The "ST" version of the SpaceProbe 130 is a more compact version of the standard model. The ST's optical tube measures 24" long compared to 33" on the standard 130. The focal length of the ST's 130mm (5.1") primary mirror is 650mm (f/5), yielding a wider field of view and brighter images for a given telescope eyepiece focal length. The telescope comes on an EQ-2 equatorial mount with dual setting circles and slow-motion hand controls. An optional EQ-2M or AstroTrack electronic drive can be added for automatic tracking.
