Newsweek's *Tip Sheet* section had an article, "Scoping Out the
Stars," on page 56 of the July 28, 2003 issue that caught my attention. It was supposedly advice on buying a telescope to view Mars this summer. I was happy to see the Mars apparition enter the mainstream, but was disappointed at the buying advice. Why a major news weekly couldn't find a pro or amateur astronomer to write or proof this article is a mystery to me. It was clearly written and assembled by persons who wouldn't know an eyepiece from an objective. To start, the article features images of three telescopes: NexStar 130GT Reflector, Meade NGC60 Refractor, and Orion 4.5" ShortTube reflector. The caption on the refractor will immediately make a knowledgeable amateur wince: "It's computer-controlled, but the mirror is small, so objects may be blurry". There are three factual errors (read on) in just one thirteen-word sentence. And that is very representative of this piece and just the start of a trail of misidentification and bad advice that flows throughout. The theme of "blurry telescopes" pervades the article. I'm guessing that the author ran across the concept of resolving power/useful magnification vs. size and price. That somehow was translated into a fiat that smaller low-priced instruments could only show blurry views. We've already had the example of the 60mm refractor (the one with the "mirror") being blurry; later it is written of small Dobsonians: "but they won't be impressed with a smaller mirror's blurry views". Caution is also called for would-be purchasers of the NexStar 130GT: "it may be a bit blurry" because of the low-ball price. We're told what not to buy throughout the article, so what is the right aperture and price recommendation Newsweek makes for the newbie that is targeted by this piece? Well, the kicker will be found in the final column of the first page: first we read that the NexStar 114GT is "far too small for general use," then the ill-captioned NGC60 is "well-priced" but too small, and then the "impressive" new Orion ShortTube 4.5" reflector is also too small; so the final scope recommendation is a quote from the director of the Perkins Observatory in Ohio: "the best is Obsession's $4,895 18-incher" – really. (To be fair, the article touched on the slightly cheaper and smaller Meade 14" LX200 for $4,295, but didn't make a specific up or down recommendation—just that it is a "latest wonder" in telescopes). Yep newbie -- that’s your scope! The author jumbles a mind-boggling number of misconceptions together in this piece: All computerized scopes seemingly setup and find objects on their own (no mention is made of initial alignment by us humans) – even the ones with just digital setting circles and no motors -- I kid you not: the "NGC60 ($200) finds stars automatically but won't track them" – perhaps you tell it to re-find the star each time it drifts out of view? The refractor vs. reflector debate has been resolved by being ignorant of the existence of the former: only the one misidentified refractor is mentioned. (No mention of the LX200 being a SCT is made). And I got the sinking-feeling that the writer doesn't understand what a Dobsonian is. In the first paragraph we're told that "telescopes are hardly simple tube-and-mirror-devices anymore" and that Dobsoniains are simply scopes that "you have to point yourself". Also, the Orion ShortTube reflector is touted as one of the "new Dobsonians" -- even though it's clearly pictured on a GEM (that's German Equatorial Mount for you newbies)! And there's more advice on what you'll see and how to record your astronomical pursuits. The author admits you're not going to get Hubble views of the heavens through your new scope – the stars will look like "bigger" dots (no mention that this is a bad thing). But you don't need the expense of a scope to start out in astronomy, hand-held binoculars will do (ehh? some good newbie advice?) – but make sure to buy the ones with a built-in digital camera to record your explorations! -- Pietro * - - - - - - - - - - http://www.Pietro.org - - - - - - - - - - * *Astronomy News, BBS, Celestron, Computing, Mathcad & More* *Nail PLUTO: http://www.pietro.org/Astro_C5/Artic...utoCurrent.htm *Celestron 5" SCT: http://www.pietro.org/Astro_C5/c5_nexstar.htm *Astro Book Reviews: http://www.pietro.org/Shopping/ScienceShopping.htm |

I'd love to own an 18" Obsession and I don't fault Burns on any of his
quotes, I agree with them all. And he probably would have been a good choice for Newsweek to have asked to write the article solo. It's just that the author mixed his good advice with misinterpretation and gaping holes (no scopes between $500 and $5k) in such a way as to leave the uninitiated reader worse-off when they enter a telescope store. Most of the scopes "reviewed" are sub-$500 and then Burn's Obsession quote is used to recommend a $5k instrument that is 7- or 8-foot tall and 80+lbs -- this is not the scope for the uninitiated. It read to me like the author was just writing to fill up the column-inch quota for the article.

The reporter asked him if money was no object, what would he recommend. His original recommendation for the beginner amateur was a Dob in the 6-8" range, without computer assist. He told her this instrument is relatively cheap, offers fairly good views, and is a great telescope to learn one's way around the sky. According to Tom, the reporter kept pressing him to recommend a fancy Meade or Celestron, and no matter what he said, in the end she quoted what she wanted heard. Kapella |
