The O-TEAM: A Thousand and One Nights

(Late - very, very late; one night in 1989...)

As one-third of that, one-time, infamous trio of hard-core, dedicated, 'back-woods', 'MacGyver'-ish, observational astronomers: the 'O-Team' - Mike Petrasko, Muir Evenden, and myself, who's late-night and, sometimes, 'deep-freeze' telescopic adventures, back around 1989 (typically, in below-freezing temps) -- I would never, ever have believed that one day - our telescopes would be able to, practically, "take us by the hand", and give us a detailed, orated tour of the night sky - all by their artificially intelligent selves. Nope - that's the kind of thing that only happened in sci-fi films...

Moreover, how could any of us possibly have imagined, that, variable stars - those, peculiar stellar anomalies who are light-output, vary over periods of time, from about a few hours to several days, should turn out to be *variable* - because there were planets getting in the way! - by crossing the faces of those stars (as seen from our perspective)...of all things!!

Many times, over the "O-Team years", some 30-something years ago, I had made painstaking efforts at trying to capture such things, as, the North America nebula, or the galactic core in Sagittarius, on film, using a piggy-backed, 35mm SLR, loaded with Fujichrome 200, acetate slide-film. With a lot of patience, and, even more, practice, something like this could be gotten - in as short a span as 45 minutes - using the telescope, as a guide scope, during the exposure. I could never have imagined (not even in any of my wilder dreams) that, film - the conventional platform for photography, since its invention - the century, before last - would soon be replaced with the microchip capable of generating an equivalent image in 10-20 seconds - un-guided!!

Unfortunately: I have missed out - entirely - on the GOTO, computerized, Dobsonian-mounted telescope revolution: that is - the kind of amateur astronomical telescopes that are capable of re-positioning themselves, by 'slewing' across the sky, via, computer-controlled, stepped servo-motors - to any celestial object in the heavens, using the celestial coordinates, right-ascension, and declination - by converting them into their alt-azimuth counterparts - all on command!"....

I've never used one. In fact - I've never even SEEN one (at least, not 'in person').

No. My active days (or rather, nights) as an observational astronomer with the O-Team were the kind, where, in the cold months, you got dressed for the weather using three layers of outer garments, three layers of warm socks for your feet - wrapped over, with plastic trash bags to keep the warmth in under your boots - and, at least, one wool cap and a pair of mittens (mittens hold in heat better than gloves).

If you didn't look like you were ready to start training attack-dogs - you were missing some clothing.

When you were finally ready - you disassembled your scope and packed it into the back seat, trunk, or bed of your vehicle, and - if you could, still, just slide into the front seat - you were ready to drive yourself, along with your gear, to one of your, very, best-kept secrets: a chosen, dark, secluded and, preferably, isolated observing site! (We actually had two sites that we frequented, but, one, in particular, was, by far, our preferred nocturnal "delinquency". You see: on many, many starry nights, you could find me, and my telescope (well - and, my truck!), and Mike and Muir, and their vehicles, perched on one of the fairways at the Woods Hole Country Club's plush, green carpet, of highly-manicured grass. To say that we were obsessed - well, that would be a really, really accurate statement...

On any, given, clear night, we would abandon the warm, blissful comfort of our cozy beds at around 12:00 midnight, and drive out to our, apparently, God-given observing station; or any party-cloudy night, for that matter - just in case. And if you've never seen the unlikely, ominous sight of a silhouetted Volvo, parked in the middle of a golf course in the middle of the night - before, well, you just haven't lived!

From our perspective, golf courses were built, and designed, for astronomers. They offer wide expanses of sky, and - serendipitously - are covered with a durable, and, surprisingly well-kept swath of grass - which, seems to run on, in all directions, forever! Now, what philanthropic soul had done this great service for science? (I never did believe in the rumors, that, they also used these green havens, for other, unimportant 'sporting activities', as well).

Here's how it usually went...

After arriving at the golf course, and, having driven, up, onto the fairway, you set up your scope and connected it, via, mini-jumper cables w/alligator-clips, to your vehicle's battery. This was to run the electro-mechanical clock-drives, that, slowly moved the scope, in synch with Earth's rotation, across the sky to follow the particular celestial object you were observing. Muir used an 8-inch Celestron Schmidt-Cassegrain. Mike had an Edmund Scientific, 4.25-inch AstroScan, and I used an 8-inch Meade Newtonian reflector.

The next step was to set up the card table and lay everything out on it: a very good, laminated star atlas with reticle templates, a red-filtered, military-style elbow flashlight, eyepieces w/case, pocket shortwave radio, tuned to WWV (for timing anything you wanted to time) along with, Mrs. Holmes' home-made brownies, if you were fortunate enough - and pray that you didn't completely drain your vehicle's battery, by dawn. (There were actually statements, like: "Oh, well; if my battery dies, I'll just call a tow-truck in the morning.", made, frequently...who cared?!)

Now, all this was usually set up near the frozen, ice-covered, first-hole putting-green of the WHGC - regardless of winter, or its threat of frostbite, or - of the threat of getting booted off the course by the local law enforcement. You see, we once (once?!) had a brief encounter with a police officer, who, was out on his rounds and, spotting, three, parked automobiles - in the middle of a golf course - had decided to drop by our private, highly-manicured observatory.

Having noted our three, rather large-ish, optical instruments, tables, chairs, ladders, and vehicles - electrical connections and all - the officer, slowly and cautiously approach our bunker, and asked, "What kinds of weapons", we were using to, obviously, protect ourselves against, the potential, horrors of the night sky. Naturally, we all-too-excitedly broke into a rather lengthy discourse about the myriad wonders - galaxies, nebulosities, etc., that we had seen that night, and offered him a view for himself; with such fervor and passion (which, he, apparently didn't share with us), that, he probably just couldn't wait to escape the bizarre situation.

Over time, they eventually learned to ignore us, entirely and, for the most part, we continued to have the WHGC, all to ourselves for our continuing, awesome onslaught of the universe, at large.

And that's how those days went.

But times have changed dramatically. Today, all this is done, remotely, with a laptop, or tablet, or even, smartphone - right from the comfort of your own bed!!

What will the next, 30-something years in amateur astronomy bring?.....

Though I've never played a game of golf in my life - I used to frequent the Woods Hole Golf Club's course, at Woods Hole, Mass. - in the middle of the night, that is. You see, I'm an astronomer/astrobiologist.

On any given clear night, fellow astronomer Mike Petrasko, and I, used to drive our car and light pickup, equipped with my 8-inch, and Mike's 6-inch, 50-inch long, 70-inch high Newtonian reflector telescopes, up onto a fairway at at the golf course, in Woods Hole, to about the course's center.

There, we set up the telescopes and connected their motorized clock-drives, to our vehicle batteries, with cables and alligator clips; this was necessary so that, as the Earth rotates during the night - and the stars drift slowly across the sky, the telescopes, when aimed at an object, could counter that motion and follow along, defeating any tendency for the object to drift, in the telescope's field of view.

During the winter months, we'd usually arrive at the golf course just before midnight, set up the equipment and prepare to spend several hours in sub-freezing temperatures - many times, in the single digits. We'd break down the equipment and leave just after dawn. This happened three or four nights a week - regardless of our regular work schedules, of course.

We chose that particular observing site because the sky there is relatively dark, free of light pollution, to the north, and absolutely black in the south, over Vineyard Sound. Mike and I had been monitoring a list of galaxies, for possible, extra-galactic, supernovae outbursts.

Extragalactic supernovae are exploding stars, located in galaxies beyond our own Milky Way galaxy, the closest being several thousand light-years away. These outbursts occur, on average, only once every hundred years, or so, in any given galaxy - including our Milky Way. We actually discovered one, one morning, in February of 1989. It is known, today, as SN1989b and is located in the spiral galaxy, M66, in the constellation Leo, the lion. I remember that night very well... - it was 4°F!

One morning, around 4:00am, a local police officer drove up onto the course in his cruiser, with spotlights glaring, and parked next to my truck. In a mock tone of extreme concern, he asked me, what kind of weapon it was that I was using, and what it was pointed at! I told him that, that was highly-classified information and that I could not give him a meaningful answer. He enjoyed the comeback.

After we had explained that we were astronomers, with the SUNSEARCH program, of the Harvard-Smithsonian Observatory in Cambridge, and that the unusual looking instruments in question were astronomical telescopes, he pointed out that we were not supposed to be there, without express permission from the owner; we could only agree. But, he said, since our activity was benign - and possibly even useful, and since the ground was frozen solid (being February, our tires didn't mess with them, normally, immaculate grass) - that it would be OK, though, he suggested we try golfing there some time, instead.

Some of the finest - and loneliest - hours of my life were spent on that golf course, scanning the universe with my telescope and witnessing, first-hand, many of its mysteries, free of charge. It is where, one night, for the first time, with the use of my Skalnate-Pleso Observatory star atlas, that I had experienced a keen awareness of my bearings and my relative position on the Earth, and its position within the solar system, and the solar system's position within the Milky Way galaxy. At that moment, I simply felt like, for the first time, I knew exactly where I was.

It was there, throughout the year, that I did several Mars and Saturn observing sessions, and was witness to a global sandstorm, one night on the red planet. I also made note of any changes, over time, in growth or shrinkage in Mars' south polar ice cap, as Mars progressed through its seasons throughout the Martian year. I've seen Saturn's rings, both in an edge-on aspect and wide open. The interval between those two extremes is about three decades long. Yup, I've been around folks.

Maybe, someday, I'll take that officer's suggestion and play a game of golf there... after I learn how to play, of course... “Fore!”
