It appeared to be a very innovative rubber band...
Or, if you can't listen to a brass band at work you might as well look at a rubber band...

Maybe "someone" or "something" is keeping track of what we do.

I'm not sayin' it's so, I'm just sayin' maybe.

It turns out this will not be our last star party of the year. Due to a nice weather pattern here in Utah we have decided to hold one more under the lights on a grocery store parking lot.

The big refractors won't be there but we will be well represented anyway. I'll bring the 160, Steve will bring either the 6 or the 8.

Y'all are welcome.

Thank you for the compliments.

This thread has now had over 4,000 downloads. 18 pictures have been downloaded over 100 times, 1 over 200 times.

It is still amazing to me though that a rubber band would have 28 downloads and a cut rubber band would have 13. I'm not sure what that says about this group.

Don't know where to start about your 9"F/14 AC refractor, so all I can say is BEAUTIFUL !!!
(While visiting in South Africa my daughter took this photo many years ago of
a Zeiss refracting telescope. I'll include her photo of the objective lens in a later post here.)

Zigster..how in the world do you know that information and how did you attain it?

Here is the photo of the Zeiss objective I spoke of in my earlier post. If I remember I think it may have been a 10" F/12.

The engraving on the lens says 30cm. Is that a 12" lens? If so that's a WOW factor.

Maybe that is 301cm for the focal length?

I think you may be right. That would make it a 10" F/12.

It looks reasonable. Strange way to designate it though unless the "B" stands for Back Focus, then there's the dot and equal sign followed by "30", and is that a "1"(?) "cm". The "1" looks incomplete.
