Here you see the modification to the Telrad mount that I made. Originally, the mounting plate was attached to the metal tube you see behind the Telrad. It was held on using a couple of zip ties.

I moved the Telrad mount over closer to the focuser, so that it's much easier to look through when you're on top of the ladder. The old location made for too much of an uncomfortable stretch to look through the Telrad.
As you can see, I also added a couple of wood blocks to raise the Telrad up to its previous distance from the surface of the UTA. These blocks give it about the same distance as the tube did.

I decided to add a dew shield for the Telrad. It's very annoying when you try to use the Telrad to align an object, only to find that the surface of the Telrad is misted over.
I used a 2 liter soda bottle, since the diameter is about what I need to clear the outermost edge of the Telrad, and because it's very easy to cut.

I cut the top and bottom off of the bottle, leaving me with a cylinder.

I then cut the cylinder in half, lengthwise. This gives me two half-cylinders.

The two halves are held together with double-stick tape. I used self-adhesive velcro to attach the shield to the Telrad. It's a little hard to see in this image (photographing transparent objects is tricky) but you can see how the shield will protect against dew forming on the angled surface of the Telrad's reflector plate, and from forming on the reticle lens.
This is still a work-in-progress. I'll see how well this works, and make any further adjustments to it afterwards.
