Optics are better now than ever. So why are
magazine reviews the same as they were 20 years ago? Now that the market is awash in apos, and now that SCT optics are so much better than 15 years or even 10 years ago, and now that you can buy large Newtonian optics/scopes from a few excellent sources, it's time for the magazines to dispense with the "man in the street" reviews and concentrate on doing real testing of these optics. Tests on these scopes should not be limited to the casual viewing tests current being done by the people at the magazines. The optics should be tested on proper optical test equipment. The only value to their kind of field tests is to see how other variables like temperature (and cooldown time), and actual use effect the scope. Maybe they find an in-use problem with the mounting, whatever. But two such reviews of similar telescopes tell you nothing about how they perform "relative to each other" and that is the information the consumer could use to make a choice. The reason for this is simple. The magazines need to stay at least one step ahead of copious online reviews by experienced observers in order to remain relevant. Right now, the magazines are behind. The only thing that keeps them marginally relevant is the variability of the quality and accuracy of online reviews. Why are online reviews better? Because oftentimes the internet field reviewers have at their disposal more than just the scope in question and are able to do direct comparisons between two like scopes. This is something RARE in the magazines. Rarer still are actual optical tests, as opposed to ronchigrams and vague references to the star tests being "very good." If one more reviewer testing a mass market scope reports "identical inside and outside of focus" star tests.... The only way the magazines can differentiate themselves positively would be to establish optical standards that could be used as references whenever they test a telescope. Concrete standards. Measurements. As opposed to the awful, good, better, best nonsense that passes for some review standards now. Say someone is trying to decide between two apos, a TV NP101 and a TMB 100 f6.5. Even if the magazines reviewed the two scopes in the same year, the way they review and their inability to differentiate between two optically excellent high end scopes makes a consumer choice between the two a toss up. They could say the TV has a faster focal ratio so will provide a wider FOV, but what if the person wanted to know which scope has the edge on planets? Basically, they only know that both scopes will work well, but for $3500 they might like to know which offers the edge. I think the oddest thing is that magazines are easily willing to provide information that the manufacturers already provide, and reinforce that, but they are somewhat unwilling to provide information the manufacturers don't generally provide, like ultimate optical performance. Why should the magazines do this? One, to make them relevant, two, to allow them to be more relevant than the online consumer reviews, which tend to vary in their accuracy, depending on the reviewer. Can the magazines do this? Yes, they have the resources, they have the time. If the goal of magazines is to provide enough solid information to consumers to make themselves interesting and valuable, they have to be better than what is now free online. If you take all aspects of a magazine and compare them to the free online information, you will see they are losing ground. -Rich |
