Not off to a good start…..

Received the telescope , no, nada, missing instruction manuals at all ( would be nice to have IOptron state which primary mirror screws are to hold or to move the mirrors, general info on the focuser- never used a Crayford, there is a learning curve) scope was , as expected way off on collimation, collimated it, went to dark skies and found it impossible to focus on anything. Added a 2” extender, still no focus, ordered a 4” extender and am hoping for the best using it. Will update . Another pain is that it is shipped from the factory, making a return akin to jumping through hoops, pointlessly.
