It looks like a very good solution, but I'm a bit concerned about that big white flap reflecting stray light back into the telescope when it's not being used. As is I have to set up an elaborate scheme off garden umbrellas to block stray light from street lights and neighbours back yard light. Also a bit concerned about having a large wind sail at the end of scope
If your using one what are your thoughts on it?
Cheers
