For sale is my Beloptik tri-band ERF, I have 2 so don't need this one! The ERF is 85mm in aperture, it comes in a homemade sandwich cell that gives 80mm clear aperture. The outer diameter of the cell is 120mm. It is suitable for mounting sub aperture. Included is a transmission scan that came at time of purchase. These are rare beasts - only 6 were made I believe.
Cost is £250 £5 P&P within UK, P&P worldwide based on destination.
Ruler not included!
