I've got a spider living in my astrograph!!
Well, you know the way you always look down the tube of your astrograph when you remove the cover.. Not sure what I expect to see except a very unattractive view of my face! One day I did this as usual but saw a lot of lines. Scratches on my mirror I thought. Oh no! But on better examination with a light (don't do this as you will see every imperfection and think your mirror needs cleaning which it most likely does not) I could see that it was a spiders web. What to do?
I got a short cane and being careful not to hit anything like baffles or mirror I got them out. Job well done. Not that it probably would have made any difference to my observing, but I just felt that my poor scope inside had somehow been desicrated.
I did have a few nightmares about looking down the scope one day and not being able to see the mirror for spiders and webs.
I had largely got over this obsession and even got used to taking the cover off the scope without shining a torch down it. When it happened again! This time it was war!!! No spider would live in my scope and get away with it. A nice sheltered cosy environment with central heating and even a dehumidifier! So next day I unlocked the dome removed the scope cover and looked in. Sure enough there it was a tiny spider in the middle of a new web. I immediately got a bit of dowel and tried to get it and it's web out.
No such luck it took of like a scared rabbit down into the baffles. I was now on a mission.
I thought for a couple of days and decided that high technology was the only way. So I made a special adapter for a very poweful workshop vacuum cleaner to allow me to clean in between the baffles. It was made of 5 lens brushes and two short lengths of plastic tube. I also got a large dentist mirror from a mechanic friend and a flex light used for looking in gearboxes.
I was ready!
Next day came. cover of the scope. There he, or more likely she, was. Sitting on the edge of the very first baffle. slowly slowly I got everything running and pounced. Got ya!! End of one spider.
I now still check, but no more so far. I also dont leave the scope cover off when I am not using it. Only damage was what lloks like a mirror scratch but is really a strand of cobweb, just to remide me of the power or insects!
