Description
- This APO adopts extreme extinction measures; there are multiple light barriers inside the focusing seat and the inner wall of the lens barrel; and 4 extinction barriers are designed to meet the ultimate pursuit of extinction
- The focusing seat is made of magnesium alloy material; which can reduce the weight by more than 20% compared with the aluminum alloy material of the same specification; reduce the load and make it easy to carry
- 180mm dovetail plate; hollow design; easy to operate; easy to set; make your choice of accessories more diverse; and make the telescope more stable
- The package of SV209 is equipped with an M63 extension tube and an M48 adapter ring to ensure that the back focal length of the flat field mirror is the astronomical conventional 55mm length
- The effective field of view of the 45mm large target surface supports not only half-frame cameras; but also full-frame cameras
