Hey Tony,
I can't speak definitevely but the colour fringing that Roger and I spoke of was on NON APO, not APO gear. As far as I've read the APO's don't colour fringe at all! The scopes aren't thousands (plural) for the OTA - mine was $400 second hand and for $700 I could turn it inot a APO. At Andrew's Communications for the William Optics the 80mm APOs from Walliams are usually between $1,200 for and APO doublet to $1,439 for and APO triplet
