デルタTヒーター

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.

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.

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.
