If the long bolts are pulled tight to compress the pillar tube then they are probably not you culprit. The joints between the legs and the hub is highly suspect. Try tightening the leg pivots to very snug. If that works you will need something like wing nuts for field use. With a column that tall the setup will never be as stiff as it once could be.

Bruce

Hi Bruce, 

Thanks for the suggestion, I'll snug up the leg pivots a little more.

I originally considered making the tripod legs longer, but I stuck the pier/column  since that was what the mount originally set on  (per Allyn Thompson's book Making Your Own Telescope). Also my observing site is small and the footprint of this combination fits the best.

Say WHAT???  THAT is Krylon??  You must have the technique down.  Looks like it's sprayed from a gun.

Yup ! .....That's Rattle Can for sure coolnod.gif . " This is how we do it  " dancey.gif ......I put the Rattle  can in a bucket of Hot water after well shaken for a few minutes . Then place the tube horizontally over a piece of 1.5 " PVC tubing AXLE . Then spray paint downward onto object tube 12-14 " away from one end to the other then back over to starting end again ( non stop end to end ) . Then rotate PVC AXLE to advance object tube for next pass . Repeat above process till covered . This process helps me control the ability to prevent Runs and Sags in the finish . The warmed up paint seems to flow and gloss to a shinier finish .

Thanks for the tip and technique Tom.  Going to have to try 5he hot water trick next time.  I still have to repaint the pier for the RVC-6N so I’ll do it for that for sure.

Adding a Finder & Bracket to a C90 Spotter:

 

C90 BT Spotter S11 (Finder Install).jpg

 

My vintage black C90 Spotter didn't have a finderscope, or any way to mount one -- no threaded holes.  I tried double-sided tape and velcro, but the tiny 8x20 CI unit kept falling off.  So I took time this morning to drill & tap 2 holes.  Took some careful measuring!  And, as you can see, the primary mirror needed a de-fogging & cleaning anyway.

 

C90 BT Spotter S12 (Finder Install).jpg

 

After installing the bracket, I gave the mirror a good cleaning.  Then, I used a Q-Tip to apply a thick layer of chalkboard black paint to the screw holes, and to some bright spots a previous owner made while cleaning the optics.

 

C90 BT Spotter S13 (Finder Install).jpg

 

Deep Purple, man!!  But no more smoke on the water silver.  While it was apart, I went ahead and cleaned the corrector, secondary, and long focus tube interior.

 

C90 BT Spotter S14 (Finder Install).jpg

 

Buttoning-up is a snap.  The two halves thread together.

"Missing Dew Shield" yes ouch, what will you do? what will you do?

Here I made a new one, but it would not fit on the male surface so I expanded it with a hammer and dolly

making it larger by squishing the molecules outward for a nice snug fit.

Frenchie is inspecting the surface just before paint making sure I got all the hammer marks out.

Not a bad view out the front window there.... is that a lake or did it just rain a bunch?

This C90 is pretty good -- lunar/planetary similar to my old Mayflower 814 (Yamamoto), but better / brighter on extended objects.  M42 was nice, and it did remarkably well on M81/82.  I'll probably crack it open again to flock the interior.

 

I bet the fogging was my fault.  I left it in the shed during our long hot summer.  I have 3 identical rugged hard plastic cases, and the C90's got behind a box -- overlooked when I brought the others indoors.

 

This is another small scope I'll use on the Mizar AR-1.  Eventually it'll go to one of the grandkids, which is why I put a correct (terrestrial) image finder on it -- makes a good daytime spotter, too.

Flood water from the mountains in the photo, mostly snow melt and heavy rains in the winter.

It fills the valley in front of my house.

I always thought if I wanted to sell my house I'd build a dock and park a ski boat out there on my

little corner over there. My NE corner is on that side of the road and about enough land for a 

lemonade stand. The road is on my land, how the county ever got away with that I don't know.

My house just turned 100 this year.

Mine does 185x with no problems. It's better than any ETX I've had, and I've had several good ones.

IIRC, I got good views of Jupiter in mine with a spectros PL7.5 @ 167x.  It came with a decent Vixen .965" prism diagonal, which is fine for low to mid power, but my Swift is better, and my Goto is much better.

Back in Message 3877 I showed a picture of my focuser modification.  It seems my tap was not real sharp and the knurled screws had some play if they were not snugged down.  So I took a ball point pen apart and trimmed the spring and each screw has pressure on it now.  Not a major mod but it

might find uses with other old focusers.  

I really like to read and learn tips and techniques from other posts.

It took years of back & forth billable hours, but I finally settled The Scope Case:

 

3 G&Gs in Cases S03.jpg 3 G&Gs in Cases S04 (FC-50).jpg 3 G&Gs in Cases S04 (C90).jpg 3 G&Gs in Cases S04 (RFT-80).jpg

 

I don't know if Bill @ Telescope Warehouse is still selling these Meade rugged cases, but they were a very good buy when I got mine.  They are air, dust, & water tight, and "bounce" rather than break -- a necessary feature for this old guy fumbling around late at night.  Each one came with a padded insert that you can cut & fit as needed.

 

I wound up out in the shed for 3+ hours...  After I got the cases configured, I noticed the C90 & RFT-80 dovetails were loose...  CUE BB's recurring Dovetail Rant:  What is wrong with these dovetail makers??  They thread the 1/4-20 holes; and, they don't widen the hole bottom so that screw heads are recessed & flush.  Makes no sense.  So, I have to stop what I'm doing, bore out the threads, and create a recess on each bar.  The only professional-grade dovetail I have is the 20" long one that I ordered from that guy in Kentucky.  The holes are exactly where I ordered, unthreaded, and the recesses are wide enough for a socket-head to fit in for tightening the bolts.  Perfect!  RANT OVER

 

BIF:  Sheldon (MASILMW) makes & sells pairs of machined aluminum dovetail bases that convert these old mounts to a modern standard -- like my Polaris mounts.  They're self-seating:  As you tighten the thumbscrew, the dovetail settles in securely to the base.  I've yet to have a scope wiggle loose with these -- can't say that about some other hardware...

So these are just some thoughts today of what I will be working on.

 

Just in the early stages of planning, but I'm thinking of giving my Meade RG mount a 2nd life.

It's been for sale, and although lots of people have been interested, no one has jumped on it.   It's cool.

I wonder how that "reflector" mount will feel with a refractor on it.

The 10" f/7 newt rode very well on the mount, but with a 5" refractor, it won't even break a sweat.  Maybe I'll get an AT130EDT, and sell the Apogee.

 

So my thoughts are how will that shiny mount look on a wood tripod?  I don't know yet how the tripods I've already made will handle the extra weight.  Hmmm, maybe I'll just make a more robust version. 

I'll make a new thread when I do . . . the wheels are turning.

The Meade SF's don't like it -- at all.  If you listen carefully, you can hear the drive clicking a Morse Code message.  Since this is a family forum, I can't post the text...

 

I'd still be out in the shed, but those injections make me woozie...  I got the dovetails fixed, then noticed some mold spots on my RFT-80.  Naturally, I had to remove those.  Then, I noticed dust & pollen on my Baader prism, so I had to clean it.  Then, I started checking my other prisms, and wound up cleaning ALL of my diagonals -- 2", 1.25", & .965" (and that's a ton of glass!).  When I finished with the Swift diagonal, I looked over at my always ready, always delivers Model 838...  Thought, It looks dumb with that Vixen 1.25" adapter & big honkin' diagonal...  Took me 10 minutes of digging to find its original .965" adapter, but now it looks as God intended.  The Swift is just behind my Goto prism, and just ahead of my Royal & Vixen prisms for image quality.

 

Still haven't found the Celestron/Vixen prism that came with my C90, but ain't no way I'm going back out to that shed!!

Next Up ! ........ Something on a little LARGER scale !  Not sure yet , but I think this very well could be original " Green Tinted " silver hamertone finish . Will post mirror engravings in the Cave registry later  , Jon . The scope is in good overall condition . In an effort to maintain the scopes good overall originality , it will receive just some Good Ole TLC  only .
