Now that I have scopes again, I've been wandering them about the sky. Not target acquisition (well, aside from some revisits to old friends, M42, M45, and Saturn the other morning, and epsilon Lyra the first night) I'm really not very good at target acquisition. But just wandering about I've seen some lovely groups of stars, and some elegant color contrasts (very nice yellow-blue pair in Lyra-Cygnus, somewhere, ... oh to find my way back :-) ). On the off chance you're serious (and for those out there who don't know what he's talking about), this is Albireo (beta Cyg), the beak of the swan (or the foot of the cross), one of the finest binocular and telescopic doubles in the sky. To be serious: no, I'm not positive that it was Albireo. I wasn't paying attention to where I was drifting the scope. My initial move was towards delta Cygni, but I could easily have changed my mind. Given the description, though, in Burnham, it almost certainly was indeed Albireo. It's been cloudy here since then, so I haven't had a chance to verify. Lots of interesting things up there.

In the Dec. issue, the editor of Sky and Tel in December discusses Christmas present telescopes. He of course makes mention of the junk scopes, the 60mm 525x refractors and 76mm reflectors that are mechanically and optically (usually by their eyepieces) challenged and that they do more to turn people off the hobby than turn them on. This is undoubtedly true. But forget the 76mm reflectors, the main culprit is the 60mm refractor on it's 9000 year old Tasco alt-az rickety mount that is by far the main culprit, along with it's dog crap little Huygen eyepieces and 3x plastic barlows. So, has the mere presence of these telescopes harmed the hobby, by driving many away from it. I used to have the view that if someone couldn't maintain their interest enough to "live" with a 60mm for a few years until they sought out something better, maybe they didn't deserve to be in the hobby, that their interest was not genuine. But, after having watched the behaviour of amateurs over the past 35 years, I realize that some (more now than before) come into the hobby and can be turned off by bad equipment. Whether they "deserve" to be in the hobby is purely a judgment call on people's part. So if most agree that the lowly cheapo 60mm refractor (or worse, the fully plastic 40 or 50mm trashfractor) has turned away potential devotees, what can be done about it? About 17 years ago, Meade and Celestron tried to help out here. They both offered only decent (not great, but workable) 60mm refractors with reasonable 1-1/4" eyepieces and real finderscopes. This was a noble attempt by them to "upscale" the beginner. It worked for a bit, but ultimately, both companies for whatever reason decided to dispense with all pretense at being the hobby saviours and started selling the same garbage scopes Tasco and Bushnell and Swift, etc, had been selling. They needed the high margins these scopes offer. They probably help offset R&D and production costs of real scopes. The editor of Sky and Tel offers up the usual advise (which is good) about trying educate people about bad versus good telescopes, but amateurs are too few in number to influence the bulk of telescope buyers who are looking generally for just another Christmas gift to offer up and who don't put anymore thought into it than someone buying a shirt for someone. In fact, someone is more likely to know a good clothing brand than telescope. But what if the only scopes offered at the entry level are decent quality ones? Celestron and Meade tried this a decade+ ago, offering decent beginner scopes, 1-1/4" eyepieces, good finders, etc, but they couldn't sustain it and started selling the junk themselves to compete with the odious Bushnell and Tasco. So, over the past 40 years, had good scopes only been offered, would there be more amateurs in the hobby today, or (despite the rejection rate of the junk) are there more in the hobby today because of the sheer number of cheapo junk scopes that have been turned out? If you sell 100,000 good scopes, and 80% of the people stay in the hobby, or 500,000 pieces of junk and 200,000 stay in the hobby, obviously the junk scopes did a better job. So have the cheap refractors hurt or helped the hobby? -Rich Hi Rich!No I dont think that the 60mm refractors have hurt the hobby at all.I think that their manufacturers claims tend to discourage some beginners after they have had them for a while.I am familiar with TASCO because I owned a 50mm(2") refractor 100x ,and a JASON 280x Constellation 60mm refractor.Both gave me fine views,but I educated myself on telescope terminology and avoided the high powerlow aperture trap,so that I was able to enjoy use of the scope.Those scopes were built better without much plastic.The TASCO 2" even had an all metal rack and pinion focuser-it was the 6TE-5.My friend Melvin logged a sketch of the waning gibbous moon using it back in 1972 October (The drawings are in my 1972 Journal).I think that the optics of todays 60mm's are better than those were.My suggestion to the 60mm user-take the time to learn your telescope and its capabilities.Learn how to use it and get some good books on scopes or join an astronomy club.Perhaps a 60mm telescope users group would be helpful.After you learn your scope,you can upgrade to a larger one or upgrade your 60mm scope with better eyepieces.Though these new scopes are built like junk,a little work can make them into decent units.Ya just need a little fire in the belly!Gary Barabino Sr |
