This pier top plate is drilled and tapped and milled for a wedge fitting an LX200 (I used a Milburn wedge) or has through holes for mounting an LX200 in Alt/Az mode.
The dimensions are 10”x11”x 3/4”. The ring is a nominal 7 3/4” and will fit inside any 8 1/4” steel tube with 1/4" walls. A direct fit for a Le Sueur Aurora Astro Pier.
When secured it is rock solid.
The new one I had built for my new mount cost me over $200 for machining and welding, $50.00 seems reasonable for this one. It is in very good condition. Buyer pays shipping.
Thank you for looking,
