The Hale-Bopp Experience

By: Sherry Rashad


One of my childhood dream jobs was being an old school astronomer, the one that peers into the eyepiece of a single-person portable astronomical telescope out at night. Unfortunately, tenured astronomy professors today sit in front of a computer monitor looking as images delivered by their CCD cameras stuck to the end of their astronomical telescopes. Lucky ones even have access to live feed Hubble Space Telescope downloads. But I’ll probably never forget my Hale-Bopp comet experience back in 1997, especially since I was lucky enough to have purchased a starter astronomical telescope a few months before the Hale-Bopp comet became headline news.

Maybe it was the “mild guilt” of not having an astronomical telescope back in July 16, 1994 when the comet Shoemaker-Levy 9 crashed into Jupiter. Or the appearance of the extremely long tailed "Great Comet of 1996" a.k.a. Hyakutake Comet back in 1996. Though spectacularly visible to naked eye observation because it's the closest comet to approach Earth in the past 200 years or so. Comet Hyakutake really compelled me into purchasing a modest starter kit capable of magnifying up to 300 times and cost 500 US dollars or less.

Eventually, I did purchase a Hong Kong made Tasco model which got good reviews from Sky and Telescope magazine on refractors costing below 300 US dollars back in 1996. And my modest but sensible investment really did pay off when the comet Hale-Bopp arrived back in 1997. This comet was an oddity, originating in the Oort Cloud region of our Solar System with a period of 2,380 years. The Hale-Bopp comet will next be seen in the year 4377.

Unlike other fair-weather amateur astronomers, my astronomical telescope hasn’t retired into some storage space gathering dust unlike most of my fellow Hale-Bopp comet watchers. Though I have to drive three ours or so into the country to use my astronomical telescope in it’s intended purpose due to increasing levels of light pollution in urban areas. Despite of the dearth of comets visiting the inner Solar System in the 21st Century, our Solar System’s two closest gas giants – namely the planets Jupiter and Saturn – still manage to attract my interest.

This - I mean amateur astronomy - is probably the only hobby were age has a definite advantage. Although I was only 14 back then, I did saw first hand the 1986 appearance of Halley's Comet despite being labeled as a "visual dissapointment". The best - so far - was probably Hyakutake and Hale-Bopp. I might live long enough to see the Halley's Comet return . I'll be 90 by then. Given the advances in Healthcare etc...

When it comes to astronomy - even being an amateur astronomer with no university tenure - age does an advantage. I was probably still 5 or something when Hyakutake and Hale-Bopp comets came. Though I might live to see the return of Halley's Comet if President-elect Obama manages to fulfil even half of his campaign promises. I can't help it, I'm an Obama-maniac.
Have you ever come across the Arend-Roland comet? Many astronomers say that this comet will probably never return since it was travelling so fast that it escaped from our Solar System. I've only seen it on photos, the comet hs this weird fan-shaped "antitail" or something.

I'm one of those "fortunate ones" who have the higher cognitive function to give a damn about the appearance of comet Hale-Bopp back in 1997. The "Great Comet of 1997" also made the constellation of Cassiopea popular because "she" was frequently used as a referrence point in directing amateur astronomers to the commet Hale-Bopp.

When it comes to watching comets, age definitely has an advantage. Sadly, the Arend-Roland Comet came about 15 or so years before I was born. And judging by the comet's observed path. it might never return.
The "W" of the constellation Cassiopea was frequently mentioned back in 1997 as a reference point / guide for Hale-Bopp Comet observations. Given that "man-portable" astronomical telescopes have a narrow field.
