First Light

Sometimes I really hate being right.

Last week, I predicted that it would be a string of cloudy nights as soon as my new Celestron telescope arrived. Sure enough, the skies were blanketed with thick clouds for days. Although the downtime gave me a chance to study the telescope manual and familiarize myself with how to plug all the pieces together, it was like getting water skis for Christmas.

The kicker for the week was the approach of one of the worst October snowstorms to hit New England in decades. This sort of thing never happens - - until someone orders a new telescope, of course.

Two waves of  storms were supposed to pummel the East coast, and astronomy seemed out of the question. However, there was one ray of hope in the forecast: between the two storms was a brief respite near midnight. The sky cover was supposed to thin to 10% overcast, so I took a chance and drove the telescope north to Captain Girlfriend's house.

The Captain's backyard is ideal for sky watching. Except for an annoying clump of pine trees to the north, the yard has a near perfect view of a dark, rural sky. Jupiter, due at opposition that same night, would be high in the moonless sky - - as long as the forecast held up.

This would be my first attempt at letting the telescope's auto-orientation do its business. According to the instructions, all I had to do was point the scope at a planet (say, Jupiter) and the telescope would figure out where the rest of the sky was. It seemed a bit Buck Rogerish, but I hoped it would work like it said in the manuals.

True to the Weather Channel's forecast, the clouds began to clear at 11pm. I stepped out into the dark, lugging a 50-lb telescope down The Captain's back stairs. As I set the telescope down on the driveway, Jupiter popped out from behind the passing clouds. It was BRIGHT - - at opposition, I think it was magnitude -2.2. The alignment on the finder scope was a snap - - the scope had a little red LED dot that covered Jupiter perfectly. I fired up the telescope's tracking computer, told it the scope was looking at Jupiter, and then screwed in a 32mm objective lens to get a close-in view.

This is what I saw through the lens:


Okay, I didn't have the band Train playing through the telescope, but that's pretty close to the view through the Celestron. Amazing. "I Eat Green Carrots" flashed through my head as I was trying to name the four Galilean moons in my eyepiece. It was like I was 11 years old again, looking through my Monolux refractor scope.

Then, the clouds moved in, and the second storm commenced. I packed up the telescope and loaded it back in my pickup truck. The clouds and snow continued through the end of the week.

Now, the telescope and I are back home, and the weather forecast is predicting clear skies tonight. Can't wait to see what this telescope can do without clouds in the way.

Steve Jobs

I've never purchased an Apple product. My cellphone is a Droid, my computers are Windows-based or Ubuntu machines built by HP, and my music isn't stored in an i-anything.

Yet, Apple has been a part of my life since the late 70's. I sold TRS-80 computers for Radio Shack, and frequently heard comparisons to Apple's 6502 microprocessor machine.  Their systems always seemed more robust and had many more third-party hardware and software companies than the Radio Shack line. The few people I knew back then who owned Apple machines seemed to be even more enthusiastic about their machines than the TRS-80 owners.

Although I've never purchased an Apple computer, I did own one for about a year. It was a Lisa, the failed precursor to the Macintosh. A friend of Michelle's had bought several then-new Macs for his office and asked me if I'd like his old Lisa. I took it home and fired it up. It was a pretty amazing computer, considering it came out about the same time as the IBM PC-XT. The icon-based screens, reflecting Steve Jobs' successful co-opting of the Xerox Palo Alto GUI, was years beyond anything on other manufacturers' machines. Windows --- the kind of GUI experience already present in the Lisa -- wouldn't arrive until almost a decade later.

Steve Jobs didn't invent all of this, but he brought together the kinds of minds who could build this for the world. Jobs was a promoter even more than he was an inventor. He could sell his vision to others, and show people how wonderful, how simple, and how smart computers could be. In short, Steve Jobs made the future happen - - even for those of us who never bought his products.

A lot of obituaries this evening are making comparisons between Jobs and Thomas Edison, but I think there's a closer comparison between Jobs and Wernher von Braun. Edison focused on the present, but von Braun, and Jobs, sold us on the future - - a future that few could ever imagine happening.

RIP, Steve.
