Platforms by Gregg Blandin
Introducing the Crossbow EQT-150SC, a lightweight super-compact platform for telescopes weighing up 150 pounds.
Designed to be light weight, small in size and easy to use, the new EQT-150 Super-Compact is a stable mount for Dobsonian telescopes with base diameters of up to 26 and 150 pound weight. Its a miser with electrical power, providing fifteen or more hours of tracking with just 2 AAA batteries. The drive motor quietly moves the platform through its one hour plus tracking cycle. The EQT-150SC comes with a drive friction release lever for easy resetting. The platform even folds up for travelling, fitting easily into a camping chair bag.

Near the "beginning" of travel
About 5.5" high. So with the ground board removed, the "net" increase of eyepiece height at zenith is about 3".
