The GEM45G and CEM40G are upgraded versions of the standard GEM45 and CEM40 that include a new Dual-Saddle with integrated iGuider guide scope. The iGuider is a 30mm f/4 lens with a 1/4" CCD with 3.75 um pixels and a built-in windows driver compatible with PHD auto guide software. The CEM40G also uses the wider diameter counterweight bar common to the GEM45 and CEM70.
