It,s a beauy , I am sure it would sell reasnobly easily , price anywhere from $900-1500 these are a big step up from the chineese 102mm achromats and having the 114mm tube have a very good baffle system that gives very sharp and contrasty views with minimal CA .
The mount is the Vixen Great Polaris , these are a very smooth and sturdy mount , I love mine , here it is under my little 60mm triplet .
