I use it on my 2120 tube all the time.
Color is great!
Works very well with the F10 ratio of the scope,giving a nice wide field.
Immages are very crisp. works well in my light poluted back yard.
I love panning around with these eyepieces during the day with the binoviewer in my refractor. These are a best buy in astronomy for the money. Ill never sell my pair!
