COMPLETE WITH SOLIDMAHOGANY FIELD TRIPOD, PLUS ASSESSORIES.CIRCA 1910

FANTASTIC ANTIQUE BROADHURST CLARKSON BRASS 4 INCH REFRACTING TELESCOPE, THISBEAUTIFUL INSTRUMENT IS CONSTRUCTED OF BRASS, THE MAIN BODY/TUBE HAS A BLACK COATING AND IS FITTED WITH A RACK AND PINION TYPE FOCUSINGMECHANISM, FURTHER FOCUS ADJUSTMENT IS OBTAINED BY THE EYEPIECE TUBE EXTENSION,THE ACHROMATIC OBJECTIVE LENS IS HOUSED IN A REMOVABLE BRASS CELL. NOTEABLE WITH THE LENS HOUSING IS THAT IT HAS ADJUSTMENT FOR LENS PITCH WHICH IS DONE WITH THREE EQUALLY SPACED SCREWS. AT THE OTHER END OF THE SCOPE IS THE BRASS EYEPIECE EXTENSION HOUSING WITH THE ENGRAVED DESIGNATION: “BROADHURST CLARKSON &Co., 63 FARRINGDON Rd., LONDON, E.C. THE TELESCOPE IS CONFIGURED AS AN ASTRONOMICAL REFRACTOR BUT ON THE TUBE BODY THERE IS A MILITARY “CROWS FOOT” MARK SO POSSIBLY COMMISIONED BY THE ARMY? THE FIELD TRIPOD WOULD SUGGEST THAT! IT IS HUGE AND VERY SOLIDLY CONSTRUCTED WITH THREE LONG MAHOGONY LEGS, EACH WITH A BRASS POINTED END CAP. A VERY HEAVY STEEL FORK SITS ATOP THE TRIPOD ON A HEAVY BRASS SWIVEL YOKE, ALLOWING FOR SMOOTH 360 DEGREE HORIZONTAL MOVEMENT AND VERTICAL MOTION.

THIS HUGE TELESCOPE IS BEAUTIFUL TO BEHOLD AND IS IN FULLWORKING ORDER. THE OBJECTIVE LENS IS BRIGHT AND CLEAR GIVING QUITE STUNNINGVIEWS OF THE NIGHT SKY. I PERSONALLY OBSERVED SATURN AND HER RINGS DURING EARLY JULY AND IS ALSO FANTASTIC FOR VIEWING TERRESTRIAL OBJECTS GIVING SPECTACULAR CLOSE-UPS, ALBEIT UPSIDE DOWN!

CONDITION: THE MAIN BRASS TELESCOPE BODY HASA FEW EXPECTED DINGS TO THE TUBE WITH SURFACE MARKS, SCRATCHES AND PITTING. THE BLACK COATING HAS PROBABLY BEEN TOUCHED UP OR REDONE OVER THE PAST HUNDRED YEARS OR SO BUT IT STILL LOOKS GREAT. THE OBJECTIVE LENS APPEARS TO BE INSUPER FINE CONDITION WITH NO APARENT ABRASSIONS, CHIPS OR CRACKS, IT LOOKSCLEAN, FOG FREE AND BRIGHT, THE OBSERVATIONS I HAD BEING TESTAMENT TO THAT. THE FOCUSING MECHANISM WORKS FINE AND IS REASONABLY SMOOTHTO OPERATE.THE BLACK FORK MOUNT HAS ADJUSTABLE BRASS BARS WITH TENSIONERSWHICH WORK VERY WELL WHEN KEEPING THE TELESCOPE TIGHT AND STEADY WHEN FOCUSINGETC., THE FORK MOUNT PROVIDES FOR SMOOTH HORIZONTAL AND VERTICAL MOVEMENT OFTHE SCOPE. THE BEAUTIFUL LONG MAHHOGANY LEGS LOOK FABULOUS IN A HIGHLY POLISHED BEESWAX FINISH. THEY EACH HAVE A POLISHED BRASS CONE SHAPED TOE.

19th Century Bardou Library Telescope

Posted on September 3, 2017 by

If you buy after clicking affiliate links on this site we might receive a commission from companies such as eBay, Amazon etc This does not affect the price you pay.

19th Century Bardou Library Telescope, made of brass and on a cast iron table top stand.

The optics are clean and in excellent condition, the telescope gives bright and sharp views, please note that

this is an astronomical telescope and the image through the eyepiece is therefore inverted. The telescope has

taken a few knocks over the last 150 years and therefore does have half dozen small dents and scratches to the

main tube, I think these just add to its charm. The long focus draw tube fits well and slides in and out nicely, the

rack and pinion fine focus mechanism does work effectively but is a little rough.

The overall length of the main tube in 38” and in addition the focus tube adds another 6”.

The objective lens is 3” in diameter.

A good looking and functional antique telescope by a well known French maker.
