Thank you for the update Robert. I'll get it in the next edition. And congratulations on another Cave!

 

I had a note on that one that it was also engraved "DK", wondering if that meant Dall-Kirkham? 

Yes it is engraved DK.

I was reading most of the Cave cassegrains are Dall-Kirkham.

Nothing on the secondary noting DK, so maybe all 10 inch by this time were DK.

I recognize the hand writing on the secondary as Cave.

I'm not sure what the underlined 'Perfect' means, perfect sphere? which is what

it would be for a DK.

 

Robert

Thank you Robert. It appears fairly obvious that the DK means Dall-Kirham.

Hello and welcome to the Cloudy Nights Classic Telescope forum. And thank you for the addition to the registry.

 

I know what you mean regarding sending the mirror out. I've done it several times and was always very nervous until it was safely back in my hands.

 

I will have your mirror in the next edition of the registry, which I'll probably post next month.

Good evening y’all, 

 

I’m new to this group so let my dad and I know if we do anything wrong.

 

My name is Patrick and I’m a senior at the University of Colorado Boulder where I study film directing/writing and astrophysics and planetary sciences. My dad was the person who originally piqued my interest in astronomy and we recently decided to clean up and semi-restore his 10” Cave Astrola Deluxe Portable (what we believe it is). We just cleaned up the mirror (which was covered in grime) to reveal a beautifully clean and surprisingly illuminated surface. I took down the information and thought I would post it here.

He traded a small telescope for this telescope (a hell of a deal) because the other guy’s wife said “it’s me or the telescope”. Needless to say, we’ve had it since the 70s/80s. I’m glad to see other’s caring for these old beauties and I look forward to chatting with you all in the future! 

 

Best,

Patrick & Stan Wine

Hi bobdog and welcome to the Cloudy Nights Classic Telescope forum! Thank you for the addition to the registry.

 

Can you tell me if the Cave Optical Co. engraving is in block letters or cursive writing? Even better, if you have a picture of the engraving that would be great. Pictures of the entire telescope are also welcome. Everyone here loves seeing old Caves still in use!

 

I will have your mirror in the next update to the registry that I will probably post tomorrow as I have a number of new mirrors since the last edition.

Hello Patrick and welcome to the Cloudy Nights Classic telescope forum! And thanks for the addition to the registry. If your Cave has rotating rings and a clock drive, as most 10" models do, it would be called a Model C Deluxe. If it also has all the aluminum parts polished and the steel parts like the pier tube chrome plated then it is a Model C Custom Super Deluxe although these are fairly rare.

 

Do you recall if the Cave Optical Co. engraving is block letters or cursive writing? This is another feature of the engraving that I track. Any chance you took a picture of the engraving?

 

You will find a number of Cave enthusiasts in this forum, myself included of course, who can help with any restoration questions you have. We also love pictures of classic Caves so feel free to start a thread on it and post away.

 

I will have your mirror in the next update of the registry which I will post soon.

It's time for a new update. We have 5 new mirrors and a few other updates.

 

Changes from the 1/26/2020 edition are highlighted in yellow.

 

Cell in red is an entry where I hope to someday verify the date as it doesn't make sense. This was in the description of a Craig's List ad that is long gone. If anyone ever bought mirror 1368 I would really appreciate a picture of it.

Hi Jon,

 

Will you please add this 8" f4.5 s/n M651295 from April 26, 1965.

 

It was recently re-coated and should see first light (or better yet second, third... light) next week.

 

Thank you,

Don Clark

Hi Don and welcome to the Cloudy Nights Classic Telescope forum!

 

I actually already have that mirror in the registry. I saw it for sale on Astromart a few years ago and noted it. But I will update the owner to you. Thank you for the update.

The Cave Cassegrain #M748960 has changed hands from vvalmiki to clamchip.

The mirrors are now in my possession I'm still waiting for the tube to be shipped.

Primary is M748960 39-5/8" FL March 23rd 1974

Secondary just says 10 inch cass secondary Perfect

 

Robert

I now have the complete optical tube, many thanks to Vinay for making it all happen.

There is no mounting, it changed hands a few times, and I'm not exactly sure where

the optical tube came from, but unfortunately they are separated.

I feel fortunate to own the optical tube, a Cave Cassegrain is a telescope I've always

wanted.

That is fantastic Robert! Mounts do show up occasionally. Making a taller pier tube for the Cassegrain would obviously be easy.

It is, but it's surprising how hard it was to find the right size tubing.  I ended up with Aluminum tubing, because it was a lot cheaper to ship than steel:

Excellent! Thank you for the addition. That does look to be in great shape. Hopefully the rest will be a straightforward restoration. That scope has an unusual set of options for a Lightweight Deluxe. I don't think I've ever seen one with a dec drive.

Hi Ed and welcome to the Cloudy Nights Classic Telescope forum.

 

Thank you for the addition to the registry and the pictures. I just published an update a couple of weeks ago so it might be a bit before I get another out with yours in it. I usually do it every 6 new mirrors or 3 months, whichever comes first.

 

Your mirror has the distinction of being the highest number I now have before Cave "rolled over" at 10,000 mirrors in the six digit serial number sequence and narrows the date when this happened a bit. It looks like it happened about the third week of November 1974.

Hi everyone

 

i purchased my 8” F7 Cave Astrola Light Weight Deluxe about 3 years ago. It has been a great planet killer to observe with and the images are tack sharp when seeing allows. I finally decided it needed to be recoated so I took it out of the cell and will hand deliver it to Ostahowski Optics which is about 2 hours away tomorrow.

 

i just mounted the OTA on an IOptron IEQ45. What a joy to use on a more stable mount.

 

The side of the mirror is hand inscribed 

 

M749724 CAVE OPTICAL CO

55 5/8 FL OCT. 16 1974

Yikes! A high viewer. I am sure the mount is 10 times better than the Cave mount was. Maybe a lower tripod or pier. Seems the OTA would hit the legs in parts of the sky.
