It comes with a dust cover, so no worries ;)
Oh well, haha! I watched microbehunters review, looks like a real cool microscope. Are you using any other lighting than the integrated led?
And the camera adapter, this is not just a plastic (or metal) part to fit into the tube so the camera would use the actual microscope lens, but it's something that has its own optics too?
Maybe with some kind of water gun ๐
My neighbor's cats were also stalking around the feeder in our garden, but luckily they seem to only be out occasionally.
