The basic means of photography through
ETX-60AT or ETX-70AT telescopes.
A T-Ring (available separately) for your brand of 35mm SLR camera is also required.
Flip the telescope's internal mirror to the straight-through position and thread the 64ST and optional T-ring on to join your telescope and camera. The telescope thus becomes a 350mm telephoto lens for photography of the Moon, planets, or terrestrial objects.
