It was not a 6" really. I wanted to take no chance on someone here taking this scope away from me. 

 

Oh man! What am I gonna do with all these stupid 6" Caves that I've been buying up?

 

Seriously, though - that's a beautiful looking instrument. May it serve you well.

It was not a 6" really. I wanted to take no chance on someone here taking this scope away from me.  Mirror is soaked from being in a cold truck for hours and into my 90 degree temps.  Got a fan blowing it dry now and should test it out soon.  Mirror is Cervit so we will long it takes to adjust.  I will have more info when i get time.  It is a 10" F/6 and came with another 10" Tube, spider and cell mel.

Nice  scope  and good job    Bob

 

       and that was  very  sly     Guy       just saying

 

              and just  cuz you are paranoid doesn't mean that aren't trying to steal your deals Neil

One look at the Double double told me all i need to know.  I got a Zambuto in a classic tube.  The not so good, mount has lots of slop. The Sky Mirco won't go out far enough to focus many of my eyepieces.  If i remember there could be a slip in draw tube and will check when it is day time.

 

Scope is 95% collimated and the moon and Saturn looked good in the soup.  Ring and M13 were nice with great contrast.  Double double was just clean and sharp like in my Mak.

 

Scope will stay as it is, but the green is going and the mount will get a good working over. Finder is like new for being 42 years old. Odd it don't have a cross hair eyepiece and it is .965OD".    Not sure what i will do with the extra OTA.  Tube has some damage on the end, but would be fine for a F/5.5 or faster optic.

 

More pics of mirror specs and scope to come later.

I knew it was the one in GA. No worries in anyone taking it away casue the ad has had over 500 hits and been for sale for 20 days. These large Newtonians aren’t very good sellers anymore, unless you give them away. I’m sure it has a good mirror but it been refigured by Galaxy Optics back in 1988. It may very well be the best 10” you’ve owned, too bad it’s not an f/7 or f/8.

Let mo know when you’re ready to sell, I may want to trade my Takahashi straight up for it.

It’s a beauty. Congratulations Chas. I hope you keep this one for a while. With your seeing you absolutely have to keep it through the next planetary season.

I saw that ad some time ago, but having the portaball I decided to pass on it.  Besides I was not going to drive to Georgia.   Glad Chas picked up a nice scope.   wonder how long it will be before we see it up for sale.  When it does I want to see it for sale at $895 or less.

Chuck would love this stuff.  It came with a grab bag of toys.  Meade 60mm guide scope and illm eyepiece with control box. Never used Hurst motor and a complete extra OTA minus optics.

Never used Hurst motor. There is also Dec axis motor and gear set that looks home made.  This scope was bought around 1975-76.  Seems it would have to be a custom order since it is a Cervit blank.  My guess the tube was changed for whatever reason.  The newer tube has a Novak spider and mirror cell. The scope came with a extra set of rods with weights for the rotating rings.

 

The mount needs some work as it sure will flex.  Latitude was never changed from the first owner in VA.  In 1988 the Cervit blank had a refigure from Galaxy and was recoated in 2004 and was stored until this year.

Thanks. It took a 3mm Delite on the moon without a problem. The mount was not up to the task. Not sure why i am getting so much flex.

it could be the latitude.  I read somewhere that some mounts will just not work correctly at certain latitudes.

I think it's a good thing your scope is f/6 Chas.  And congratulations, she is a beauty.

Having recently restored a Cave 10" f/6.8, I think we are about at the limit of the 1.5" Astrola mount.  I took mine apart and cleaned it.  Until I balanced the optical tube the mount was jittery.  You have 2 finders and the focusser and eyepiece all on one side of your tube.  And all that unbalanced weight lives about 8 to 9" off axis if you don't hsve the tube weights That is a large unbalanced moment arm.  Once I balanced my OTA the mount worked better.  The f/6 tube is a shorter teeter-totter in declination than a longer focal length optic so that is a good thing. At the same time you have a lot of weight at each end of this Dec teeter-totter.  The guide scope looks cool but further loads the mount on both axes.  With so much unbalanced weight you have to over-tighten the RA clutch and tighten down the Dec screw just to keep the scope from moving under its own weight.  My mount, balanced, moves like butter and stays where I put it.  Yours can too.

I guess 1976. Won't know until i take it out.  Already got the mount tore down. The allen screws did a number where you adjust latitude. That was always a weak link with these mounts.  It is going on my G11.

 

I gotta rig a G11 pier adapter to fit on the Cave pier.

The latitude screws were all loose and chewed thru the metal.  This mount will be stripped and repainted and stored away.  The G11 will be holding this scope  Inside looks like new with all the guts and gears.
