Parallex Instruments Hi Grade Rings for 8" tube
High grade slip rings for newtonian telecopes
beautifully made and felt lined to avoid scratches - sturdy and yet still allows the tube to slip easily when aligning it
they measure 230-235mm internal
surplus as I dont have the tube any more
$160 AUD - free shipping from NZ
