Stars and Mars


Daylight veils and night-time reveals the most majestic sight of the planet Mars, like a huge red star, rising in the east soon after dark, dominating the sky. It's at its closest to the Sun right now, meaning that it's at its closest to us, and on the 16th was precisely aligned with the Earth and Sun. Oh! I tried so hard to get a photo showing how I felt when this planet appeared in the eastern windows each night, persisting, as if it wanted something. I'll give it! (This is the best my camera could do; there's a more awesome photo here.)

Dominating the southern sky not long ago were the two brilliant planets Jupiter and Saturn, so bright in the bedroom window that after settling in I got back up and went out to look at them. They're headed west, sinking soon after sunset. On December 21 (winter solstice!), look low in the southwest at sunset, and Jupiter and Saturn will be in a rare conjunction at 0 degrees of the sign Aquarius. This is also called "the Great Conjunction" and occurs every 19.6 years. Astronomers say that the star the Magi noticed and followed was a Jupiter-Saturn conjunction.

This 2020 at least the planets are with us and want to entertain us!

Everybody Knows This, Except You

In life I've met with many things everyone else knew but me: how to pronounce "derriere" and "decollete"; that people are born naked (the shock!); that bottled mayonnaise and salad dressing differ while looking the same; how to light matches; that not all plants are perennial; that screws tighten when turned rightward; that salaries are negotiable and the first offer is a lowball; that canned tuna must be drained (we never ate canned tuna; the kids I babysat showed me how); how to tie shoelaces without making two loops and crossing them. From age 6 to 55 I walked around with shoelaces tied "backwards" and ignorance was bliss.

That applies to my first telescope lesson. The eyepieces ordered, of good quality and standard size, were a bit too big to fit in the tube you put your eye to. I tried everything. I even unscrewed one lens from its base and dropped it into the barrel, and oops, down the tube it went, requiring me to strong-arm the 22-pound telescope upside down to get it out.

I would not give up on my free telescope with useless new $20 eyepieces; I just wouldn't! After a long search I learned a fact apparently everyone knows, so basic it's not even listed in specifications: older cheaper telescopes use eyepieces .965 [inches] across, and today's standard measures 1.25."

.965s are so obsolete that adapters are scarce, but I found and ordered one. From now on, though, I know what to tell anyone who fosters or adopts a homeless telescope.

The Homeless Telescope

We'd not seen each other in 10 years, but a Facebook friend, a city resident, knew I liked stars and one day messaged and asked if I wanted a telescope. I have always wanted a telescope. We met and placed the entire assembly in my car's trunk because neither of us knew how to separate the telescope from the tripod -- and if we did we might not know enough to reassemble it.

It's a 114mm Polaris by Meade reflector telescope, and somebody bought it and never used it and gave it to my Facebook friend who kept it in his garage hoping to use it but never did. It looked quite too noble to be homeless.

Before even daring to clean the dust from it I'm trying to learn whether it's salvageable. First, telescopes shouldn't be left outside, especially not in garages that can get very hot. Only my porch or my heart have any room. I figured if it's been garaged for a couple of years staying on the porch awhile wouldn't do much further harm. The buyers' reviews said it's a beginner's telescope but good quality for the price, about $150 new. The knob sticking out on the right is a counterweight.

Looking down into the eyescope I discovered it lacks an eyepiece. New telescopes come with a set of 3 eyepieces, but this model of Polaris had cheap ones I can replace with better-quality eyepieces for about $20. The eyepieces are everything. The telescope's focus is permanently set to "infinity." That I liked. There is at least one scientific-looking ring marked in increments, in white paint, 0-360.

I also learned you can buy new telescopes controllable with your phone. Using an app, enter the desired astral object and the telescope will find it automatically. But one cannot use those 'scopes manually. Without Wi-Fi there'd be no stargazing.

Ahead: more learning, and maybe some joy. If I can restore and master this one, I can master a finer one.

Harvest Moon

Came home from a skirt-and-high-heels event dragging a huge bag of apples a friend harvested from his trees and gave me. Saw the rising full moon, said, "That's cool!" and grabbed camera and tripod and ran outside and worked until I got what I saw. The moon that's closest to the Fall Equinox is called the "Harvest Moon". This one's in the sign of Aries. Because it's the second full moon of the month for most of us, some people say it's a "blue moon." According to Wikipedia they aren't technically right, but let's pretend they are.

Ring Around the Moon Tonight

Usually the atmosphere is full of ice crystals, but at times some do line up to party, and moonlight reflects off their hexagonal bodies at a 22-degree angle, causing a 22-degrees-diameter iridescent ring around the moon. Majestic!! Rare here in Missouri, but it happened Tonight, with a first-quarter moon. When clouds began to drift in, the ring vanished. Why do I never think about the beauty of ice rings until I see one? It's always a surprise gift! Hardy migrating birds such as flickers and sapsuckers may appear any day now.
