This is the legacy geared FocusCube v2 configuration for Celestron C11. It contains its own motor controller and stepper motor, communicating directly with a computer over USB 2.0 Type-B. It is distinct from the newer FocusCube Zero.
The manufacturer’s v2 manual documents a 7.5-degree stepper with 1:120 gearing, 5755 full steps per motor-output revolution and 11510 firmware half steps. The SCT installation uses a shaped aluminium bracket, pulleys and a timing belt; the appropriate pulley and screws are selected for the telescope.
Use a 12–13.8 V DC supply capable of at least 1 A through the 2.1 mm centre-positive input. A 0.6 m RJ45 temperature probe is documented, with ±0.5 °C accuracy from −10 to +85 °C. The RJ45 socket accepts the sensor or optional hand controller: it must never be connected to an external motor-controller output.
The manual provides ASCOM, INDI and standalone software support. It specifies a 56 × 63 × 39 mm enclosure and 300 g weight. The controller is not waterproof and should be kept dry.
Pegasus Astro manufacturer documentation
Legacy v2 manual revision 1.2 selected, including its SCT bracket section. Zero motor specifications are not applied. The manual’s family pulley-bore list does not unambiguously assign all bore/screw combinations to these three store kits, so exact pulley bore and screw length are not asserted.
