Coulter sold at least one complete 29" Odyssey.

The design was ludicrous.  A solid tube and large wood mirror box.  Even sonotube of that size weighs a ton.

It's not fitting thru my door nor is my back able to handle that monster. That had to have a view filled with coma back in the days pre Paracorr days.  Hate to see what the planets looked like.

Jump on it before it goes to the dump. I know there is a lot of red tape to deal with and such.  USF had a 1950's M-160 Unitron that sat around for years and i sure tried to buy it back around 1981.  Dr Carr told me they would rather throw it out than sell or give it away back in the day.
 

I tried, couldn't even get a meeting. Had a whole team ready to make it happen.  :>(

 

And no, it isn't used now, not ever...

I don't get it?  Lazy people i guess that don't wanna deal with it.  The schools can make a little money it seems.

Another dream scope to me back in 1977.

That makes 2 of us -- though I bet there are many more here on CN...

No telling how many Astro Optical & Yamamoto Refractors SEARS sold in the 1960s & 1970s...  The Model 6345 90mm Astro is the largest that I know of:

 

attachicon.gifSears Model 6345 (CN gregju) on A-Mart 201606 P01.jpg

 

I think the Royal-Hex rotary eyepiece holder, with it's color-coded slots + matching eyepieces is crazy cool (and I know crazy).

 

 

There’s a 6” and 8” listed in a later Astro Optical catalog, but it definitely was never sold by Sears.

Chris Charen in NZ started a thread about his Yamamoto/SYW 108mm unit here: https://www.cloudyni...m-review/page-2 but I think someone else (possibly here in Oz in Melbourne) had a number of these & posted here in CN with even larger objectives...112mm or 115mm? confused1.gif

The 1972 Royal Astro Optical catalog shows a model R-151 150mm , 2215mm FL (f/15) refractor on a massive pedestal mounted equatorial head. It is apparently motorised on both axes. The compendium of eyepieces include three orthoscopics and three Kellners. The accessories include a Herschel wedge. An impressive telescope.

Still had to cost someone something when new. I figure today it would be 300k or more.

Considering the catalog is from 2005 and the price was $20K then I doubt that it would be $300K today.  Maybe more like $25-30K

Cave had a 16" F/8 Newt. Talk about a brute trying to lift that OTA on the mount.  No may one person could do it.

Cave made a 18". Probably only one.

Ugh. I try and forget about the Cave 18. I saw one listed in classifieds years ago, painted red, but the ad was gone nearly as soon as it appeared. Seller had no idea what they had, and just wanted the massive thing gone (it was all crated up, as I recall).
