Music to Stargaze By

By: Sherry Rashad

My family’s (even though I seem to be the only one using it) 250 US dollar – MSRP bought back in 1996 – Tasco refractor did prove useful after being purchased timely enough to witness a couple of notable comets. Even though Hale-Bopp is now a distant memory and I have to drive – no plan a trip like it involves major Hohmann transfers that would envy Isaac Newton – due to our increasing local urban light pollution just to secure a better vantage of the universe.

It’s been a well-known anecdotal fact that tenured professional astronomers tend to gravitate toward Classical Music like Bach, Beethoven, Mozart, etc. But what about the background music that they listen to while doing old school stargazing – i.e. stargazing with a telescope that they can lift alone in some spot beyond the scourge of urban light pollution?

As an “experienced” amateur astronomer – a contradiction in terms if ever – most “man-portable” astronomical telescopes priced under 5,000 US dollars tend to be very sensitive to vibration. I experienced this first hand when I observed the Hale-Bopp comet back in 1997 while listening to Iron Maiden’s “Fear of the Dark” to a portable boombox. Mind you, portable low-rent boomboxes are notorious for screwing up the sound quality of properly recorded acoustic Classical Music. Since “good quality man-portable hi-fi that pass muster to my finicky ears” are yet to be invented, its low-rent boomboxes for background music for now.

Not surprisingly, my Heavy Metal -”elevator music” produced enough vibration to make the image on my astronomical telescope’s eyepiece a very curious psychedelic event. The Hale-Bopp comet, or the planet Saturn, or any celestial body that I happen to look at now looks like that alien probe shown on the TV series Threshold as it quantum-tunnels itself from it’s homeworld into our planet. Or is the proper term super-stringed itself via a higher dimensional plane into our planet after instantaneously traversing billions of miles of interstellar space.

When you magnify anything greater than 30 times, vibration can be a serious issue. Adapting my trusty astronomical telescope for ad-hoc use on distant sailing yachts, even a cat gingerly passing a meter away is enough to make the observed image on my telescopes eyepiece shake like I’m having an acid flashback. Even if I was born in 1972! Way after the LSD craze - or is it the ease of availability.

Basing on my firsthand experience, I now wonder if tenured professional astronomers who are being assigned to man telescopes with mirrors over a meter in diameter and who manage to smuggle a “decent” hi-fi into their workplace. Like a Quad II amplifier, Thorens turntable, and a pair of Quad ESL 63 electrostatic speakers plus the de rigueur subwoofer – might be compromising their “observations” by excessive “musical vibrations”. Listening to Bach played on the Saint Säens organ might seem like an excessive extravagance in my point of view. I just even recently found out that even string quartets playing genteel minuets are enough to produce vibrations visible on your telescope’s eyepiece to make stargazing into a pseudo acid flashback.

Now I get it why Hollywood just started to recently “glamorize” US Army and USMC snipers with a big-bore anti-materiel rifle hitting targets over 10,000 feet away equipped with just a 22 power scope. When you are shaking like your average crystal meth addict, it’s a task that’s impossible as hell. With sonic vibration such a big issue, will stargazing cease to be a multi-sensory experience of staring at distant celestial object while listening to a Bach organ cantata or The Gathering’s “How to Measure a Planet”? I’m not asking any other soul to comply with me. I’m just saying that given the sensitivity of the kit that we have – and it’s getting cheaper by the way – you can’t just plunk in any CD in your boombox. And not be expecting that the “musical vibrations” to turn a120-times magnified image of the planet Saturn into a “psychedelic experience”.

It can be a problem for us who can't afford a tripod 3 times more expensive that the astronomical telescope that we originally bought. There are a number of books about building your own astronomical telescope but none so far are about building better tripods for them. I'm currently using a tripod from a Soviet-era heavy machine gun tripod. And even with this "desperate measure" vibration can be a problem in high-traffic areas like cobble stone footpaths. Maybe it's just me , but when I stargaze, I prefer to play music only in my head. It can be as loud as Mahler's Eighth - or the Pratt and Whitney F100 afterburning turbofan voice of God and Her infinite wisdom loudness of The Gathering's How to Measure a Planet all 28 minutes of it - without "shattering" the optics of my scope.

Are we in a situation that allowed Paul Krugman to win the 2008 Nobel Prize for Economics? I mean we both live in a country where a 50 caliber Browning Machine Gun rounds are way, way more plentiful than Western Electric 300B vacuum tubes. Never mind reasonably-priced accessories for "portable" astronomical telescopes.

Sherry. Would you like to show picture taken by your Tasco Telescope?
