Questions...
1) With Case?
2) With the Cemax eyepiece?
3) With the Manta Mount?
4) With a SM40 double stack etalon?
5) Original box? (for those who have to have it... ha ha)
6) Condition?
7) "Rust" / No "Rust"? (This is the degradation of the front objective, not real rust)...
For a list of "Sick" scopes and a good explanation...
