Haven't quite got there yet but I've got the 'Barlow' idea with my scopes. I picked up a 2" 2 x Barlow which should give 1428 on the Lunt and 2500 on the Newt. I figured that with a 2" barlow I'd only be using the middle part of the lens so reducing the coma effect.
Ob is just coming back online after the damage rebuild so hopefully will be able to test the theory out soon.
