SkyWatcher Black Diamond 300 1200 DUAL SPEED SkyWatcher Reflector Tube

SkyWatcher Black Diamond 300 1200 DUAL SPEED SkyWatcher Reflector Tube.

The new SKYWATCHER 300 1200 OTAW DUAL SPEED tube incorporates a superb set of mirrors along with two very important features: a Crayford DUAL SPEED focuser with a 10:1 ratio that allows for excellent and accurate focusing.

Another important feature of the SKYWATCHER 300 1200 OTAW DUAL SPEED tube is the fact that it has a slightly shorter length than normal to improve the performance of the equipment when performing prime focus astrophotography. Its performance can be greatly improved with a coma corrector such as the BAADER PLANETARIUM MPCC .
