Just ordered one. Maybe two?
Very high humidity here in S.C.
I also use a TGZ 365

The Goldenrod gets warm, not hot.  I can easily touch it when it’s running.


To mount it, I used the plastic stand-offs included with the Goldenrods and attached them to thin strips of plywood.  I then zip tie the plywood strips to the turnbuckles on my portable field pier.

Since the goldenrod gets hot, how do you attach it to the mount?

Ouch! Happened to me TWICE! Once with one of those "red" mounts and then once when a few of the critters got into the OTA of my Planewave 12.5" and down behind the primary and ate EVERYTHING. OMG. What a mess. In both cases the cost of repair was high. And my insurance policy explicitly lists mice under "Not covered for damage by vermin".

Lat week during an imaging session in my observatory I happened to see a mouse rappelling down the power cord on my nearby 1600 mount. Rather strange, I thought, that mice would use wires as highways up and down a telescope pier.


Then last night, as I was getting ready to do some imaging with the 17" astrograph on that 1600 mount, I ran into a familiar problem. The Dec axis ran for 1 second and stopped, with the yellow light coming on in the CP4 controller. I looked up the open hole in the back of the RA (yes I forgot to put the plug back in last August) and saw some shredded paper way up in the Dec axis cavity. I knew then I had to get into the Dec axis and check out the damage.


Since I had a large astrograph on the mount, I decided to put the mount counterweight down, scope on top and lock the axes clutch knobs tight. Without removing the scope, I removed all the counterweights, the counterweight shaft and unscrewed the counterweight adapter from the end of the Dec axis. Here's what it looked like:



After cleaning out the mess:



The mice had chewed on all the wires and broke several of them. Fortunately I have lots of practice soldering. I pulled out the Dec connector wire along with the crossover box:



The mice had damage 6 of the 8 wires. With some matching pieces of wire, some heat shrink tubing I spliced in the damaged portions:



Finished cable wrapped with some electrical tape. Did it work? YES, the mount is back in business and the scope is imaging again.
