iOptron developed the PowerWeight ($119) as a novel solution to the problem of bulky power packs for equatorial mounts. The PowerWeight is designed to fit on the counterweight shaft of the iEQ45 and replaces the mount’s 7-pound (3.2-kg) weight, or works as an additional counterweight when using heavier telescopes. The unit contains six heavy-duty lead-acid rechargeable battery cells and is rated for 12-volts and 8 amp-hours — enough to run your mount for an entire evening. Includes power cable and AC charger.'s New Product Showcase is a reader service featuring innovative equipment and software of interest to amateur astronomers.
