I have two reasons why I don't leave it set up Pat. SWMBO won't have a bar of it sitting on the end of our patio, which is the only place that I can escape from street lights.
I put my BBQ cover over it one night, and in the morning every inch of the scope, mount, and tripod was absolutely streaming with condensation; a good job I took the H/C and cable indoors. I had to remove all the bolts and dry them before they rusted.
Gradients are from four streetlights, and from the lights of town in the west. I have a filter, but it doesn't do much at all with modern
streetlights.
