Ok all the cheap people… here it is 🤪 Total cost is $1.30
Got a piece of Eva foam. I picked the 5mm thick. You can get thicker if you want more structure but even 5mm holds the shape just fine. You can make the shield as long as you want given it weighs almost nothing there will be no weight problem overloading the motor. The black foam is black, no shine, perfect. It is also quite porous so dew will be absorbed if it happens.
Normally you would use a heat gun to shape the Eva but I do not have one so I just held it on top of my electric stove and shaped with my fingers. Images show the process but let me describe a bit:
1) cut a strip of foam. I cut a bit less than 13 inches. You can do longer if you want the shield to fall off when the arm is closing
2) scotch tape to get a tube
3) now you just need to get one side of the tube to be flat. Heat the foam and press it against a flat surface. Repeat till you get it right
4) I heated and stretched one end of the tube so it is easier to put it on the scope
5) super glue the seem
6) do a cheap guy victory dance 🕺
Given it is super cloudy in my area I have not tried this masterpiece yet….
