I have a nice Micromega grain focuser for sale. This is easily the best grain focuser you can buy. Selling because I'm going to be doing mostly contact prints for the foreseeable future. This focuser works perfectly and smoothly. There's some paint wear and small dings from normal use and some fine cleaning scratches on the mirror which have no effect on use of the focuser. You can easily buy a replacement mirror from B&H for $20 if that kind of thing keeps you up at night. B&H sells the same model as the Peak Model I for $260.
$95 net to me
