Used for precision collimation of reflectors after basic collimation using your Site tube and Chesire eyepiece. Paid about $38 with shipping plus something for the book, but I forget exactly. Eyepiece only used a couple of times. Book is an indepth explanation of collimation by Menard & D'Auria. Book has a few creases. EP is like new. Did not come with a box. $22 including shipping CONUS. Thanks for looking.
