I wanted to make sure my 350D with Baader MPCC attached would reach focus after a modification to the focuser tube on my 200mm Newt, i.e. the addition of an extra holding screw. As we have had rain I noticed the moon in a clear patch of sky just before sunset and quickly grabbed my scope and camera to check things. The MPCC gives a sharp field right across the frame so the moon looks excellent with the coma corrector attached. In past shots the centre of the image has been sharp whilst details have become progressively deformed towards the sides of images, as you would expect with a fast newtonian.
Happy to report that with the extra screw in the side of the focuser ring fitted with a self tapping stainless steel screw ( tip filed smooth ) I now have a rock solid camera attachment. No more flying camera !
