For Sale a Vixen PH corrector for the Vixen r200ss
astrograph Newtonian. This is the top of the line corrector out of the three available for the r200ss from Vixen . Price $400 plus post
Pardon my ignorance but what is the difference between this coma corrector and the “original” vixen coma corrector 3? The latter sells for $165, is the PH corrector “worth” the extra dollars?
Thanks
Bo
