Great article! I actually remember reading it when it was first published! I was sold on AP triplets after that.

Rolando also has a article in the October 1985 S&T as well.

It's from a time when people actually looked thru a scope with things called eyepieces (and had telephones attached to walls, with rotary dials on them).

It’s amazing how useful a Christen triplet from that era remains as compared other contemporary technological innovations such as the rotary dial telephone. Some things really do stand the test of time.

Anyone seen a video of a millennial attempting to use a rotary phone for the first time without instruction? Hilarious. What we take for granted is already lost to the ages. -Best, Robert

I can (barely) remember when rotary phones would have been called "high-tech", except that the term had not been invented yet. Would you folks know what to do if you put a phone to your ear and heard someone saying "Number, please"? (Wouldn't that be a cute feature when opening a 'phone app?) And there are still plenty of telescope mirrors that predate Roland's triplets, and even predate Roland, that are still doing yeoman duty today. -- Jay Reynolds Freeman ---------------------Jay_Reynolds_Freeman@... http://JayReynoldsFreeman.com (personal web site)

Guys – Did you say Party phones that went along with the patch panel? And scary glow of the lines when a lightning storm went through?

Hey, I still do!
On the rotary telephone angle, I was a fleet inspector for Ma Bell in the 70’s back in my mechanic days with about 400 vans, pickups, ladder trucks etc to manage. I clearly remember the day of the breakup of the bell system because there was a long line of installers grabbing all the bell telephone gear, handsets, recording machines, as they realized they could go into business for themselves as installer/repair men! I got what was left, pushbutton handsets, one big answering machine and other stuff! Still have my rotary dial and digital push button test sets! I made it my business to pickup on the telephone side while maintaining their vehicles! Rossmon

I was impressed with the Astro-Physics advertisements featuring Christen ladies in front of A-P's latest and greatest and wondered if there was some precedent. I found an article that mentioned a Southern California telescope vendor credited with the first "modern" approach to sales marketing. It included a photo of the vendor's line of Newtonians with a female model showcasing the scopes in front of the store. Wonder if Roland had any relationship with the vendor or otherwise emulated the advertising which is attributed akin to advertising used by '50 - 60's car dealerships? -Best, Robert

Yes. I can recall the day when no one had anything but a party line. A private line was considered quite a luxury. Not only were your conversations open to the public but you had to wait for a busy party line to clear before you could make your calls. Back in the day I think our number was only 5 digits? -Best, Robert

THANK YOU James for this! I remember that article as I've been
reading S&T since 1973. Great seeing it again.

Hey Roland, that's all I do :) No cameras on my scopes. But

And the worse part was when you screwed up with the dial you had to
hang up and start over. Been there, done that.

That would have been Cave Astrola's units, if I recall correctly. I believe that especially petite models were particularly in demand for those ads, to make the telescopes look bigger.
