Nah. Theres plenty of other ways to get an object in the centre of a frame. I've got 1/2 dozen proggy's that do it for you. micrografx picture publisher is usually the one I use most..I'm not even sure if I need to do this even though I have tracking. My tracking isn't too good. I just plonk the EQ out in the back-yard, with a rough polar alignment, & adjust the DEC axis as I'm shooting to keep the object central in the LCD screen. Obviously if I was doing long exposures, this wouldn't work! Bright planets are fine though..
