This 12" APM Super ED apo (triplet) is actually the largest APM Super ED apo that is sometimes manufactured.
Note: We would endeavour to comply with any special customer requests during the construction of such a large apo. The delivery time for such large APM apo instruments is around 18 to 24 months.
The dew shield, as well as the OTA are manufactured from Kruppax 50, all other parts are made from CNC machined or milled high-grade aluminum. The OTA and dew shield are painted in RAL 9001 cream-white and the aluminum parts matt black. The dew shield is screwed in place and can be retracted to make the telescope shorter for transport and also has an interior baffle at the front which effectively suppresses the formation of dew on the telescope for long periods.
The 3.5" focuser works with adjustable high-precision rack-and-pinion system. There is a 50mm quick-release finder bracket on the focuser itself which is so precisely engineered that the finder scope remains accurately adjusted even after repeated removal and insertion. The focuser has a 3.5"/2" adapter at the end with an encircling clamp as well as 2"-1.25" adapter with brass compression ring clamp. The complete focuser with finder bracket can be rotated through 360° so that the finder scope can always be in the most convenient position for you, the attached and focused 35mm or medium-format camera can be rotated into the desired position, and also that you do not have to remove the star diagonal plus eyepiece when you change to observing an object at a different position in the night sky but only have to rotate the focuser. The rotation and the focuser can be locked in place with a screw.
The tube ring clamps are made of black powder-coated CNC machined aluminium and are flat on both sides with a central 1/4-20 inch thread and 2 1/4-20 inch external threads of 2.362 inch, as well as 2 threads with a 3.2" inch hole spacing (Astrophysics standard).
