You'll need a good tracking mount to use a 400mm lens. It will be easy with a proper german equatorial mount but it won't be easy with the usual lightweight nightscape trackers.

You could take say 100 x 10 second images and stack them in Deep Sky Stacker.

Even 10 seconds will show elongated stars without tracking.

Consider that in your decision making. You are imaging a moving object and they move faster than they appear just looking at the night sky.

You'd be better off costwise and performance wise with a small APO telescope which are around $1000 these days.
