Posted 26 June 2022 - 11:38 PM

As a child in the ‘70’s, I wondered at owning a proper telescope after listening to my grandfathers celestial Greek myths and his telling of old astronomers  and a subsequent wonderful lesson at school on astronomy. I devoured science and astronomy books thereafter, building simple refractors following Galileo’s experiences out of surplus optics from the local optician -They weren’t good ones, but fortunately good enough to discern craters on the moon, and a little oval shaped object as well as a fuzzy Zeus and its moons. Just like Galileo had seen

 

One day I received a post addressed to me!
It contained a brand new 60mm scope beautifully boxed which was to become my most precious possession- it opened my eyes - I literally had a gob smacked expression for months. My mother would joke the wind had changed on me, and in fact it had. The things I saw that at that time I felt no one was seeing!

 

Of course, there was a little handbook we all know that came with the scope, ‘Worlds Beyond’, – In it, was my little 60mm refractor !
That scope and indeed that little book became my passage to the Cosmos. I absorbed all information I could and the sights I was gifted. I was perpetually eager and excited, rushing home every night, despite my friends beckoning, just to spend time under those hazy street lit suburban skies. It was a wonderful time and a magical experience that will never be forgotten.

 

I was forever altered and felt truly privileged.

 

I still have that little scope, and every time I open that box just to check in on that old friend, those young feelings come back. Worlds Beyond is still with my friend, always cradled beside.

 

But the most beautiful instrument those young eyes had seen was a picture in the book of a 108mm pedestalled telescope, on page 20 right next to that 60mm (labelled as a 76mm). Never in my young mind did it ever occur to me to own one. Want was certainly overwhelmed by impossibility. Nevertheless I would be transfixed by the image and funnily, and I don’t know how I came to think of this – but I would wonder if I was tall enough to reach the eyepiece  !!

 

Another book that came to me in time was Terry Maloney’s 'Telescopes How to Choose and Use Them'. From within those pages complemented by a showroom display in the city, grew another desire … Unitrons – (Polarex in Australia). The photos were a marketing miracle – every angle was glamour..  And yes I have come to own some of those scopes depicted in those pages much later in my life … BUT gracing page 4 ( see below image) of that 1968 publication and to my surprise …was that 108mm -only this time a line illustration of the same. This Tasco 20TE or a.k.a. Royal Astro R-102- always seemed to me a depiction of the perfect scope, to tease and to dream of-  but did it really exist?

 

Fast forward many years – and after seeing Mike and Alberts actual scopes on the forum, as well as other submissions on the web, owning one was now almost a  possibility –albeit a very remote one. Well ......suffice to say, I now have one! -

 

It has been living in Australia for the last 5 years, I think. I don’t know the details on how it got here but it’s Alberts scope!! – I recognised it immediately – It had been advertised for an incredibly large sum but was subsequently significantly price dropped,  but alas still gravely out of my range of affordability and practicality – However I grasped the opportunity,  spoke to my wife, (pleaded in fact), negotiated a win win with the seller, journeyed  over 1500 km ( with my lovely wife!)  and for the past 3 months I have been restoring the scope-

 

Its condition …
well, time unfortunately had not been all that good to it.
It was well used after all, and I have its published history and use by virtue of the last owner preserving Alberts information and also what has been shared in the forum.  Its a complete scope as far as I am aware less the original 50mm f10 guide scope for which I am still searching, but it has a replacement which I believe is doing the original justice.

 

Regarding its restoration…Many would argue that I may have erased its history – but it needed to be restored.
Holes and dents in the tube everywhere due to aftermarket additional tube weights and brackets, guide scopes and finders, weighting the scope and distorting the tube considerably. Not to mention heavy bumps and scuffs down to the metal.  The paint on the majestic tube was so significantly chipped and scraped that corrosion was evident, There was also a significant tube shear/tear behind the 30mm finder bracket base, a result of a strong and sharp fall on the finder mount causing the tube to dent and tear and a setting screw to be permanently imprinted on the finder metal as a consequence. The injury was bad and the finder base had to be crudely levelled by wedging a coin between the base and the tube to render it useable.  The dew shield was also chipped and dented in some places but fared better than the rest of the OTA .

 

However, over the past three months everything has been measured, aligned, welded and fully repaired and the tube  looks and works wonderfully –It has been painted with Dulux Vivid white epoxy enamel, color matched to my original Royal Astro branded 76mm scope of the same period. I swore I would not use this paint again due to the long drying times – but I have used this paint on another project, and it has proven to be resilient, scratch and chip resistant –I have also worked out the trick to reduce cure times – It is also mistake resistant.  As it takes longer to touch dry, runs or imperfections have time to blend in and disappear compared to faster drying paints

 

The scope is huge and heavy, It is imposing and it does overwhelm the Unitron /Polarex 102mm but more detail on any comparisons later
   
Its performance

After collimation and resetting of the lens- it is  amazing- I have been reading some notes on the scope in the forums and I know that many have noted or assumed the lens was made by Carton but I think I may have information that may dispel that- I may be wrong . The tolerances, identified after dismantling the tube and its components, are tight and it has been well engineered – the focuser needed work as a tooth was missing from the pinion, but has been repaired. However one thing is sure - the pedigree of engineering is exact to the other Royal Astro’s I own

 

The mount is also huge, its larger than the 76mm which uses a mount the same as the Sears 6345  (a scope which I sadly sold) and about the same size as the Polarex.  However I have to say its not 100% stable and could be due to the triangle of detachable rollers under each pod,  but it seems sufficient for the scope – Not Surprisingly the mount also  needs to be restored as it is missing large chunks of enamel, and the metal in places is exhibiting some minor corrosion
However that’s the next project

 

In the meantime its been another wonderful experience and something I can’t really articulate well– to own a piece of history and an instrument that for me has been admired almost as if a piece of art, to know that many eyes may have also felt the same. An instrument that God willing I may be able to use for quite a few years, maybe decades and then later to hopefully pass down to the more discerning future generation of enquiring eyes and hearts

 

I again feel altered and privileged for the second time

"Worlds Beyond" was an extraordinary effort by Tasco to publicise astronomy. I guess it was translated into a multitude of foreign languages and you can see excerpts from both the US and german edition pictured below. Back in the 1980´s I could only dream of a Tasco 20TE but that little booklet started my lifelong passion for telescopes and astronomy in general. To this day I haven´t seen a Tasco 20TE being offered in the german marketplace. Factory new price was 5-figure. Unobtainium for a young lad like me.

Thank you for this lovely post about your astronomy journey. It’s pretty often that I see the cover image of “Worlds Beyond” and it always instantly takes me back 50 years to when I sat on the floor of my bedroom with a copy that came with my 60mm Tasco and dreamed of planets, stars, and galaxies. I loved that scope even though the views were not very good.

Thanks for all your likes and responses

 

Here is a photo minus the tube weights which I have set aside as they are not really needed and just add unnecessary weight.

As you can probably gauge It's huge - I have 10 foot ceilings !

 

You will note the non original Guidescope and the counterweights

these are being sought - I have the option of having counter weights made - but we'll see 

 

Mount restoration to be started next month 

 

I also have to figure out how I can reverse  the polarity of the motor for Southern skies ??

goodness me.  what a magnificent machine.

 

can you tell me how high the pier is to the base of the mount?

 

also, what are the specs on that guidescope?  it looks like a 50 x 500 perhaps?

Hi Semlin 

It is indeed magnificent isn't it !

 

the pier is 1470 mm from the bottom to the top end where the silver part ends and the black base begins 

The guidescope is a Tasco made by Towa 50mm X 600mm F12 - its a lovely scope, optically seems excellent - I did reset the lens as well and welded all mounting holes closed and repainted it the same as the main tube and finder - If I find the original for this scope I will let it go - 

 

I hope this helps 

All my best 

 

Steve

it does, thanks.

 

i am in the process of setting up a pier for my refractors. a 4" f15 is as large as anything i am likely to ever put up there so that is important intel.

 

and i love the idea of a 66te being put to work as a finder.  nice job on the resto-mod.

That has to be the absolute coolest looking consumer grade Japanese refractor ever made! I am smitten every time I see a picture of one!

It does guidescope indeed looks perfect! Wasn’t the original guidescope also a 50mm x 600mm?

Great restoration job! That’s the kind of scope that will draw a huge crowd at an outreach event. It just shouts, “I’m a REAL telescope! You have to look through me!”

Never seen a real one in the flesh. Sure has to be a rare bird. I wonder how the mount compares to a  Unitron  152 mount?

Wonderful telescope. There's something about a pedestal mounted classic long focus refractor. This 20TE is just magnificent. Thank you for the photos and congratulations.

Thanks guys

 

Bob thanks - it took a while to get it to the wow - I actually followed Barry Simons posts on painting and repairing on this forum - as well as Kasmos posts  https://www.cloudyni...-removal-tips/-

 

I welded all holes closed and only used the tiniest  amount of JB where I couldn't fix all unreachable dents - it took days as I welded and cooled, welded, filed  welded again   etc.. so that I wouldn't distort the tube and get the best finish- it took most evenings after work - Im pretty happy with the results - Painting was great but I managed to get some minor dust spots- I might be able to polish them out later  

 

Terra I'm not sure about the original guidescope - I think the original is f10- but this one is pretty good - Again got a small widget insect landing on the paint near the focuser underneath- I felt so sorry for the creature but it was too late when I noticed, poor thing  :-( - I have left it there - 

 

Thanks Chip  - it would be a task to get it out to an event,  I would say.

 

Chas - I do plan on performing some comparisons with the Polarex/Unitron soon and will post  - 

 

And thanks Oldmanastro :-)

I agree its a spectacular scope. I have never seen or even heard of one here in the UK. In fact we pretty much never see anything higher up the scale than the 7TE-5 or the occasional Tasco 15K - most of the Towa 339's are found under different brands here.

 

I would love to get my hands on a 10TE-5 and compare it to my Nikon 80

Thanks Ian - I am absolutely sure your Nikon 80 is superb !

 

To be precise these never got to Australia either - The scope was actually in Canada then I believe a member, Albert,  purchased it and had it in the US and then sold it to a fellow in NSW Australia- How it got here to Oz given the sheer size and weight of the instrument, is beyond me  

The clock drive is permanently set to Northern skies so it useless here - no idea how I will reverse it 

 

Before I contacted the seller I did in fact contact Albert to ensure the ad' I had seen wasn't fraud -That was before I spoke to my wife :-) 

 

You can see the scope as it was here  https://www.cloudyni...sky-tasco-20te/

Albert kept a meticulous record of its history helped along by Mike Cee as you will note in the post   

 

I have most of what you see in that post but not all, as some items may have been lost - And I certainly have the collateral of its history that the last seller preserved - 

 

As mentioned I decided to restore the tube as it was not well- there was tear damage - and the additional aftermarket items added to the tube had also caused additional and significant damage, probably exacerbated by its transit ???

Not surprisingly the added accessories rendered the scope, way too oversized and heavy for the mount- so overall the decision wasn't hard 

 

As mentioned I may be criticised  for erasing its history - but I still have its life story :-)

Some synchronous motors can be rewired to run in the opposite direction. I don't know if this is one of then, but there are threads on CN about how to do that.

Dumb me, I figured you could just reverse the polarity and it would run in the opposite direction on any simple motor without a controller. I remember doing that as an experiment in school or home long ago with no problem. What is special about these ‘synchronous’ motors Chip? I’ve never messed with one, (probably a good thing ;) ).

well if it is canadian, i want it back!  

 

here are some reference pictures of the 20te.  the first is from a 1964 canadian tasco catalogue.  second from a 1970 and 1968 royal astro catalogues, where it was the r102.
