Works great, used with an orion dew zapper

These 12v dew heaters are great and come in many sizes. Sadly, they use an RCA plug (one of 2 standards in the telescope industry). I need a 12v 5.5 mm x 2.1 mm barrel connector. The two wires inside the power cable are small, but I managed to cut the end off and solder on a barrel connector. Because this is a heater element, the orientation of the wires does not matter. As a bonus, I was able to cut the wire to a shorter custom length so that makes my telescope rig look less like spaghetti wiring and also, less excess wire to have things snag as the mount moves.

I use this lens warmer on those cold late night Milky Way picture taking sessions. Never had a lens fog up while using this warmer. At 12 volts this warmer pulls about 350mA so run time with my custom battery (16 AA Ni-MH 2.4KmA/Hour and a 12 volt regulator) box is about 6 hours. Current draw was less than expected. Warming capacity more than expected.

The band works great, but the RCA plug is cheap and after only a few uses the outer metal on the plug started to bend. It got to the point where when I plugged mine in, the outer "Negative" of the plug was so loose and flexible that it was touching the "positive" metal rod thing and I did not notice it because it was dark plugged it in and I Blew 2 fuses on my Dew Controller. Luckily I had extra fuses.Other then that the heating band works great so far. I would of gave it 5 stars if they didn't skimp out on the quality of the Male RCA plug. I now had to cut the plug off and wire a new plug in. One that does not have those metal tabs that connect female jack.

A great and useful telescope accessory. They do an absolutely perfect job of keeping the optics a few degrees above the dew point. Therefore, even on the most humid of summer nights, they keep everything dew free and dry. Highly recommend these.
