i have a konus 8" newtonian scope and motorised mount. a slr film camera. and im trying to take shots of saturn. but every time i take the shot it comes out blurry and looks out of focus. i expose for 1/2 second and 1/4 second. but both come out bad. the camera is connected to the scope with a eyepiece projection adaptor. ive taken shots when it is focused threw the camera. and tried focusing the scope before the camera is attached. but both don't work. any idea's?
