This legacy v2 kit motorises the primary-mirror focusing mechanism of a Celestron C11 SCT. Its geared stepper motor drives the focuser through a timing belt, allowing the motor to sit away from equipment behind the telescope.
The motor uses 120:1 reduction with a nominal output step of 0.0625°. Published ratings are 12 V DC and 0.27 A. The motor, SCT adapter, pulley and belt together weigh 300 g.
This version uses a 22 mm pulley bore and M3 × 30 mm telescope fixing bolts. The kit contains the motor, anodised aluminium bracket, belt, pulley and bolts. Adjust the bracket position to tension the belt as described in the installation guide.
A separate compatible stepper controller is required. The motor connects through RJ45; it has no built-in USB controller. The installation guide lists DMFC, Ultimate Powerbox v1/v2 and eXternal Motor Controller. Cable inclusion differs between published package descriptions.
Manufacturer installation guide
Exact Nimax 63048 matched to legacy PEG-MFKv2-SCT11; Zero replacement motor specifications are excluded. Kit uses a 22 mm pulley bore and M3 × 30 mm telescope bolts. Manufacturer guide lists an RJ45 lead, while the supplier says an additional lead is required: cable inclusion is not promised. Bracket colours vary across seller revisions/photos; no fixed colour is asserted. Supplier selector also labels C11 & C14, but the C14-specific kit uses different bolts; this record retains the C11 configuration. RASA 11 compatibility depends on its focuser/revision and any retrofit; no blanket RASA approval is given. Unpublished enclosure dimensions are not inferred.
