Dew-heater details

Hello Chris, as discussed, I am uploading the pics from the inside of the dew-heater, and some other pics related to it's installation and working. As I mentioned to you earlier, the internal looks very chaotic, but for me they are very clear and well labelled (though only one label is visible in the pics attached), and insulated.

The dew heater's plastic box itself is glued to thick cardboard using hot glue, and then a candy stick is hot-glued horizontally to the top of the cardboard, and wedged between the telescope body and two mounting rings.

The entire dew-heater/power box is itself powered by 16 AWG umbilical cord (13 amps capacity) attached to 12v 30Amps power supply (using XT60 power plug). Dew heater has three 12v (5.5 x 2.1mm dc female jack) and one 5v 3amps USB output (through buck converter). One of the 12v output is further reduced to 6volt (for secondary mirror heater) using buck converter.

DS18B20 Sensor jacks are regular 3 pin stereo jacks, and cables for the sensors and secondary mirror heater are made up of the thin cables salvaged from an old 10 feet HDMI cable. Primary mirror heater cable is 22awg cable, and protected by 2amps mini fuse.

EQ6-R Pro mount has its own power supply.
Pictures attached.
