I have an Antares 8x50 finder 90° errect & correct image. The original 27mm Kellner eyepiece it came with was JUNK so I replaced it with a 25mm reticle eyepiece frorm Lumicon. The finder also comes with mounting rings and dovetail plate. This is a very nice finder package especially for DOBs and is less than a year old. I have moved onto DSCs so I no longer need it.
The only slight defect is that the crosshairs in the Lumicon eyepiece have been hit so it is a little off. The crosshairs are mounted on a removalble cylinder that threads into the eyepiece. This cylinder can be removed and the crosshairs can be repaired or replaced if you want. To me they are staright enough and not worth the effort. This is a well constructed crosshair eyepiece that costs over $60 from Lumicon.
This package with shipping cost me almost $200 new. I'm selling the whole thing for $95 and that includes shipping in the CUSA.
