Pegasus Astro Pocket Powerbox Review

Pegasus Astro Pocket Powerbox

In an effort to get a better hand on my cables, I picked up a Pegasus Astro Pocket Powerbox in the summer of 2019. The box is mounted to the Celestron 8″ SCT, and supplies most of my power needs for the main imaging rig.

The Powerbox has the additional benefit of two dew heaters. Although I’ve used the Celestron dew shield for the past few years, which had the additional benefit of blocking out any stray light sources. This allowed me to remove that extra weight on the front of my scope.
