Does anyone know who makes custom spacers etc..
I’m after a 12mm or 15mm thick x 2” or 50.80mm internal ( at least 8 to 10mm flat faces ) for my new 8” Newt to reach focus
I fashioned one out of an old Bintel 35mm eye piece extender , it works but it’s not precise and I’m getting some micro tilt

Any advice or help much appreciated

Happy to pay associated costs and postage for 2 off , one for use and one spare

Cheers
Martin
