I have a C8 on a tripod that I don't use as much as I'd like. One thing is my proximity to Chicago (45 miles NW of the city - not quite far enough away). Also, as my yard is set up, it's a real pain to take it in and out of the house. I'm not ready to build a shed observatory around it, so I was wondering if it would be bad for the scope to leave it out all the time. Even just leaving the tripod out would be better, but the best would be to keep the whole setup out all the time. I saw a protective cover for about $150 that claims to do just what I want ( http://www.optcorp.com/productList.aspx?uid=&pg=0&kw=cover&st=2 ). Does anyone here have any experience with such a thing? I'd hate to put my scope at risk of damage from condensation or anything else. Will this really do what I want? Are there any other alternatives people have used?
