No longer have an Esprit, so I have a spare Morris Engraving (UK) solid acrylic laser cut f/5 focus mask. Condition is as-new.

Morris' Bahtinovs are VERY precise - MUCH more so than the dinky Farpoint etc. These are all custom laser cut for each scope dewshield diameter and focal ratio. Of course it'll work in any other similarly sized scope, but the spacing for the dewshield pegs may need to be altered so the pattern is centred.

Price new is around $45 posted from the UK. I'll sell mine for $25 posted. The nylon dewshield pegs and cord are included.
