NGF-SE + F6.3FR


It's possible to attach a JMI focuser directly to the OTA using the R/C body and the small format SCT adapter.
This arrangement allows the R/C to be placed up to about 30mm closer to the focal plane. This is useful for
maintaining the R/C at the correct spacing from the rear of the OTA and from the focal plane of the imager.
