This Coma Corrector was only occassionally used and is in good condition. It comes with the orginal box, although the end caps that I am supplying are not the originals.
I suspect that this originally came with with an 1.25" adaptor, but I am unable to find it.
A few cautions: Coma correctors are only usefully on Newtonian reflectors. Futhermore, some have had to fiddle with extension tubes to obtain foscus.
