Samuel N. ★★★★★

Finally, no more scrambling to cover the mirrors before dew sets in. The internal heater system on this Delta T keeps the primary and secondary perfectly clear all night, even in heavy moisture. Setup was straightforward and it's been totally reliable so far.

Hazel ★★★★★

Installing the internal primary and secondary dew control was a breeze, and now I never have to worry about fogging mid-session. The Delta T keeps the optics clear even on damp nights here.

Aurora ★★★★★

After fighting with external dew heaters for years, having the Delta T built right into the CDK is a game changer. The primary and secondary mirror dew control system works silently and keeps everything clear all night long.
