Long before Mike and Stephen posted actual first hand opinions regarding the OA-6.5 and my 90mm ATS-OA there were a bounty of opinions based without any first hand knowledge/experience. And I believe to say anything other than that is pure revisionism. Dan, One thing I love about s.a.a. is the way folks completely ignore questions. I asked you a very simple question, and instead of an answer I get a snotty "Please....." I have neither said anything about the performance of one of your OA scopes, nor invoked anything from some other thread. My point was also about someone making claims about two telescopes - sight unseen. I think I have better things to do now. Alan, Fair enough. Regarding Mike`s comments regarding the OA-4 vs. Orion`s soon-to-be available 100mm f/9 ED? Well, on a 1-10 ludicrousness scale, about a 3, considering Mike`s experience with my OA-90mm vs. similar aperture and f-# scopes. Dan --- Outgoing mail is certified Virus Free.

How about we just bemoan losing the Lone Ranger and Tonto, instead?? At least
they had great background music instead of a lot of bitching-out back and forth..... g Clear, Dark, Steady Skies! (And considerate neighbors!!!) |

Where's
your proof that TEC is so great? Can you fill us in? Make sure you send out all your notes, perform double blind tests etc etc.... Mike. Hello Mike , Rat and group , I can say unequivocally that the DGM off-axis OA-7 reflector ( speaking for mine only ) and the TEC APO-140 ( speaking for mine only ) are both just excellect telescopes . Both different , both excellent . That has been my experence with each . I have not had a problem with either scope but feel each Co. would back up its product completely . This thread needs to be put to bed . Best of luck to each of you with your scopes , I know Rat has a thrill coming soon ! May the clouds depart and give a each of us a good night soon ! Leonard |

To reach me directly, remove the Z, if one appears in my e-mail address... "Jon Isaacs" wrote in message ... That's the name of the product line (like Telestar), but Meade doesn't hide the fact that they're selling these telescopes. In fact, many retailers bank on the company's name. I agree, "Its a Meade..." Not that it makes a difference to me personally--if they want to be like Tasco, it's up to them. As a result, however, I would not recommend Meade (or Celestron) by name. I agree. I feel comfortable recommending Orion stuff because Orion seems to try to put together the best package for the money rather than trying to put together the "best selling" package for the money. A couple of 1.25 inch Kellners with a 60mm F11 refractor can provide some nice views... jon I'm a little worried about all this agreement here on SAA, but I agree with you... I just got Orion's catalog #046 with the 100mm ED on the cover. And while I wouldn't exactly call these high end refractors, they certainly MAY offer the best value for the money out there (though just how good the 100 is remains to be seen)... I have been an Orion customer for decades. Almost from the beginning. And I don't feel bad about having said that at ALL... Cheers! Jan |

Prestige for the purpose of selling PowerSeeker and Polaris (Tasco wannabe) crap? Sure. Especially if the typical beginner won't recognize it as crap. They'll think, hey, this is Celesteade (or is it Metron?), I'm sure it's good, it must be my fault. I must not be any good at astronomy. Or, at least, that's my concern. You're essentially implying that in order to maintain a shaky market that is beneficial for us, these companies must prey on other people's ignorance. Nah. I'm saying something a bit more damning--that the companies will prey on other people's ignorance whether or not we buy the good stuff, and if we don't buy the good stuff, they have no great compulsion to continue to sell it, and then we'll have *nothing* but the crap. At the moment, however, I'm focusing on what to tell beginners, and I'm obviously not going to say "You can't go wrong with Celestron or Meade." :-) Nor I.

![]() "clyde crewey" wrote in message om... Stephen, So, at this point the only think left to do is get back on topic. It's easy to agree that the Ranger and the Pronto are no more because of the 100mm F6 Chinese achros and the ED80 kill them in price competitiveness. However, while the ED100 might be the deathnell of the TV102 on price, the DGM Optics OA4 is still a better value, and anyone seriously looking at an ED100 on a CG5/SVP, might want to consider the comparative luxury of the ultralight OA4 on a Dob mount. That's all I had to say on the subject in the first place. Well, as I said, I don't agree with this at all because it's not true. Or only partially true at the most. The Pronto/Ranger were slated for extinction when TV introduced the TV76, and yes, I know that for a fact. I didn't know that. Hence, it was easy to agree it was the result of the "China syndrome". g The TV76 was introduced well before the ED80. As I pointed out, the TV76 is the exact same size and weight as the Pronto. In fact, it uses the exact same tube and focuser. The writing was on the wall for the achro's when the 76 had success. The TV76 is the concept of the Pronto perfected, and ditto for the TV60 and the Ranger. Al made a decision to phase out the achro's and that's really the story. I've often been tempted by the TV-76, but wanting aperture in my short tubes, I lean toward the 85, and the 101. As for the ED100 being the death knell of the TV102, how do you figure that? Well, I don't really. Someone else does. I simply said "while it _might_" be true (on price), it doesn't mean much for the OA4, which, while much cheaper than the TV102, remains cheaper than the ED100 still. At best, that makes it reasonable competition, leaving the buyer to consider factors other than focal ratio and aperture, which they share virtually in common. The way I see it, the TV102 surviving all the years of OA availibility is sort of a mystery, considering the comparative performance, and radical price difference. But, people swear by their apos, even though a much larger reflector can be had for far less money, and even though the vast majority of them are fully aware that the larger reflector outperforms their apo on just about everything. So preference for those unobstructed views, whether openly admitted or not, seems to be playing a part in their enjoyment of observing, just as I have seen from the OA over a larger reflector. As for why the less expensive OA hasn't taken a big chunk out of the 4" F8/F9 refractor market, I can only assume it has to do with mass inexperience with the design. As many folks as there are who seem to have a lot of experience, it's hard to imagine that someone like myself, who has only been at this for 3+ years, has sat down and compared the OA scopes in A/B testing with larger reflectors and apos, and they have not. While I don't have the experience and expertise to be able to describe the details of the objects compared, and thereby give a "pleasing" review to the officianados among us, it is my experience that there is insignificant difference between the OA and the apo, for the range of powers (actually fields of view) where they overlap. But anyway, people need to see for themselves, just as I need to see through the ED100 before forming an opinion about it in particular. My apo experience is limited to a session with a TV-76, another with a TV-85 and several with a TV-101, and of course the 2 minutes with the now infamous TEC140, which was being negatively affected by some anomaly in the optical train. Meade has had a 102 ED out for years at only $100 above the price of the ED100 and that hasn't killed the TV102. Why would the ED100? And why wouldn't the ED100 be the death knell of the Tak 102 if it's going to kill the TV102? As someone who has used both of those scopes visually, you can throw a net over them performance-wise. BTW, my 6" f/8 Dob beat them both on Saturn! (And yes, the Tak owner admitted it!) If one considers ease of detail seen as "beating" The C ring was visible farther around the planet and available at a lower power in the Dob. However, both 4" APO's provided what could be certainly be called a more pleasing view. On low contrast Jupiter, it was really too close to call. On the moon, we both picked the refractors. And so it goes with the OAs. Refractor like views from a reflector. It really is that simple. Regardless of any egregious claims I might have made in the past about its ability to best an obstructed scope of larger aperture. Whoops, sorry, I'm off topic! No, I am. Regards, Stephen |

I think the preference for apos is an aesthetic isssue. Even though I collect less "data" through my refractor than I do through my larger newt, I am charmed by the beauty of the subject matter and thats a great thing after a hard day's work. I don't mean to imply that the views through the newt are ugly, far from it. Maybe its that I have no illusions of contributing to "science" and I spend time under the night sky in part to restore myself. A 3-4" apo can do that for me. The natural views and the intuitive motion (alt/az) tend to make the scope disappear as I am carried away by the awesome context we live in.
