The cap on my polar scope ain't come off since I've been here (besides one accident!) and given how faint the asterism is, there's next to no chance of seeing at anywhere except a good dark site.
Given the FOV of the polar scope, it'll get you in the ball park no doubt, but once you get the focal length of a scope onboard you'll highlight how far off it could be. The last couple of times out, I've taken my C8 along for polar alignment, before switch scopes for imaging
