I have 3 scopes and 2 mounts so I’m frequently switching out an OTA. I have 2 Pegasus Powerbox Micros that I use for camera power and dew control. The Powerboxes are attached to the scopes with Velcro so I can switch between rigs. I bought this item so I can leave 3 environmental sensors permanently attached to the scopes to aid cable management. It’s an essential accessory in my opinion and works great. I checked with Pegasus Astro before buying and they confirmed that these sensors work across their full range of Powerboxes that have a RJ12 Jack.
