6 inch Fluorite Apochromatic Hand Crafted folded refractor
* Hand crafted optics (objective and 2 flats) by master craftsman Barry Adcock (ex President of Astronomical Society of Victoria, long term telescope builder extraordinaire)
* 152 mm Clear aperture
* f 10.5 - Focal length 1600mm (63 inches)
* Two flats mounted internally - Zerodur Zero Expansion glass - aluminised and Si O2 overcoated
* Optical flat # 1 - 120mm round
* Optical flat # 2 - 100mm round
* Full set of technical design and engineering notes from Barry Adcock included in supply
* 168mm diameter hand crafted aluminium objective cell (by Barry Adcock) including push/ pull screw collimation capability
* 2 inch rack & pinion focuser
* 9X50 finderscope
* Hand crafted wooden case (refer image)
Notes:
Barry started making refractors decades ago, he commenced making hand crafted Fluorite refractors about 9 years ago when he made a 1/100 wave fluorite for myself (I was his first hand crafted fluorite) - this is the telescope in the image on my signature, and resides in my observatory, and is exceptional. This telescope has an incredible capability, and using exotica level eyepieces has achieved in excess of 1000 magnifications on the moon on nights of exceptional seeing capability.
Barry crafted the optics for this sale item - the 6 inch folded Fluorite Apochromatic refractor - for Jacob Apfelbaum (President of the Shoalhaven Astronomical Society, Nowra, NSW) three years ago. The design of this refractor objective is identical to my unit, thereby it's optical capability & performance is directly comparable.
I purchased the Quantum Mak Cass 8 inch (in Jacob's 27 Nov 2008 Ice In Space ad) from Jacob last week, and returned the 6 inch folded hand crafted refractor with me to Melbourne to support Jacob with his sale. Enquirers are welcome to deal direct with myself or with Jacob (however if dealing direct with Jacob be kind enough to copy me).
Jacob advertised this telescope on 27 Nov 2008 on Ice In Space, please refer to his ad for details and comments from others regarding Barry Adcock's capabilities as a glass specialist.
For my part I have been fortunate to retain the services of Barry Adcock to hand craft 4 telescopes for me, these are ALL 1/20 wave PLUS capability each, and perform to a standard that is NOT available commercially.
This project represents a unique opportunity to obtain an exceptional telescope at a give away price.
The system is being sold at $ 4,000 cash rate.
This rate does not even the cost for the glass, and at that the cost at the old exchange rates of 6 months ago.
Shipment locally, nationally and internationally is available at extra cost.
Thanks for looking.
