Now getting back into the astro hobby after a few years recess, I've noticed
a trend towards refractors. I visited a local SP a few weeks ago and I'll bet close to 70% of the scopes there were refractors. I'm curious as to what's caused this trend or shift as when I was active in the past, close to 15 years ago, the "light bucket" Dobsonian seemed to be the favorite at star parties. How does a refractor, which I seldom see in apertures greater than 100mm due to expense, compare with a light bucket Dob or reflector? It certainly can't be DSO's as an 18" Dob would win that battle hands down. I would also think that the larger reflector would be the winner for planets too, especially if it has a good mirror. So, what is the appeal? Portability, but what else? There must be something I'm missing regarding their appeal especially when you compare the cost per aperture differences between refractors and other scopes. Thanks, Juan |

I don't know if there is a real craze, a marketing craze, or no craze at all. But I do know that if you go to a star party, not one telescope in 20 is a refractor. People who actually use telescopes visually know what makes sense. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

A lot of people use them for imaging, which you are not going to see at star parties. It is hard to do with normal Dobs. People who buy high end apos know exactly why they do so. Roland Christen |

Refractors are a better instrument for their size than newts or dobs. they're better for photography, deployment, contrast, and ease of use. Big dobs/newts are a drag to move around, the tracking is cumbersome, and they require ladders/stools/etc to have on hand to cover the zenith, or anywhere near it. Refractor images are excellent, they are portable, they are outstanding visually AND photographically. In a nutshell, the refractor is the perfect ALL around scope. That ability to go deeper either visually or photographically is not up for debate, everybody on SAA agrees (or should) that big newts and dobs go deeper(in less time photograpically, and all the time visually) But that doesn't make them (for most users) appropriate, considering all of their downsides. The refractor is the perfect telescope, and people who buy expensive ones usually have come to that observation on their own, with no counseling from this group, or any other. Nobody is going to spend three grand on a refractor (or not) based on anything anybody in SAA has said, they're already way beyond that and making up their own minds based on experience. What happens at star parties indicates trends of a very, very small percentage of star party attendees. And you're wrong to boot.....the largest refractors, the newest refractors, and the coolest refractors are always at big star parties, so I don't know what you're talking about. The fact that there is ten times as many scopes at a star party that cost five times less than a big refractor isn't indicative of anything beyond the fact that there's always less of the most expensive/desirable item at any hobby gathering. |

That is a matter of opinion (yours apparently). I don't happen to agree. I don't really think there is such a thing as a "perfect ALL around scope". And you're wrong to boot.....the largest refractors, the newest refractors, and the coolest refractors are always at big star parties... All I said is that there are many more reflectors than refractors at all the starparties I've been at. I figure that's because when people take a lot of trouble and head for dark skies, they really want aperture- and that's something you don't get with refractors. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |

Refractors are a better instrument for their size than newts or dobs. they're better for photography, deployment, contrast, and ease of use. "for their size" ie, to simply say refractors are better instruments is like saying a top fuel dragster is the best car because it goes the fastest. (and some here would agree! vbg) At the same time, I don't want to bring the groceries home (or haul a telescope to a dark site) in a dragster. A pickup will haul a lot more than a dragster, even if it isn't as fast. In the same way, scopes have different advantages. Big dobs/newts are a drag to move around, the tracking is cumbersome, and they require ladders/stools/etc to have on hand to cover the zenith, or anywhere near it. Yes, but if you want to haul out to a dark site and hunt for the faintest DSOs, nothing beats a big dob. Refractor images are excellent, they are portable, they are outstanding visually AND photographically. True, providing you aren't chasing something that takes 14" of aperture to see. In a nutshell, the refractor is the perfect ALL around scope. Ah, now I get it. You're just a TROLL! Clear Skies Chuck Taylor Do you observe the moon?

What baloney. Bottom line: you can see a lot less with a refractor than with a "big dob". Maybe it's good for the lazy. I notice that those folks also are not willing to travel to dark skies much. In terms of $$ per the number and quality of image there's no contest between refractors and "big dobs", the dobs win every time by a huge margin. Little telescope are fine for people whi o like to spend their observing time splitting double stars. I think most of us want to go way beyond that. The exception? Imaging.

When is your "book" coming out? I would buy it, sight unseen!
