I am selling my 2" Baader Semi Apo filter to help fund my ultimate scope, (well there are two) either a 10" SCT or a 12" RC
The primary function of this Filter is to provide APO type views from an Achro, the Filter dramatically reduces the cursed "blue fringe" of AChro's.
The 2" Filter is in great order and condition and is supplied in it's original Baader case. This filter makes for WONDERFUL Mars viewing!
