A planisphere and a pair of binoculars are all you need to get started with stargazing.
The Seven Sisters star cluster, a.k.a. Pleiades, is an easily found star group in the winter sky. It is located in the Taurus Constellation and the three stars that make up Orion’s belt almost point to it. With just a little light pollution though, this can be a difficult group of stars to see, and without an optical aid, the seventh star is seldom seen.
When talking about night skies, “optical aid” usually conjures up images of massive and expensive telescopes. However, Kitt Peak National Observatory issued us each an ordinary pair of binoculars at a recent star party and I was surprised at how much they helped. For instance, instead of a fuzzy cluster, Pleiades became a group of far more than seven stars, all clearly visible.
Several other tools will help you enjoy the night sky. The first is a headlamp or flashlight with a red lens. Why the red light? The rhodopsin in the rods of our eyes doesn’t flush out in reaction to red light like it does to white light. You can preserve your night vision and still see to move around safely.
An inexpensive planisphere is a must have. This is really a fancy name for a star chart or sky map. Since the night sky constellations you see appear to move as the earth turns (that is why a long exposure photograph of the stars shows lines or arcs instead of pinpoints) and as seasons progress, a planisphere has a couple of unique features. The first is that it is adjustable for the date and the time of night. By aligning the date and the time together, the planisphere shows exactly where everything is at that moment in time.
The other feature is that the sky on the planisphere rotates around the grommet in the exact center representing the North Star. The North Star is the only star in this hemisphere that does not appear to move and that is why it has been so important to navigation for millennia.
One other thing to know about planispheres is that they come calibrated to specific latitudes. The 45th North latitude circles the globe just south of Salmon, Idaho so pay attention to which planisphere you are buying.
If you have a spotting scope that you use for wildlife, it can be a handy tool for astronomy. The challenge is in finding what you want to look at in the first place. When viewed on a dark night through optics, the night sky has far more stars than you can imagine and pinpointing the right one can be problematic.
Astronomy laser pointers are the final tool. They cost from $20-50, use a green beam and are in the 503nm beam-width range (these are NOT toys! Keep away from children and pets!). They make it easy to point out stars and constellations to others. Strap one alongside your spotting scope and you have a simple way to roughly align it with the stars you want to see.
People are perhaps the best “tool” for learning the night sky. Consider contacting the Idaho Falls Astronomical Society at: http://www.ifastro.org/ or visiting a planetarium. Both BYU-Idaho and The College of Southern Idaho have telescopes and planetariums free or at nominal cost to the public.
To induce you to look at the stars, I will leave you with one teaser: guess which major car company takes its logo from the Pleiades star cluster. Hint: it is also named for the cluster (in Japanese) and the answer is hidden in my bio below.

TAX DAY is coming! Here is a chance to do something good with a bit of your tax return and make the day less painful.
Donate part of your tax return to support wildlife in Idaho!
On the second page of the Idaho Individual Tax form 40 you have the opportunity to donate to the “Nongame Wildlife Conservation Fund”.
Check-off this box on your next return or ask your tax preparer to mark the Nongame check-off on your behalf.
If you are not from Idaho, check with your own state wildlife agency about how you can help. Many states have a similar program.
Wildlife License Plates
Idaho Wildlife license plates provide essential funding that benefits the great diversity of native plants and wildlife that are not hunted, fished or trapped—over 10,000 species or 98% of Idaho’s species diversity. Game species that share the same habitats (such as elk, deer, antelope, sage-grouse, salmon, trout) also benefit from these specialty plates.
No state tax dollars are provided for wildlife diversity, conservation education and recreation programs. Neither are any revenues from the sale of hunting or fishing licenses spent on nongame species. Instead, these species depend on direct donations, federal grants, fundraising initiatives—and the Idaho Wildlife license plates.
Both my vehicles have Bluebird Plates. I prefer the bluebird because the nongame program gets 70 percent of the money from bluebird plates, but only 60 percent of the money from elk and trout plates - 10 percent of the money from elk plates supports wildlife disease monitoring and testing programs (to benefit the livestock industry) and 10 percent from cutthroat plates supports non-motorized boat access.
Incidentally, in 2014, the Idaho Legislature denied the Department of Fish and Game the ability to add new plates or even to change the name of the elk and cutthroat plates (very specific) to wildlife and fish plates, a move that would have allowed for changing images occasionally and generating more revenue. It would seem that they believe that we Idahoans don't want a well funded wildlife program. Go figure.
"WOW. What a phenomenal piece you wrote. You are amazing." Jennifer Jackson
That is embarrassing but actually a fairly typical response to my nature essays. Since The Best of Nature is created from the very best of 16 years of these nature essays published weekly in the Idaho Falls Post Register (online readership 70,000), it is a fine read. It covers a wide variety of topics including humorous glimpses of nature, philosophy, natural history, and conservation. Readers praise the style, breadth of subject matter and my ability to communicate complex and emotional topics in a relaxed and understandable manner.
Everyone can find something to love in this book. From teenagers to octogenarians, from the coffee shop to the school room, these nature essays are widely read and enjoyed.
Some of the essays here are my personal favorites, others seemed to strike a chord with readers. Most have an important message or lesson that will resonate with you. They are written with a goal to simultaneously entertain and educate about the wonderful workings of nature. Some will make you laugh out loud and others will bring a tear to the eye and warm your heart.
"You hit a home run with your article on, Big Questions in Nature. It should be required reading for everyone who has lost touch with nature...great job!" Joe Chapman
"We enjoyed your column, Bloom Where Planted. Some of the best writing yet. The Post Register is fortunate to have your weekly columns." Lou Griffin.
