TPS

Hi all 

thanks for all the replies. 
the issue was with the setup. All sorted now and focusing correctly.  Bit of an ID10T error. 

Thanks all.   
yes I meant eyepiece.  

black spot was centred on the object but iPhone picture made it look off centre. 

problem was indeed with focus. I believe this is now corrected.  Waiting for return if clear skies to be sure.  
 

many thanks all. 

Hi all.  Complete newbie here. 
I have an intes mk-67 catadioptric telescope and was looking to set it up for the first time. When looking at a bright star I see a black circle over the centre of the star. Moving the scope slightly the black circle follows the object. Is this an adjustment issue with the scope or something more serious.
