North Texas Skywatch Star Party

North TX Sky Watch Star PartyThe 19th Annual North Texas Skywatch Star Party will be held at Lake Mineral Wells State Park on Saturday, October 22, 2016.

The park is located 50 miles west of Fort Worth.  This very popular family friendly star party (average attendance of 200) is hosted by Lake Mineral Wells State Park and Dr. Mike Hibbs of Tarleton State University.

The North Texas Skywatch Star Party will start at 7:00 PM and last as long as observers want to stay up. The intent is to give the residence of the North Texas a nearby meeting place and dark sky location to get together. “I hope that all of those with telescopes can stay and share views through their telescopes, or knowledge of astronomy, to those wanting a chance to learn and see for the first time.” The only cost is the normal State Park admission. You will be able to camp out for the night if you want. Come early and enjoy the park and have a cookout.  Lake Mineral Wells State Park is about 50 miles west of Fort Worth off of HWY 180.  Contact the Park for the entrance and camping fees and reservations.
