Hi All well after a 3 month away from my telescope because of weather and other things I finally got back to it over the last few days. I was having trouble getting my stars pinpoint ,the best I could get was stars with tails ,thing it was a collimation problem. Before starting I shone a torch down the tube and there it was a mud wasp nest on the inside the tube.
What would be the best way of cleaning it out
