It just occurred to me that Skywatcher Newtonians[dobs] have an unusual
focuser/eyepiece adaptor set up, and maybe you are using it wrongly, or not all the parts are there. There is a large black collar about 60mm long with a bevelled end and an opening for a 2" diameter eyepiece at the other end.
This is not used with the 1.25" diameter eyepieces that come standard with the scope. There is a plate with a bevelled side and a short tube for the
eyepiece on the other side. This plate fits directly into the focuser opening,
and is secured by the chrome screws on the side of the focuser. If you are
using the set up wrongly you will not be able to come even close to focus.
