The RV6 has me feeling a lot more confident about my ability to paint things - and one of the guys in WAS who did my '72 Tricolor at his auto body shop is always around if I can't do it.

Yes, I'm getting it - got to figure out what to do for rings. Seems those don't show up often.

 

Should be fun to play around with. Keeping either it or the RV6 for outreach, one has to go.

Great! Congratulations. I’ve always loved Caves.

Thank you! I've always wanted to at least try one out. Seems not many made it to the East Coast, and when they do, they're all cleaned up and well over $1k.

That model did not come with rings, just metal straps with a felt-lined inside.  It had a 1/4" threaded rod that was slotted and welded to the strap for tension.  The other end was secured with a 10-24 screw I believe.  It you would like, I could send you some photos of mine.

That would be great. What should I use to replace the straps?

Looks too short to be an 80 f15, I wonder if it’s the f12.5, maybe the triplet.

Picked up a cheap Mizar (Meade) EQ mount and 60mm f/15 scope.  The scope is nothing to write home about - plastic tube and objective cell, but the focuser (which is also plastic) will accept the vixen 1 1/4" visual back.  My initial views through it were very positive; it looks well collimated and nice round out of focus star images at high power.  But I really didn't care about the scope - I wanted the mount.

 

I've read good things about these Mizar mounts and for $50 I couldn't pass it up.  It was in very good shape but the grease in both axes was a bit stiff.  A drop or two of mineral spirits softened it up nicely.   I had to fashion an adapter out of some leftover poplar so I could attach a vixen dovetail clamp to the mount - the screw holes don't match up.   If I end up really liking the mount so that it becomes the new grab & go setup, I'll fashion a more robust adapter out of aluminum.

Tonight I have the Sears 6339a on the mount in the backyard to see how it works out.  The mount only came with a single, thin counterweight, so I had to scavenge a weight from another scope - it doesn't quite fit the shaft but it works.  I get the impression that Mizar counterweights are hard to come by.

Thanks to everyone for help and suggestions - I'm picking the scope up this weekend and look forward to refurbishing.  

Are there any general guidelines/references for overall scope refurbishing?

Errrm,,,,, It's an air spaced objective....

 

What i thought was a clam still looks like a clam, shouldn't be a problem as for most observing it'll be in the outer 20% ish' of view. the rest should clean up nicely albeit with some coating loss which isn't that important. Most of what looks bad will wash off, the four noticeable black dots may have etched but you won't know til it's clean.

 

Let the lenses sit in some lukewarm water with a touch of dish soap, dont rub them!!! rinse with clean water. There's a ton of info on the internet on lens cleaning so good luck smile.gif

The strap is 0.75" wide x 0.02" thick.  The exposed 1/4" thread is 1.75" long.

Have a look through the posts here, https://www.cloudyni...t/#entry1394359   no vixen but dozens of rebuilds,

 

Alternatively, take a look in the search bar (top right) for "cleaning" there are dozens of rebuild threads in the classics section. Another way is to start a new topic with pictures of the lens taken apart out of it's cell and ask for advice. I've never had to deal with anything other than a bit of mold or surface grime that usually shifts with soapy water, Isopropol alcohol, Acetone, Cold cream(for mold), and a bit of gentle care with clean warm water and a bag of cotton balls. Here's a video of someone cleaning a lens, https://www.youtube....?v=jpe1fR_HiYI

He uses a brush where i rinse the objective with water, he uses lens tissues, i use cotton balls, same procedure just different materials. Use a fresh wool ball with soapy water for each stroke, when clean you can dry with dry wool balls, in both instances just drag the wool over the lens dont apply pressure.

Thank you! Seems like I can get a hose clamp, paint it black, rivet on a piece of threaded rod and add felt on the inside and I'm set.

An easy Find:  Terra's 1966 Edmund EQ on the restored 1960s Filotecnica Tripod, carrying my Triple Nickle 5:

Took these right after sunset, so the colors aren't quite right.  The Bronze is not that gray; and, the legs are a bit lighter & have more orange.

 

I had cleaned the legs with Murphy's.  While they were off the hub & disassembled, I brushed on linseed oil, let it set for a few minutes, then wiped & polished with cotton rags.  I'm very pleased with the results.  No need to sand & refinish them.

Testing it last night took me back to sessions with my gone - but never forgotten - 1950s Edmund 4" F15 on its original mount...  Sweeping?  With a LONG frac?  Sure!  When the mount makes it too easy - gliding along chains of stars feels as natural as using binoculars...  Too easy?  Yes!  You can forget how heavy the scope is, and how slick the axes are, and when you change eyepieces... it swings around & bops your noggin!
