Pick N Pull ! <| sep |> He sounds like a psychopath . If he was generally immature , I ' d blame in on immaturity . But if he ' s generally nice and was so calculatingly mean to you , that ' s a huge red flag . Get away from him . <| sep |> If by the adapter for 2 you mean the optical path extender , then the Zhumell needs one for 2 eyepieces as well , as far as I am aware . This is actually a case with many Newtonians that are designed with astrophotography capability in mind . It ' s because cameras usually need additional 3050 mm of optical path compared to eyepieces , so telescope manufacturers add optical path extenders instead of making longass focusers saves on materials and less of focuser tube protruding into the tube when at the shortest . Usually the 21 . 25 adapter already includes some optical path , so separate extender only needed for 2 eyepieces .
