How to make pictures using your DSLR on PST. Using my D60 it's difficult to make prime focus pictures on the PST40. That's why I changed strategy and take pictures afocal using zoomlens 8-24mm with 24mm zooom. In order to bring the sun's surface into focus I need about 53mm to bridge. For that I need to install some spacers and finally the Nikon T-ring.
