This adapter allows you to connect the ESATTO 2" focuser to the Skywatcher 250mm f/4 & f/5 Newtonian telescopes.
The thickness is the same as the stock focuser (excluding camera adapter for the ESATTO), allowing you to easily reach prime focus. The adapter has the holes for tube installation that correspond to the original ones so it is not necessary to drill new holes in the optical tube. It also features screws for adjusting focuser's orthogonality with respect to the optical axis of the telescope in order to perfectly adjust ESATTO to your telescope. Optical thickness of the adapter is 3.5mm.
