Welcome to CoCoRaHS!
I know that the snow season is coming to an end, but I would strongly suggest getting an extra outer cylinder for snow measurements. I actually have two extra cylinders, one a spare and the other from my old "Weather Channel" gauge (the same gauge). When I catch snow in the outer cylinder, I immediately swap it out with the empty spare, then melt the catch.
The old cylinder is used for core snow measurement.
I too was thrown off by the photo, but I realized that your metal pole is a bit away from that gazebo. It is not as bad as first thought, where it appeared that the roof runoff would go into the gauge as well as being blocked. I would agree that you need to move it a bit farther out. I could not meet the "guidelines" myself, and placed my gauge equidistant between the house and detached garage. I reviewed it with my NWS CoCoRaHS coordinator and he thought it was OK. I was particularly concerned about the overhead power/cable wires even though they were not directly overhead. Sometimes you just have to do the best you can.
I actually have my CoCoRaHS gauge in a similar setup. I had an old pipe with a floor flange. I attached the flange to a deck block, and attached a 1x4 board with conduit clamps. The deck block is stable and did not tip in 34mph winds. (highest we have had since installing it).
