Are you speaking of the Perkin Elmer that screwed up the Hubble ST some years back? I'd be scared

Robert,

didn't you mention Perkin-Elmer as being the coater for your older BB Questar?
At least, that's what Jim R. said when he saw your scope.

I am the original poster of this thread and it was my intention to offer an observation about the current state of Questar and make no further comment, however, before this thread goes completely off topic let me add the following: I feel safe in saying that we all want the same from Questar, the best production telescope in the world, period. The truth is that Questar has met that criterion in an increasingly narrow sense since its introduction. We are now left with arguing that the telescope has superior optics and excellent machining of the mount components. In almost every other respect the Q is now inferior to other serious telescopes. If anyone doubts the longing for Questar to resurrect the brand just look at the post with the most hits in this forum and you will see that Q owners are trying to do for themselves that which Questar will not.

It was indeed. I know you're joking, but for those who don't know, Perkin Elmer was the premier maker of advanced optics in the U.S. The Wikipedia article doesn't state, but I believe they divested that business to concentrate on life sciences. It seems true that Perkin-Elmer bungled the Hubble job, but other than that, their optical reputation was of very high esteem.

Clive, does all this mean that the older bb coating were done better and last longer? due too coater or process? as time has passed and they are still good. john

In theory at least, the older coatings did not last as long, because they were based on thorium fluoride. In fact, Questar reports fewer coating failures with the newer coatings.

Hi John.

I don't have info to make an informed comment on that, one way or the other.
Hard to say if anybody, other than a Q insider with actual data, could answer the question.

In an earlier posting, Robert recounted something said by Jim R. at Questar.
"As far as Jim Reichart's opinion about age, and the effect on coatings, when I spoke with him, he was unconcerned. Most of the scopes he sees from that era are just fine. A decade is the absolute minimum of durability, when stored in less than optimal conditions."
That was in reference to BB coatings from the mid '70s to early '80s.

Thanks All! If my coatings ever fail i would still keep it as a "work of art" sitting on bookshelve or spare parts for another one. john

Go-To? I watched a fellow with one of those scopes... he could not get the scope to slew to Jupiter... what a pitiful sight. I could make this a long story...
but hey what's the point?

I use the Questar setting circles to locate hard-to-find DSOs... (I live under real dark
sky... the finder is more than adequate...) with my "old fashioned" chart
I can dial onto the ONE or TWO objects I wish to OBSERVE in a SESSION,,
Easy-peasy-lemon-squeezy LOL!!!!

So...a fellow starts a post in aficionado forum with "why is it so difficult for Questar owners to see the obvious?" I applaud the responding Questar owners for their patience, civility and continuing good manners in spite of the not so subtle evaluation of their combined intellect.

It's so much easier to be patient and civil when you're the one owning the Questar.

I'm a little late coming in here, and I haven't read all the posts; but let me throw in my two cents:
I dream of someday having a Q7. No way I could even think about it right now, but everything changes. I don't think I could justify a Q90, it's just too small to suit my needs. But a Q7 - now, there's a dream scope for a planetary observer like me. I've never looked through one, but that's only one of many things I haven't tried, but I know I'd like. (TOS prohibits naming some of the others).

Hi Rick,

Every argument made here against the Q3.5 can certainly be made against the Q7. I even had one prominent local dealer in MD try to talk me out of the purchase. But it was one I could afford and never regretted. I am more than happy that I parted company with my IM603 Mak-Cass.

For $4000 I can get an 120MM EON




Out of curiosity I looked this up. It was made by Orion and on their website it says "Not Available; This product is no longer available for purchase."

Perhaps a case of Survival of the Fittest.

Computers come and go. Setting circles go on forever. I don't see the advantage of putting "M27" into a control panel, over dialing M27's coords into setting circles. The circles will keep working for the next 100 years. I'll get the coords from a revolving door of various replaceable computer systems and smartphones over the years. So I essentially have a computer-controlled system with a modular, replaceable computer. It's future-proof and indestructible. And after working with computers all day in my job, the elegant simplicity of setting circles is like a breath of fresh air.

Great line.

Setting circles have an organic connection to the heavens and when I use them I am part of that.

And the aesthetic pleasure derived from rotating the Questar dials is an experience not afforded by button pushing.
