Lunt Imaging

Posted By Alex McConahay
It looks like nobody else has had this problem. At any rate, I solved mine by using a recessed 2" to 1.25" adapter. I removed the setscrew, and replaced with a recessed allen head thumbscrew. this gave me an extra quarter inch in-travel.

Now that I can focus, all I need to do is learn how to take a picture with the thing.

OK, now what can we make with it?

Posted By Alex McConahay
If this stuff realizes its potential, we will see nothing.

It is half of the device used to make things invisible.

Dealing with eyepieces...

Posted By Alex McConahay
You know, for any given telescope, you only need about three eyepieces. THese can usually fit pretty easily in the same case you fit your tube into. Just have a little piece of foam cut out in such a way to accommodate the eyepieces that fits in some wasted space of the telescope (or mount) carrying case.
(unless, of course, you don't carry the tube in a case, either.)

Pronouncing funky star names

Posted By Alex McConahay
I owuld not worry about it all that much....just hang around other astronomers and listen to how they say it. There is no common agreement on how things are pronounced. There are several authoritative guides to it, including one published a decade or so ago in Sky and Tel, I think---but fact is, these are dead languages, and nobody knows just exactly how they were pronounced. (Even Latin, one we pretty much think we know, gets pronounced differently depending on where you learned it.)

Physicist Murray Gell-Mann is famous for correcting people on how they say their own name. I don't know whether that is true or just a legend. But, let's face it, things are what they have become.

Ethos clone on the horizon

Posted By Alex McConahay
Oh yes, it had made its appearances.

It made a buzz out at Goat Mountain Astronomical Research Station--Riverside Astronomical Society's deep sky site--last weekend.

Is this excessive?

Posted By Alex McConahay
Greg,

I think it is excessive, and perhaps in violation of the terms of service for Astromart. The TOS forbids posting individually identifying information such as phone numbers, email addresses, or post office addresses. Posting the shipping confirmation means posting the ship from and ship-to information, I would assume. And that would, therefore lead to posting the identifying information.

Besides--You already have all this information in a record. Just do a screen print or print the email of the tracking record. If somebody is going to dispute that, they are just as likely to dispute whatever photos or other information you are posting back to the "Sold" column. I think your original ad should remain as is (with the exception of the "sold" notation). That makes a better record than an edited one.

Ebony Star??

Posted By Alex McConahay
The big key to Ebony star was the pebbly (as opposed to smooth, perfectly flat) surface. If you can find a "formica" (another brand name that has become generalized to any one of a number of hard surfaced veneers) that does the same, it should work.

Sold as Celestron CG5, but what I got was not Cele

Posted By Alex McConahay
I can tell you that when I bought my CG-5 under a C9.25 in the year 2000, I did not get what I would get today as a CG-5. It was much flimsier than what they are now selling as the CG-5. And my mount nowhere said Celestron on it-----So, there may be some room for error here. I no longer own it, so I cannot measure the legs, etc. And I have not seen the pictures to compare--but I can tell you that if I were buying a CG-5 today, i would be sure to check what edition I was buying before sending money.
