: I posed this question last fall & got all-negative responses. Here in central Canada, the problem is VERY cold winter temperatures.

Are you trying to protect the telescope or yourself from the VERY cold temperatures? My own experience in Northern Michigan and upstate New York indicate that the telescope works very well at low temperatures if the seeing is good. If image quality is the highest priority, it would be worthwhile to buy subzero boots and electric socks etc. rather than possibly compromising image quality for creature comfort. Traditionally, astronomers have been a hardy bunch.
