The 10Micron GM1000 Half Pillar accessory is important if you require more clearance between the tripod/pillar and your telescope in order to avoid the risk of collision. This is especially the case with longer optical tube assemblies.
The (usable) height of this half pillar is 130mm and offers great rigidity for its weight. The half pillar is CNC milled from a solid block of aluminium, and is anodised with a black matte finish.
The Half pillar for the GM1000 HPS Mount can be used with the 10Micron Aries, Hercules and Centaurus (with the adapter) tripods.
