“Cap’n! Presents off the larboard bow!” 
“I see ’em! Ready the launch! You there – come about into the wind! We’ll not let them escape us now! Bring up the harpoons!” 

The greatest thing about collecting antiques is that you always find the best birthday presents for yourself, if you search hard enough! I picked up this stunning beauty for my birthday! Yes, I’m officially…29. Oh, the horror, shame, and disgrace of it all…!

Up Close and Personal!

Aaaaanyway… 

What we have here is an old-fashioned nautical telescope, as was used on the sailing-ships of old. And boy is it ever a monster! It’s 11in. closed, extends to 39in drawn out, and weighs a substantial 1lb 10oz (approx 750g)! A lightweight, it ain’t!

Features of Construction

This stunning antique features entirely brass construction, with the exception of the wooden sleeve around the barrel, and of course, the glass in the lenses. It is possessed of four, brass draw-tubes, as you can see in the photograph below:

All Drawn Out… 

A four-tube telescope means that it has four tubular extensions which collapse into each other, and which then all slide into the main barrel at the front of the telescope.

I’m not sure how old this telescope is, to be honest. It’s of a style that was widely manufactured from the 1700s right up to the 1900s, but the fellow I got it from believed it to be from around 1850 or 1860. For something roughly 150 years old — after extensive cleaning — it does work pretty well! The threaded brass coupling-rings hold well (or they do, after a minor adjustment), and the tubes slide in and out smoothly, if a bit more firmly than I’m used to!

The telescope has a two-piece achromatic lens at the front, a two-lens relay system inside the smallest draw-tube, and an eyepiece lens at the far end – so four (or five, depending on how you count it), lenses in all!

Here it is, next to my solid brass, pocket telescope from the 1890s. As you can see, there’s a huge size difference! 

As one would probably expect from something like this, it’s got a GREAT range, and surprisingly clear optics for a piece that’s obviously seen quite a hard life. There’s one small blemish on an interior lens which, try as I might, I couldn’t remove, but other than that – the clarity is impressive.

Using the Telescope

Since it is 150 years old, I expected the telescope to be dirty. I didn’t expect it to be THIS dirty! It required EXTENSIVE cleaning to get it to function even halfway decent! And I’m still cleaning it! But despite that, it’s beginning to show signs of the smoothness of function it once had.

To draw the telescope, I’ve found it’s best to hold it at the near end of the barrel (away from the lens) and to pull firmly, but smoothly, to get the draw tubes out, and to hold the barrel in the middle, when snapping the tubes shut again.

As I said, this telescope is quite chunky, so using it can be a bit of a challenge. I generally hold the largest, or second-largest draw-tube in order to balance this beast, and then adjust the focus by sliding the smallest draw-tube in and out, until clarity is achieved.

The good thing is that this is done relatively easily. The bad thing is that it’s surprisingly tiring on the arms! A telescope that weighs about a pound and a half doesn’t sound like much to carry around (and it isn’t), but when you’ve held it up in one hand for any length of time while trying to look through it, the weight does start to pull on your shoulders a bit! One wonders how the sailors of old ever managed to use this thing on the rocking, rolling deck of a sailing ship!

Cleaning the Telescope

The one saving grace about this telescope – and most telescopes of this design – is that they’re extraordinarily easy to clean. All the draw-tubes, lenses and coupling-rings screw together. All you need is a box of tissues, some oil, and a firm grip to screw and unscrew, and you can pull apart the entire telescope to clean it. There aren’t that many parts, and there’s no way you can confuse one part for another, so they’re very easy to put back together again.

You don’t need any special tools or equipment – just a few basic cleaning supplies and a spare afternoon. I think it’s amazing how something which is so easily assembled is at the same time, so incredibly powerful, and yet, so simply constructed. Even a child could do this. I love the thoughtfulness of the design in that the manufacturer imagined that the owner might want to disassemble his own telescope for cleaning and maintenance. I don’t know many consumer products today which are this user-friendly!

Repairing the Telescope

As much fun as this telescope is to use and to clean and polish, when I bought it, the telescope also had one significant flaw – It wouldn’t stay together.

As I said above, the telescope’s components quite literally just screw, one-into-the-other, in a set sequence of construction. Easily followed and impossible to screw up. A few good twists would be all that’d be needed to pull the thing apart, clean it, and reassemble it. Unfortunately, this wasn’t the case with this telescope.

Probably due to overzealous cleaning in the past, or possibly a manufacturing fault, or simply just 150-years’ worth of wear and tear, the thread that held in the largest draw-tube (the one which connects to the barrel) was not gripping properly. It simply refused to hold. After screwing it in as hard as possible, it’d simply pop right out again after one good pull! Hardly ideal!

I pulled the telescope apart and cleaned the threads, and then to fix this problem, I wrapped ordinary paper masking-tape around the threads on the coupling-ring. Just once.

Group Shot! My big telescope, my small telescope, and my field glasses all together. All brass, all antique. What a pretty trio they make.

I trimmed off the excess tape with a pocket-knife, and then screwed the two components back together. No oil, no graphite powder, nothing. Just a simple layer of sticky tape. It cost me literally nothing! and yet…the repair worked!

Just one layer of tape was all I needed to build up the necessary thickness, friction and ‘bite’ necessary for the threads to screw in smoothly, and for the connection to hold! it took me less than five minutes to repair. Don’t be daunted by broken antiques – sometimes all it takes is a bit of creativity to return them to full functionality.

Last but not least, here’s a short video I made about the telescope:
