No matter how die-hard we are about restoration and in some cases resuscitation, surely we’ve all run across something that’s made us throw our hands up in the air, shake our heads, and say “This is ... !” Lets see ‘em. lol.gif

I haven't really owned a scope that was cosmetically that bad but I have seen optics that were...Dynamax, Jones Bird and Chinese 8" f/4 spherical disasters.

I specialize in restorations that others would just toss in the trash.  If the objective is good, nothing else is insurmountable.

 I'm remember going to  a star party and looking at a homemade Newtonian were  the elliptical diagonal was glued on 90 degrees from how it should be ie the major axis went side to side instead of up and down.

Nothing is so bad that it has no useable parts.....  well, some stuff is.....  it's more the question of 'is it worth 57 hours of my time to bring a battered el-cheapo 60 back to life?'

 

That's one I've repeatedly not-yet learned the hard way... so rule one - get it to work just enough to star-test it, then and only then, if it passes, put the time into it to fix it up.  A shiny, freshly repainted piece of dung is still.....a piece of dung.

Heh.  I apparently have a thing for basket cases as well.  You're responsible for one of them - the RVC-6N, which I replaced the optics in anyway.  As soon as I come back from vacation next month, my plan is to start wrapping that one up.  I have a lot of fasteners to order (and some taps since I'm going to rethread a number of odd sized threads).

I've never once heard my wife call one of my telescopes "a pile of junk" I've

heard her call my bicycle projects that, in fact  just this morning she called my

new bike a pile of junk and even our dog barked at it!

Not fouled up, but a big disappointment.  According to the color chart at Lowe's & the cap on the paint cans, this was not supposed to be baby blue!  It should've had more green & silver in it.

I had my fingers crossed while it was curing...  

 

The Tinsley will have a new owner soon.  I bought several cans of Rustoleum Bronze months ago, but we've yet to have a dry enough weekend for me to redo the pedestal!

Admittedly.  I have limited experience  but finding the Meade etx90 at the town dump with the tripod legs bent in half and some cement on the tube and lens cap  is as close as I have come fubarland

 

But as Chuck has  said;

"I specialize in restorations that others would just toss in the trash.  If the objective is good, nothing else is insurmountable "

 

 Donating it to Augustus was  a good move on my part as it was restored/utilized or otherwise repurposed by his skills and knowledge and he can turn it over  to move on to another project.

And I felt good doing this.....

I don't know BB, baby blue or not that's still one nice looking scope and restoration.

Thanks!  The Kicker:  It's one of my best rattle-can paint jobs -- no runs, smears, thin patches...  But.  The.  Wrong.  Color!   Just my luck.  (One reason why I no longer buy lottery tickets.)

My biggest ... let’s call it disappointment :) so far was a Meade 2080 LX3. It was not expensive and very original and complete with wedge and tripod and some old Meade eyepiece I figured I’d never use anyway. It had the Silvered optics and I knew that could mean recoating the mirrors eventually but that also wasn’t a problem on my sample.

It was just bad optics! First start test was all triangles and thought that’s okay for something unused and shipped to me ... let’s just adjust it ...
Then a really clear astigmatism showed up. Ugh, nooo ...

I ended up selling it on the cheap to a more inclined person. Kept the wedge and tripod. And I kept the unwanted eyepiece, it turned out to be a RG 20mm and it’s just a gem!

I really liked the handling and appearance of the 2080 but I’m cured, next time it has to be an orange or a post-Halley C8 if I am ready for an 8” SC again :) Thomas

The only classic Astronomical mistake I've made, and it was a big one, was to ship my Classic scopes across the world to a location which seems to have perpetual rain & cloud. foreheadslap.gif  

Should have bought a place in Chile.

My 2080 was a stinker optically as well.

It could even be a classic now my old Starsplitter 14.5" truss dob.

It was one of the early of the really high-end dobs with a fantastic NOVA primary

and a obstruction of only about 20% I had to be really careful not to snag one

of my knee caps on a crater rim while observing the moon, yes it was that

good.

Well, one day I lifted the handles a little too high and the scope slipped out of the

rocker box and crashed on it's side in front of me! and to add to the WRECKAGE

the primary came rolling out of the mirror box!

Lucky for me I caught it before it flopped over on it's front or back which would have

surley clamchipped it in a big way.

I don't have any pictures of all the scars on the beautiful apple ply, the scope is long

gone from my possession.  A BIG MISTAKE! AND A LESSON LEARNED!

 

Robert

So far only a close call.

Once while reinstalling a lens in it's cell, it got cocked and stuck pretty bad. I took a deep breath took my time and was able to get it out without any damage.

 

p.s. maybe it was a classic mistake joining this forum, as my collection and obsession has soared ever since.

This was my biggest telescope mistake, so far.  An eBay purchase, a momentary lapse of sanity.  When it arrived it didn't even have an complete objective, just the crown glass.  The tripod was an old wooden photographic one somehow converted for the telescope.  I did end up fitting a Zeiss Jena Telementor lens to the OTA and 3D printed a .965" eyepiece holder on a new brass focusing tube.  The old girl became a highly usable telescope and is  currently residing in a family with two smart young daughters who are on their way to becoming astronomers.

This is totally embarrassing, but it's got to win the Classic Mistake Award! lol.gif

 

It's my RV-6 "mounted" on a temporary mount for my 12.5" which rolled out of the shed on lawn mower wheels!!!  What a kluge!  I shudder when I see it. I can't tell you the date of this photo, but it's somewhere around 1981. I can't remember why I did this, but it must have been a "brain child" after coming home from the bar.

Not this one! It had a full thickness, 12.5” f/6.3 specially selected mirror from Coulter before they started their Dobsonians. This scope gave beautiful pinpoint stars across the entire field. I waited months for that mirror and it was worth the wait and more. I sure do miss it. I’ve seen Pluto with this scope, also the comet hitting Jupiter, and many other very memorable sights.

F/6.3 would be perfect. But them sub F/4.5 's in them days were pretty coma filled and just flat out bad most times.

I put lots of time into this one, convinced it was an Asahi-Pentax.... it wasn't.    very slight differences between focusers, but more obvious differences between whatever brand objective this had (there was no maker's mark) and an Asahi.

 

I finally gave it away.

 

Looks just like a real telescope though, doesn't it!

I see you guys have all had your share of mistakes.   I think my biggest mistake was buying to many scopes and than hanging on to them all this time.
