Nippon Goto Kogaku 100mm Refractor Telescope
FOR SALE - Nippon Goto Kogaku 100mm Refractor Telescope
Still too many telescopes, so this classic simply has to make way to assist to support funding my new 200mm Officina Stellare RH200 astrograph
Produced in Japan during the 1960's, the Nippon Goto Kogaku telescope was the forerunner of Nikon. This achromatic design refractor telescope has a premium quality 100mm crown and flint objective lens with multi-layer coatings for excellent colour correction and image clarity. It utilizes a brass 1.25" rack and pinion focuser and has a focal length of 1500mm.
This telescope is really rare - it is the only Goto Kogaku telescope I have encountered in fifty years of astronomy. Similar to the famous Unitron's, but with significantly higher optical performance and capability - and I make this comment as a massive Unitron fan and owner of Australia's largest collection of Unitron's - so if you have been considering a 100mm Unitron - this unit is what you have been looking for - as it will outperform it.
Supply includes:
* Solid brass 1.25" focuser and assembly
* Japanese premium quality (Nippon Nikon) crown and flint objective lens
* Premium multi-layer coatings for outstanding colour correction and contrast
* f/15 focal ratio with a 14.3 limiting magnitude and 0.7 resolution
* Ultra rare collector's item telescope in good condition
* Includes original GoTo Kogaku finderscope, finderscope bracket, mounting rings and dovetail
Price $ 1,500 plus shipment via courier available nationally (at cost)
OPTIONS:
A. Eyepieces
If you are interested in adding some eyepieces to add to this system I am able to offer the following premium set:
1. Celestron Kellner K40 40mm 1.25 inch Circle T Japan
2. Celestron Kellner K25 25mm 1.25 inch Circle T Japan
3. Unitron Erfle ER20 20mm 1.25 inch Japan
4. Or 9mm Orthoscopic Circle T Japan
5. Or 6mm Orthoscopic Circle T Japan
If you want the telescope plus the full set of eyepieces I will do the 4 eyepieces for $ 180, which is way way below what they are worth. I am not prepared to sell these eyepieces separately at that price, so don't bother asking.
I am culling my eyepiece set and these are overages, and are all in very capable in performance and operation. All are original premium Japanese and are all 1.25 inch.
B. Diagonal
If you additionally want a diagonal I can assist with an original Tasuga 90 degree prism diagonal (the people that make Takahashi's diagonals) 1.25 inch prism diagonal which these were originally supplied with at say $ 100. Those that know this diagonal will know it is worth more than double this price 2nd hand, again don't ask to buy this part separately, as again I am not splitting and not selling my original Tasuga units at this time, they are far too valuable to do that.
Alternately you are welcome to a brand new (in original packaging, with full warranty) William Optics Dielectric 1.25 inch Carbon Plates diagonal at the same rate of $ 100 - which is below anyone's retail rate. Again not available separately at this price, so don't ask.
Thanks for looking.
